Chapter Two: Literature Review

Introduction

Cloud computing has intensely grown to be one of the most deployed services because of its relative benefits and advantages to firms, organizations, and enterprises. There are four main service deployment models of cloud computing, whereby the models differ according to physical and foundational infrastructure layers (Amron et al., 2017). The models include hybrid cloud, community cloud, private and public cloud. The central service model is a platform as a service, software as a service, and infrastructure as a service.

The complexity of healthcare information systems has been the leading cause of the shift from traditional to modern mobile-based technology systems, as cloud computing helps incorporate solutions to the technologies while adopting new information technology outsourcing (Amron et al., 2017). Apart from improving service quality and meeting various healthcare needs, cloud computing also aids in storing and sharing information such as electric health records and opening new horizons for patients (Amron et al., 2017).

On a theoretical framework, all cloud computing models applicable shall be examined in review on technological aspect, organization-environmental framework aspect, and technological innovation. All the currently and internally adopted technologies used in an organization and accessibility shall be reviewed (Gao &Sunyaev, 2019). The organizational context will also include organizational constructions like scope, managerial structure, and size. In contrast, the environmental context will comprise all the factors related to the healthcare facility's environment and operates as an industry and the competitors.

The various contexts will respectively present the opportunities and the constraints for technological innovation. The technological-organizational-environmental framework being the organizational-level theory, will provide a different perspective of framework that will include internal and external factors (Amron et al., 2017). The framework will classify and determine the factors. It will also provide free space for categorizing the various attributes in different contexts in a broader realm as the cofactors in every context are obtained from previous studies.

Once the literature has been reviewed, the TOE framework is combined with the various theories to identify specific factors. The framework will also be integrated with the other models that offer a more comprehensive range of constructs to have a sizeable theoretical ground for understanding different adoption attributes (Gao &Sunyaev, 2019). The two-theory study that needs to be integrated here is the diffusion of innovation and technological-organization-environmental theory. The two models complement one another in terms of knowledge of innovation attributes, explaining different inter-organizational levels instead of just individual stories (Amron et al., 2017).

The advantage of this framework is that it only allows and encourages researchers to identify many factors concerning different contexts (Ali et al., 2018). However, the most frequent factors chosen by the most empirical types of research due to its importance in the adoption of cloud computing remain the most reviewed one then it shall be followed by its adoption on the organization's top management support, barriers perceived under the healthcare facilities, and organizational readiness. In addition to competitive pressure, rules and regulations are under the environmental aspect (Amron et al., 2017).

Literature review

Cloud technology in health facilities is a kind of cloud computing that is used to improve patient treatment. It can solve some of the shortcomings of healthcare systems by using cloud computing (Ali et al., 2018). The capacity to access medical information from any location and at any time can significantly enhance quality healthcare. Cloud computing may be utilized to get accessibility to health information and, as a result, improve the efficiency of medicine delivery. Because cloud computing is often used in a sharing and accessible setting, it is vulnerable to criminal data theft, assaults, and data redundancy (Amron et al., 2017).

Widespread security threats hinder the adoption of cloud technology solutions in the medical sector. Healthcare professionals are wary about cloud computing because cybercriminals may obtain sensitive medical information (Ali et al., 2018). As a result, legitimate security issues exist. Cloud services service vendors should address security issues to foster more confidence between healthcare professionals and clients. According to a study, an increasing amount of healthcare institutions want to adopt cloud technology solutions to take advantage of cloud technology (Ali et al., 2018). The deployment of digitalization has, as initially stated, provided numerous implementations for the healthcare sector, particularly in terms of planning and safety. Regardless of the critical issues associated with delivering clinical attention, the hospital sector is very complicated. Healthcare involves a diverse range of participants with diverse objectives and business characteristics (Ayoobkhan & Asirvatham, 2017). As a result, cloud computing in medicine is complex, and its implementation via healthcare organizations can only be guaranteed under most conditions.

Many significant issues connected with these circumstances should be considered while establishing cloud computing systems (Amron et al., 2017). A cloud computing deployment choice made without careful consideration of the deciding variables may not only impede the effective use of cloud technology in the medical system. Still, it can also create issues for the organization.

Electronic health record cloud computing solutions are changing medicine by offering users new procedures that were not previously feasible a generation ago. According to experts, advanced online healthcare cloud computing technologies will eventually become the creative foundation of modern healthcare delivery (Ayoobkhan & Asirvatham, 2017). Highlighted the advantages of adopting e-health cloud technology platforms to improve diagnostics in various scenarios, including Cloud computing gadgets offer doctors with clinical information guidelines that help them enhance their patient's recovery time effectiveness (Amron et al., 2017).

Cloud computing opportunities in healthcare

Regarding several types of research, medical errors in the healthcare industry are primarily because of inadequate limited access and communication to patient records. CC was perceived as a possible way of improving healthcare performance and reducing medical errors, just as increasing service delivery, investment returns, and even medical research. Moreover, data can be transferred throughout several models with CC, which is recently absent in several healthcare facilities. CC could enable doctors' references, electronic health records, prescriptions, and diagnoses to get shared throughout multiple models. This is currently taking place in the radiological sector, with several facilities utilizing cloud computing to share images and save money on storage (Gao et al., 2018). CC has allowed hospitals, medical practitioners, and even pharmaceutical businesses to collaborate to share patient data, leading to more efficiency and excellent quality services.

Moreover, due to carbon emissions, the old ICT models have not been environmentally friendly. Due to cloud computing enables lower energy use based on usage, the data storage facilities are inexpensive to operate. It also needs few materials for cooling, thus being releasing fewer harmful emissions into the surrounding. This is one of major motivators for CC use in healthcare as the surrounding impact is minimized. Lastly, due to human life being valuable and the resource in medicine being limited, eHealth services match a cost-effective context where the patients along with the company benefit from the new technology through enhancing the patient service quality via a shared, powerfully integrated platform along with coordinating care, the medical process just as minimizing IT infrastructure cost of investing thus leading to a better healthcare surrounding, (Atianashie Miracle &Adaobi,, 2014.)

Benefits of CC in Healthcare

Multiple benefits accompany CC adoption in the sector of healthcare. The first benefit is that CC brings economic relevance to organizations of healthcare. It is unexpected for CC to offer economic benefits. In general, the utilization of CC is due to short-term interests in the economy. Several pieces of research such that CC has the principal merit of low cost I healthcare. CC plays the role of reducing overall IT maintenance tasks and thus aids them in preventing likely IT reinvestments. The second advantage is that CC mainly targets the clinical tasks through leveraging great scalability. Some research shows that the old health IT focused on administrative, financial, and even strategic functions instead of clinical activities. Such findings promote the urgent need to utilize CC to remedy the old health deficiencies in the context of the healthcare company's clinical activities. CC adoption has the advantage of great scalability with a focus on the clinical sectors. The third benefit is that CC supports patient-centeredness. A conservative yet well-acknowledged perception of health IT is medical staffs are critical users of IT applications, and several existing IT applications focus heavily on physicians. Yet, it has been claimed that the great potential of CC is that it realizes patient-centeredness, which is a promising upcoming trend of health IT. Moreover, several surveys suggest that CC innovatively includes patient family members for realizing patient-centeredness. It has also been noted that CC promotes service flexibility and mobility (Gao et al., 2018).

Factors influencing CC adoption in healthcare

Identification of factors affecting adoption in cloud computing innovations in deploying HIS has obtained insufficient attention in academic literature; thus, there is a lack of rigor and systematic analysis studies. The following are factors affecting the perception towards using eHealth:

System integrity domain factors

In the system integrity domain, system features have been known to affect the way persons manage tasks. This is usually featured through the personal perception of a model to finish specific task demands. Regarding Hsiu-Fen, establishing the successful utilization of innovations needs examining model features as outside variables for adopting with regards to driving a belief of its usefulness and effectiveness. The first system characteristic can be compatibility which refers to how the modern model fits the personal existing values and current needs. The research postulates that determining the fit of HIS and personal needs is essential for structuring the utilization behavior of the model (Meri et al., 2017). Compatibility is another essential aspect to be considered when examining the current innovation adoption. With regards to Jen-Her, compatibility of HIS vitally affects approval by professionals of healthcare.

The next factor, compatibility, refers to the degree to which innovation is viewed as hard to understand and employ. It has been known that using CC in the healthcare domain can lead to some issues for people lacking technological expertise, just as IT specialists. This is due to the ease of integrating cloud HIS into healthcare sectors, leading to higher utilization chances. Nevertheless, the complexity of new roles and services in cloud HIS can be challenging for professionals lacking expertise in technology. The model's complexity is linked with how persons view innovations to be relevant to their experiences. Moreover, it gets correlated with the mental efforts of users needed to utilize the system.

In addition, there is data security and privacy as another component of the system integrity domain. The continuous increase in using trending innovations in healthcare practices led to the modulation of conventional approaches to handling patient data. In current healthcare practices, healthcare experts with various privileges require accessing patient data through any device at any moment in the cloud. Thus, various documents have shown the relevance of security focusing on users using CC. Security vulnerabilities get defined as a threat with concerns of destruction, data modification, and denial of service just as disclosure, fraud, waste, and abuse. Users have been warned not to trust the current security measures. With CC security focus is more feasible, thus having the security of cloud HIS positively affects physicians' approval of CC (Meri et al, 2019). Besides the system integrity domain, there are other factors needed for considerations, they include;

Hardware and software modularity

In the context of hardware modularity, there are multiple limitations of present hardware in the healthcare organizations that recourses generalization of using the HIS. Ensuring that there is enough hardware modularity can enhance healthcare application's scalability by embedding critical devices for developing and debugging various health-associated issues from a department to several ones (Meri et al., 2017). Thus, giving healthcare employers enough hardware equipment that vitally elevates their confirmation of the effectiveness to handle along with communicating healthcare data over departments. In software modularity, the process linked with performing multiple tasks within a system can somehow be associated with modularity for tailoring process development just as comprehensibility.

Several research asserted that the effectiveness of regarding the factor when it

turns to CC adoption where there is assurance that the previous platforms can manage cloud application could elevate the acceptance of healthcare employees to use cloud services. Moreover, the organizations need to ensure that their software is up to date to aid in maintaining the correct innovation with regards to flexibility of the IT infrastructure that conforms to means that applications get reconfigured with fewer efforts. Ensuring modularity of software and hardware can impact the worker's view in a positive way; thus, employing CC in healthcare is much efficient (Meri et al., 2017).

Internet network

It has been noted that the lack of connectivity in internet networks like one of the determinants limiting using the adoption of innovation. Network refers to the infrastructure of telecommunication needed for connecting multiple healthcare areas and the users in a state. However, the workers still face more difficulties in sharing and communicating the health-linked data throughout departments because of the limited accessibility to enough basic infrastructure. Several researchers suggest a need for excellent network quality to influence the adoption of CC positively. According to Steinbart and Nath, computer network refers to a critical element driving company management (Osplabs, 2018). Thus, network factors can positively influence users' usage experience because they shape IT use decisions.

Training availability

Training refers to access resources that companies give workers to achieve the expertise required for operating and using innovation. The workers are aided by training availability through boosting their confidence in utilizing the cloud technology in the model, like understanding each capability of the provided innovation can make them approve it more. With regards to Eley and his colleagues claimed the relevance of delivering such resources for taking advantage in telemedicine innovations within care and management of the patient. It is also known that the lack of training resources can lead the users to have opposing views on the innovation expectations, (Meri et al., 2017)

The impacts to the adoption of cloud computing in health care

Like any other new technology, cloud computing needs to be thoroughly tested since it is widely used (Ali et al., 2018). In the perspective of both potential and difficulties, just several doctoral dissertations have comprehensively investigated the influence of cloud technology on care services information technology. Considering the views of administration, infrastructure, and safety, this research seeks to find the challenges that affect the incorporation of cloud computing into the health sector and the recommendations on the steps to be carried out to help overcome these challenges, the influence that clouds computing has to the health sector and the methods of facilitating the acceptance of cloud computing into the health sector so that considerable improvements can be seen (Amron et al., 2017).

Administration challenges of cloud computing

The key issues are the absence of consumer confidence in safety and confidentiality issues in the data sector of the organizational lethargy, lack of accountability, and adherence by doubtful vendors (Dauwed et al., 2018). Challenges occur when their crucial information and expedition programs shift to cloud services, whereby vendors might not assure their data protection with safeguards' efficiency (Govinda, &Ramasubbareddy, 2018). Societal opposition to information exchange and conventional operational environments is a typical cloud service administrative difficulty. A sales contract may not be binding to enable the customer to audit their data in certain situations (Gao &Sunyaev, 2019). Records management breach might have a severe effect on the tactics of a data center and hence on the ability to fulfill its purpose and objectives.

Technology challenges of cloud computing

Numerous cloud-related technological issues involve assets fatigue, operational volatility, information shut, memory management, constraints, and defects in vast and complex cloud environments. Due to heavy rivalry, significant suppliers crowd the marketplace, and many cloud vendors overextend computing power to lure consumers (Shepherd, 2019). To sustain income, the moral framework cut shortcuts so that they may, for instance, block connectivity to cloud assets, employ outdated virtualization, or install older Processor architecture.

This disparity among consumer expectations and what the supplier can realistically supply is a significant technological issue for the cloud client to give maximum support to their users (Osplabs. 2018). Mobile check is also a significant problem in certain circumstances; cloud customers may need to relocate information or capabilities to another supplier or return to the technology system. If the supplier stops commerce or function, software clients may notice a transmission power congestion due to limited actual network infrastructure. Another particular technological concern is flawed in massive data centers (Sharma et al., 2020). Relative to IT platforms, the mistakes in these enormous dispersed architectures are harder to troubleshoot.

Security challenges

IT usage has various data security threats, such as hacker assaults, network outages, natural catastrophes, partition breakdown, urban planning, functionality, improper cryptography access control, and misuse of privileges (Shepherd, 2019). Isolation breakdown, governance functionality, bad cryptographic critical administration, and authority misuse are particular threats to cloud technology. If somehow the supplier does not isolate the services, it might pose significant safety problems.

In the illustration, a client wishes to remove data stored in a computing server; as with other web browsers, this would not instantly lead to genuine data erasure. The information is still stored on the drive but still missing (Sharma et al., 2020). Other clients utilize physical hardware in numerous tenancies. In this situation, a foreign entity might obtain removed data from another client. These pose a more significant risk to internet clients than underlying servers. Improper access control may lead to loss of cryptographic algorithms, exposure of private keys or credentials to hostile persons, or illegal verification usage.

Despite the benefits of cloud computing in e-health services, information security is questionable. Security problems have turned more complex in cloud models and need additional investments to deploy data management policies. For each predictable event in health care cloud computing, primary data need to be registered and accepted by the important people to propose and take the required measures. The data kept in cloud virtualized surroundings can be accessed via several people; thus, healthcare cloud computing has multiple issues and concerns involving data transmission and access control. Meanwhile, when users keep and transfer the information on the cloud, the integrity of the data set and issues associated with moving data is quite a difficult task. However, when health information is stored in the cloud, patients lose physical control of their private information (Mehraeen et al., 2017).

Achieving security along with privacy within e-health is very crucial in obtaining the aims of utilizing modern technology. This is necessary as digitizing health-associated data along with sharing them can lead to various kinds of attacks. Various government health institutions have developed a framework for ensuring an excellent level of safety and privacy. For example, the HIPAA was put across by US Congress in 1996 as federal law applies for the US healthcare industry. Following HIPAA guidelines, a combination of valuable security and privacy requirements must be put to effectively utilize e-Health, (Azeez & Van der Vyver., 2019).

As noticed, the safe exchange of e-health information within the company needs standards for security measures and privacy protection. There have been vital privacy and security issues with e-health systems. One of which is access control and authentication. This is needed to make sure there is proper confidentiality and authorization for patient records. Reliable, robust, and standards forms of authentication are specifically relevant requirements for safeguarding patient privacy. The second issue is data integrity. Ensuring integrity is one of the crucial keys in e-health systems like HER since it guarantees the precise of data, thus reducing error and enhancing patient safety. Incorrect input of staff data between paper and electronic medical records leads to such errors (Bajrić, 2020).

The next issue is system availability which is needed for attaining the continuity of EHR to ensure the best services. It claims that the system does not need to be considered to a particular time of day; otherwise, the physician's job will get difficult since decisions can never be made in real-time as needed. Another issue is data loss which is essential to safeguard against. In the case of data loss, there is a need to achieve data recovery, which can get challenging due to hardware and software errors, security attacks, or network errors. The last security issue is network security. Data protection is crucial when the security of critical assets depends on network security. Disruption to network functionality and denial service attacks can impact healthcare delivery, Bajrić, (2020).

Unintended consequences

Apart from safety concerns, Meeks and his colleagues show that the IT solutions like her can contribute to other unintended consequences due to issues of usability, disruptions of clinical processes, and unsafe workarounds. The unintended consequences of HER solutions cast doubts on the system's reliability for improving the quality of care and reducing medical errors. Commonly, unintended consequences are hard to classify into a category since they are side effects of hidden social-technical system factors, Vanderhook & Abraham., (2017).

Possible solutions to challenges facing cloud computing

The solutions to administration challenges can be solved by enabling a transparent platform that assures the consumers that their data is well handled. In cases of any threats occurring in the cloud services of the healthcare patients, the administration should be able to respond while alerting the clients on taking specific measures that might mitigate the risk, such as changing the log-in credentials (Osplabs, 2018). The healthcare administration also needs to guarantee that their consumer's data are backed up in case of any emergency the private details are secure from being tampered with. Another measure that the administration needs to put in place to entice more consumers and hold on to their previous clients is providing a recovering method and setting up a customer care service where queries concerning their data can be audited (Meri et al., 2018). On the side of the healthcare service vendors' technology solutions on cloud computing technology, creating an online platform should be a basic necessity (Osplabs, 2018). Computing mobile healthcare applications with broad interaction capabilities, patient registration, patients' hospital information, communication, healthcare, and more need to be catered. That's where the professionals can construct customized bridge eHealth cloud apps with desktop and Mobile compliance and sophisticated capability to build new features and integrate with external networks.

On the security challenges, specific measures and conditions need to be applied in the cloud technology software to eliminate hackers who aim to tamper with the patients' data (Osplabs, 2018). This involves creating many coded layers with information technology experts capable of mitigating any risk and alarming it whenever there are signs of an invasion. Implementing a rigorous software solution safety procedure and evolving hospital culture ensures data protection is reasonable progress (Sabbah et al., 2019). There is also a need to educating and equipping Information systems professionals to manage safety concerns with a suitable response.

Cryptographic solutions

The ongoing advancements of IT along with data communication strengthen the exchange of greatly sensitive medical data. Electronic health systems get widely utilized, and several facilities depend on transmission and the receipts of medical information. Over past years, several security models were introduced to monitor the privacy of patients and ensure the safety of medical data exchanged. Cryptography was a technique that frequently gives security for HIS. Cryptographic approaches allow one to several computations to occur directly from data encrypted, regardless of defining them. As such, the schemes f encryption with homo-morphic structures gets helpful in creating confidentiality agreements, where the confidential information stays safeguarded during the exchange, processing, and even storage.

Cryptography refers to compiling, validating information, and sharing it through conferences to monitor the data set up for investigation. They have been countless approaches suggested for protecting patient health care information. Nevertheless, cryptography methods can either be symmetric-key or asymmetric-key, where the previous utilization of similar encryption along with coding key while the other utilizes various keys (Sivan &Zukarnain, 2021). Moreover, there is the use of Access Control Manager, where the managers of access control utilize tokens for accessing their classified records kept in the cloud where servers perform users’ identification and determine the access rights through AAM servers.

Authorization as solution

Authorization typically gives the extent to which approved users can enter the system after a correct authentication. It usually comes for a system after correct authentication and giving user privileges to access the system. In computer models, RBAC refers to a model that gives limited entry based on privileges for the user after correct authentication. The models of RBAC involve RBAC0, which is the basic model with basic needs of security with regards to access control (Keshta & Odeh, 2021). The roles, Permissions, and users get defined regarding the model based on tasks based on Function to Permission and then User to Permission. It is based on rules where a user can serve as a member of various roles, and every role can contain several users.

The second model is RBAC1 which was introduced for increasing the efficiency of models at the administration level. The role hierarchy is of much help when assigning roles to the juniors and seniors in a company. It aids the senior role to have entry to each type of data related to the junior role. However, the junior cannot access senior data. The following model is RBAC which is used in models that cardinality is relevant and utilizes rules of RBAC0 and extra factors for promoting the model's security. It is where the permissions get added for functions of establishing separation among roles. Lastly, there is RBAC3 which is often recalled as the Unified model because it works on each rule of RBAC0 and the other models. RBAC3 aids more constraints and Role Hierarchies. The model is favorable for systems where classified interaction needs to occur (Rashid et al., 2020)

Data Security and Privacy Needs

To enhance the trust in the innovation, CC application in healthcare has several securities needs to be accomplished. The following are the needs of security and privacy for healthcare application of CC;

Authenticity

This requirement refers to the truthfulness of attributions, origins, intentions, and commitment. It is responsible for ensuring that the entity demanding access is authentic. In the healthcare model, the information given by healthcare givers and the identities of entities using such information needs to be verified through the Act of Authentication. The authentication of information is likely to pose unique issues, like man-in-the-middle attacks, and is frequently minimized by combining usernames and passwords. Multiple cryptographic protocols involve most forms of endpoint authentication, particularly for preventing such attacks. Within models of healthcare, both information given by providers along with the identities of consumers need to get verified at each access, Abouelmehdi et al., (2017).

Confidentiality

Confidentiality refers to the act of making sure the patient health information is stored wholly unhanded over to unapproved entities. Delegating the data controls to the cloud increases the risk of data compromises like the data turned accessible to augmented counts of parties. There is an elevation in data compromise threats because of the elevated counted parties, devices, and even e applications included. To make doctor links work effectively, patients must trust the model to safeguard data confidentiality. If the patient feels that information is compromised, he/she can choose the information to disclose to the doctor in the future. The data threat can harm the relationship between doctor and patient and even hamper the correct medical diagnosis or treatment (Keshta &Odeh, 2021).

Availability

For CC in healthcare to serve its role, information needs to present each time. An essential and often overseen aspect in HIS is the availability of information in crucial situations involving carrying out operations even when the authorities misbehave along with the capability of ongoing running even in chances of the security breach. Because of power outages, system upgrades, hardware failure, and denial-of-service attacks, great availability models have to avoid service disruptions. It has the main motive of countering services that can compromise availability (Desai et al, 2011.). It needs to be capable of preserving the usability of the records after the enforcement of the HIPAA privacy and security rules.

Integrity

The following requirement ensures that health data gets captured through the model to an entity are precise along with consistent with intended information and are never modified in any way during storage (Vithanwattana et al., 2017). Utilizing the cloud for an actual application such as eHealth needs perfect reliability for given services. Each eHealth cloud data and services need to have zero errors. Unfair treatment based on erroneous data can carry essential consequences on the health of patients. The Security Rule of HIPAA claims that covered entities need to implement procedures and policies for safeguarding electronic individual healthcare information from incorrect alteration. In healthcare, services storing and manipulating the patient data need to implement verification functionality and integrity functionality, such as nonmedical applications, through means of checksum, before utilizing the data. When integrity fails to check, the application in healthcare must report errors and needs terminate regardless of processing the data.

Access Control

Access control refers to a mechanism for managing access to patient's health information that grants entry to illegitimate entities. The policy of access control relies on privileges and the rights of every authorized practitioner through patients or even a trusted third party. Multiple solutions have been suggested for addressing access control and security concerns (Desai et al., 2011.). The RBAC along with ABAC are the top popular models for applying CC in healthcare.

Audit

This refers to a security measure that makes sure the healthcare model is safe. Audit suggests recording the user's activities in the healthcare models in chronological order, like maintaining a log of each access along with modification of data. Both HITECH and HIPAA need users within healthcare providers' organizations to be put accountable for addressing the patient's safeguarded health information. There are various approaches for maintaining audit controls on the information (Al-Shura et al., 2018).

Data freshness and remanence

Data remanence is the residual representation of data that got erased nominally. This can cause an unintentional attack on data confidentiality. In the healthcare model, data integrity and confidentiality are never enough if the freshness of data is never regarded. Data freshness demands that the health records of patients need to be fresh along with up-to-date. Delays in sending and storing outdated notifications have consequences of data inconsistency, particularly in crucial situations.

Secure transmission

This requirement deals with HIPAA Security Rule, which states that the covered entities need to implement technical security measures for guarding against unauthorized access for the electronic safeguarded health information shared over networks of electronic communications. The 2009 HITECH Act widens the rule to business associates. All the rules of HIPAA cover communication between the covered entities of HIPAA, where the focus is on an adversary who wishes to attain confidential medical information from viewing the network communication among two communicating nodes (Al-Issa et al., 2019)

Nonrepudiation

Repudiation threats are focused on users that deny their signature authenticity after the access of health data. For example, both the doctors and patients can deny signature authenticity after health data is misused in a healthcare scenario. Similar to electronic commerce, CC in healthcare can use digital signatures along with encryptions for establishing nonrepudiation and authenticity (Ianculescu et al., 2020)

Complexity and Compatibility

Other issues arising from the use of cloud computing can be complexity and compatibility. Complexity refers to the level of the perceived difficulty of understanding along with using technology. Meanwhile, compatibility refers to the extent to which an innovation is viewed as consistent with the current values, needs of potential adopters, along with their previous experiences. Complexity and compatibility are vital determinants of adopting cloud computing, (Al-Shura et al., 2018).

Compatibility issue in CC

Introducing and studying new health IT solutions is crucial for considering the sake of enhancing their capability. However, it can attribute to critical interoperability complications among systems. As stated, with the relevant expansion of implementation of new HER solutions, it has been noted that the more development of various and heterogeneous models, the problems of interoperability and compatibility are encountered. While different EMRs, EHRs projects, and software get implemented in health bodies, various analytic services are abundant. Such latter is in the form of machine learning models (Khennou et al., 2018).

Compatibility can get regarded as a critical factor in the decision of deploying an innovation. When companies think of deploying the cloud, compatibility with previous applications is a noticeable concern. This concern rises from the little control that cloud clients have over the rendered computing platforms by the provider; this makes providers assure flexibility. Nevertheless, providers can alter the rendered platforms whenever they want, regardless of the customer's approval. From the developer side, there is a rise in attention toward compatibility centered on attaining an excellent level of integration for innovation (Al-Hujran et al., 2018).

Complexity in CC

Cloud computing along HPC is driven by end-user demand for further greater scale and performance. To attain such needs, heterogeneous resources, typically in the form of novel processor designs, are getting integrated into cloud platforms along with HPC models. The side effect of this is greater complexity, specifically in the case of hyper scale cloud services where the scale of infrastructure, applications, and several end-users is multiple orders of magnitude greater than overall-aim computing and HPC. Such complexity in large-scale models leads to vital management, reliability, security, and security issues (Lynn, 2018).

Emergence and the associated concept of self-organization, self-management, and separation of concerns are design principles that get proposed like potential solutions for handling complexity in huge-scale distributed information models. The complexity of hyperspace cloud models makes it very infeasible for cloud services providers to foresee and manage manually. Each possible configuration, end-user operations, and component interactions on a detailed level due to significant levels of dynamism in the model. Self-organization has roots in natural sciences and studying realistic models. It has long been recognized that greater-level outputs in dynamic models can serve as an emergent effect of minimum-level inputs (Lynn, 2018).

There are various keys to note for having a secure cloud architecture. One of which has a single sign-on. Within the cloud computing ecosystem, workers log in to multiple applications along with services. This makes it hard to use strong authentication at the user level. To counter such an issue, streamline security management along with implementing single-on users for the cloud. This allows users to access multiple applications and services in cloud computing surrounding via a single point, thus enabling strong authentication at the user level (Tripathi & Mishra., 2011).

The second point to note is increasing availability. Access to cloud services needs to be available each time, even in times of maintenance. This makes crucial business data kept in the cloud be always present to cloud users, minimizing network downtime, thus increasing business profit. Therefore, can be performed through implementing significant availability innovations like active clustering, dynamic server load balancing, and ISP load balancing within the network infrastructure. Moreover, there is a need for a defense in depth method. There is a need to have proper layered protection consisting of perimeter safety and intrusion detection and prevention components within the network, (Tripathi & Mishra, 2011).

The use of Cloud Technology and Health Visuals

Mammography is understood as the method of seeing the organism, more especial of humanity, using various techniques to detect, evaluate, or cure various diagnostic problems (Hartmann et al., 2019). Several detection methods are available depending on the equipment utilized and the volume of material included in the picture regarding the body region being inspected. Screening tests comprise X-rays, scanning techniques, magnetic resonance imaging, radiography, sonography, and Computed Tomography.

Throughout generations, microfilm served as the primary medium for previewing and sharing diagnostic pictures among clinicians. Unfortunately, the video was prohibitively expensive, cumbersome, and inefficient due to the possibility of being lost. Shortly on, Digital Drives developed and partly supplanted film as a storage medium. Discs are cheaper costly, more portable, and offer larger memory capacity than other media. Despite this, CDs are susceptible to injury and may remain illegible, result in information failure as a result.

In response to the change in emphasis from providing patient-centered care to promoting patient-centered care, the Photographic Acquisition and Communicating Network were developed to save, handle, acquire and display healthcare pictures (Silva et al., 2014). Image Acquisition and Communicating Network is composed of four components: imaging equipment, storing facilities, terminals for picture viewing, and a connection that connects all of the components of the system. The transmission and dissemination of medical image analysis are accomplished via the Diagnostic Scanning and Connectivity in Healthcare protocol. DICOM allows for exchanging medically diagnostic data across healthcare equipment within the same organization, but not amongst pharmaceutical products in other organizations.

The conversion of medicinal pictures to electronic platforms has had a significant positive impact on healthcare facilities regarding expense reduction, increased efficiency, and the promotion of cooperation amongst health providers (Silva et al., 2014). Cloud technology enables surgeons to use rebuilding equipment hosted in the cloud by signing in to their physical work area using their existing credentials. As clinicians analyze pictures, only instructions and sorting occur at the workplace area, whereas the analytical interpret takes place on cloud storage. Identification procedures are shown on users' gadgets while doctors are working.

Additionally, cloud computing enables users to obtain content from any location and at any time as a timely update is made, eliminating this need for system integration installation and management, reducing overall IT cost. According to some estimates, IT costs are expected to be reduced by twenty percent each year as a result of cloud computing.

How cloud technology is popular in the Field of medical

The hospital sector makes use of a diverse variety of information technology applications, ranging from basic productivity applications such as desktop publishing to more sophisticated biological equipment such as positron emission tomography machines and everything in between (Nomoto et al., 2014). Nonetheless, as opposed to other sectors, the medical industry is approximately ten to fifteen years behind the curve when it comes to adopting information technology.

Hospitals' financial accounts were just the first piece of health information technologies to be used; it was not until the nineties that health information systems were introduced. An EHR system is a phrase that refers to a platform that consolidates all of a participant's clinical records, and the name information management system is also taken to characterize this technology, per the investigator. A journal article healthcare file was the primary method of storing customer records, including diagnostic pictures, doctor remarks, pharmaceutical prescriptions, and other relevant health records. Electronic health records were moved to offer more patient-centered hospital services by reducing medical mistakes, ensuring timely access to correct information, and improving safety procedures. Clients would reap the advantages of new innovation if they had sufficient knowledge and received adequate coaching in its usage. For example, adopting EMRs requires extensive user training as well as significant upfront financial investment before any advantages can be realized.

When compared to other sectors, the acceptance and application of information technology (IT) services in hospitals is sluggish. This, according to the leading analyst, is due to the inability of IT technologies to demonstrate significant reductions in operating expenses while simultaneously improving patient outcomes (Bhatt & Peddoju, 2016). In addition, the interconnected economies across the medical industry were identified as a contributing factor to the delayed implementation of information technology; these interconnected sectors comprise health treatment, hospital coverage, the authorities, and the employment force. It was claimed that delaying IT deployment in the health industry would allow participants to benefit from earlier literature on IT technologies' acceptability and deployment in hospitals, which would help implement these workarounds in the prospective.

In addition, user acceptability is a critical aspect to consider; past expertise with failed solutions may make it more challenging to embrace new information technology innovations. Anxieties that introducing innovative IT alternatives will disrupt the traditional workload of medical practitioners are one of the factors contributing to the sluggish adaptation of innovative IT alternatives (Bhatt &Peddoju, 2016). IT workers role in the care services take responsibility in the sector serve as both authorized personnel and service operators; thus, knowing the requirements and aspirations of their companies may be beneficial in the phase of various digitalization, since employees are a part of the consideration process in this sector. The need for medicinal treatments has risen significantly in recent years, leading to a greater in the weight of medical information as well as an amount of monetary expenses.

Virtualization, as a new information emerging technology, has the opportunity to boost the medical Field by creating an opportunity to regulate and improve service delivery, improving specific, and facilitate information exchange from anywhere at any time, enabling better the performance of public sector to sick people and improving the overall patient experience. It is projected that approximately above thirty percent of healthcare organizations are already using a virtualized technology, with the residual of more than seventy five percent of public health organizations intending to use cloud – based services in the next few years.

Cloud computing offers memory space that is expandable to meet the requirements of the business, resulting in a reduction in healthcare information technology costs. Cloud-based nursing informatics storage provides medical professionals with the advantages of efficient management and updating of their records and improved control over admissions, thus reducing the likelihood of illegal access to patient records (Changming, 2017). Furthermore, cloud-based medical storage capacity allows for participants in the medical sector to maintain conformity to regulatory requirements since digital formats of material can be handled, analyzed, and safeguarded much more easily than paper-based formats.

According to the experts, investigators have brought awareness that the cloud hosting are supplied by third parties, posing dangers to end users since they have no influence from over security and compliance of their content kept on the Internet. To be sure, interacting with a private entity is fairly unusual in the traditional IT context, therefore these dangers are not unique to the cloud system (Changming, 2017). Although this is the case, present and prospective cloud services users are considered to be coldly logical in their concerns since the confidentiality threats are exacerbated in the cloud infrastructure when contrasted to the conventional IT ecosystem.

It is important to note that, in the cloud architecture, existing customers are not only exposed to outside data security threats, which are common among traditional IT systems, but they are also exposed to internal dangers. While other clients who are backed by a certain cloud service get illegal entry to cloud storage, this is referred to as a hazard. The activities of cloud services must address these concerns and provide customers with the assurance that personal information is correctly kept, discreetly guarded, and safeguarded. Infringement of legal rules, as well as the fines and sanctions that arise from them, must be avoided.

The use of big data technology, ubiquitous electronics, and the Internet of Things (IoT) in hospitals

In the course of their daily operations, healthcare professionals produce and gather a significant quantity of knowledge from a diverse range of institutional systems, including computerized medical data, radiological pictures, drugstore purchases, medication records, laboratory results, and workers compensation information (Devi, 2020). With each passing year, the amount of this digital information continues to increase at an enormous speed, attributable mostly to developments in the provider landscape, including as rewards for effective use of electronic health records and a move for valuation monetization strategies. In order to effectively handle a huge number of data, a considerable amount of processing capacity and network connectivity are required. Healthcare organizations are being forced to spend more in IT facilities when it comes to on disk space as the volumes of information being stored grows (Navale&Bourne, 2018). This has resulted in the archiving of significant amounts of healthcare data not being regarded as a feasible alternative for storing such data. Cloud technology, on either way, makes it possible to do any big data activity by providing a huge amount of space and computational power. Virtualized statistical methods also assist clinicians in improving patient management by converting medical information into practical information.

Individual tools in CC of healthcare industry

There are various examples of how the cloud, along with its services have been employed in biomedical task. In genomic, the usage of CC ranges from an application to finished virtual machines with several applications. One of the individual tools used is the

BLAST which is a commonly used tool within bioinformatics research. A server image of BLAST is able to be hosted on Azure, AWS, along GCP public clouds for allowing users to operate stand-alone searches with BLAST. Users also submit searches utilizing BLAT via the NCBI API to operate on Google Compute Engine and AWS. Moreover, the Microsoft Azure platform gets leveraged for executing huge BLAST sequence databases from NCBI, operate different BLAST programs on specified input from the sequence databases, and produce visualizations from results for analysis that is easy (Devi, 2020). Azure also gives ways of creating a web-based user interface for tracking and scheduling the BLAST match tasks, managing users, visualizing results along with performing basic tasks.

Another tool is the Cloud Aligner which is known for its speed and full-characterized MapReduce-based equipment tool for mapping sequences, tailored for being able to handle the long sequences, while Cloudburst gives great sensitive short read mapping with MapReduce. Great-throughput sequencing analysis is able to be conducted by the Eoulsan package integrated into cloud IaaS surrounding (Navale&Bourne, 2018). For entire genome resequencing analysis, Crossbow remains the scalable software pipeline. Crossbow integrates Bowtie, a memory-efficient, and ultrafast short read aligner, along with SoapSNP, which is the genotype, in an automatic parallel pipeline running in the cloud.

Microsoft Azure platform in healthcare

One of the most common cloud platforms is Microsoft Azure which is a provider involving the IaaS, PaaS along with SaaS developed by Microsoft utilizing its network of data centers that keeps on expanding all over the globe, as it gives a variety of CC, storage along with application services for every kind of users from business sector along with institutions. It enables the development of applications and services for each kind of user from the business sector and institutions. It enables the development of services and applications, examination, dissemination, and management over the vast worldwide network using special tools and frameworks. Privacy and security are also involved on the Azure platform. The platform provides the ability to store data safely with ready entry while increasing the storage space at any moment, depending on the business activity of the user. In the case of CC services, the cost is based on space consumed, and the total expense is computed regarding hours of access along with data usage. It also gives the chance of developing applications with ease along with publishing compatible apps worldwide on each web platform and mobile phone spread, along with being able to create and respond rapidly with the capability of managing the web applications along with examining and publishing them with ease, Hassen et al., (2020)

Workflows and platforms

Integration of phenotype, genotype, and clinical data is crucial for biomedical research. Biomedical platforms give an ecosystem for creating an end-to-end infrastructure used for storage and analysis of data acquitted. One of the platforms is the Galaxy which is an open-source used for data-intensive research. For huge-scale data analysis, Galaxy gets hosted in cloud IaaS. It can achieve a highly scalable and reliable cloud-based workflow model for the coming-generation sequencing analyses when integrated with Globus Provision. As a scalable and robust pipeline for NGS analysis is required for the diagnostic task in clinical laboratories, Cloud Man is present on AWS cloud infrastructure. It can be utilized as a platform for sharing tools, data, and analysis consequences. Enhancements in utilizing Cloud Man for analysis in genetic variant has been done through minimizing storage expenses for clinical analysis task, Navale&Bourne, (2018).

Electronic Health data

Electronic health is the use of electronic communication within the sector of healthcare. The technical progress within mobile communication along with networking innovation has resulted in the development of individual systems in e-health. Tele-health is a remote clinical and non-clinical service. Telemedicine is a remote clinical service for patients in remote areas. With the elevating prevalence of tablets and mobiles, it is extensively utilized for supporting the practice of healthcare; developing e-health models, mobile health, telemedicine, e-visits, and e-consultation have turned into an increasing need. Such models are utilized for ongoing monitoring, predictions, diagnosis, and treatment (Mahmoud et al., 2020). As a result, they result in minimized healthcare costs. Patient monitoring models are viewed as important services within mobile health. It aids patients in performing daily activities while the important signs are kept on the radar.

IoT, together with cloud services, add more capabilities that can get divided into three service layers known as IaaS that gives great volume storage like Amazon S3 storage service, PaaS that offers both services and storage like Google App, and SaaS. CC, together with WSN, gives promising monitoring models that facilitate and enhances QoS. It enables actual-time entry to patient data at a time and from any place, allowing preprocessing, analyzing, along sharing data, providing great-volume storage in minimized cost along with reducing the cost in hospitals along with clinics. With regards to S. Pandey, he presented a model that combines mobile computing and CC for analyzing ECG data, where a cloud surrounding was developed for gathering people’s health data like ECG data along with disseminating them to cloud-based information repository that facilitated analysis of data through software services hosted within the cloud. Another person known as Risso provided a Cloud Mobile system used for monitoring respiratory diseases; the system monitor patient Spo2 through wearable sensors then utilizes mobile devices for transmitting to the cloud system, Mahmoud et al., (2020)

ECG Monitoring System

IoT model has enabled designing small devices capable of sensing, processing along with communicating, enabling sensors, embedding devices along with other things developed for assisting the clarifications of the surrounding. This includes the ECG monitoring model, which has been developed along with greatly utilized in the healthcare sector for the past few decades and significantly keeps on evolving over time because of the rise of smart enabling innovations. The architecture of the ECG monitoring system is known to be beneficial in healthcare. In the architecture of ECG, the right silos give processing along with storage services to each process in four horizontal layers. For instance, processed actual-time ECG signals can use edge/fog computing. Also, the cloud infrastructure allows storage along with processing services at several stages of the ECG monitoring lifecycle. Moreover, at the core of its design, security and privacy of data are crucial characteristics that need to be supported in each process where data gets gathered, transferred, analyzed, processed, accessed, and along visualized by several stakeholders. It is also suggested that blockchain technology can be combined to give a trusted, immutable, and decentralized ledger for several transactions which outdo existing approaches, techniques, and mechanisms. It gives a great level of transparency for ensuring privacy and security (Serhani et al., 2020)

The ECG monitoring model is a diagnostic cardiac issue thus plays a critical role. This turns the implementation of the Portable POC model at an inexpensive cost critical with the aim of monitoring the cardiovascular health of patients regardless of competing with daily routine. Moreover, a portable ECG monitoring model with limited shape elements is activated with BLE (Xu, 2020). Indeed, it is true that the healthcare monitoring model in healthcare has experienced vital growth, along with portable healthcare monitoring models with rising technologies that are turning great focus to several countries globally nowadays.

Smart health monitoring approaches, smart home, smart packing, smart city, industrial sites, smart climate, along agricultural fields are the key applications of IoT. The tremendous key use of IoT is providing health and surrounding condition tracking facilities. Heart rate along with body temperature are two key vital indicators for the health of humans (Islam et al., 2020).

IoT applications in healthcare

There are other key main applications of IoT in healthcare. One of which is control of medical equipment and medication control. IoT is used in monitoring the entire process of delivery, production, anti-counterfeit, along with tracing medical equipment and the medications for safeguarding public medical safety. The aspects of the application include robust actual-time monitoring, which makes sure that medicine is delivered and gives a storage environment. The next aspect is the anti-counterfeiting of medicine and therapeutic equipment for recognizing RFID tags placed on a product is hard and unique for recreating. For example, if medicine data is kept in the open database, the patients, along with emergency clients, are able to check the label as per the record set in the open database along with distinguishing the fake meds efficiently and effectively.

IoT is capable of managing medical information, which involves various applications. One of the applications is patient location and tracking, which is a critical asset since it allows prompt reactions in urgent assistance is required. This is specifically for pathologies involving cognitive along with perceptual disorders, epilepsy, Down's syndrome, and even neurodegenerative diseases. The second application is the medical equipment along with medication tracking, the correct records of therapeutic equipment along with drug, uses the necessary data of item use, specific data of item linked with the unfavorable occasion, the origin of the item with quality issues, patients who have used item with quality problems along with districts the item with quality problems hasn’t been used (Syed, 2017). IoT relying on smart bundling approaches for medication boxes can be used for drug management. The approaches have controlled fixing depending on delaminating materials along with constrained through remote communication.

According to Syed the third application, neonatal anti-theft model, which integrates the identification management, neonatal anti-theft along with pathway entry for avoiding the random coming along with going of strangers for giving workable along with robust protection for the coming babies. The following application is in fall prevention along with fall detection due to falls being serious health issues with elders. Detection of falls can be grouped into ambient sensor-based, wearable devices along with vision-based. The next application is that the Medical Emergency Management aids dependable along with productive data stockpiling along with review strategies for RFID technology. Blood data management is another key application as it can maintain the strategic distance from the little limit downside of the bar tags along with acknowledging non-contact recognizable proof for lessening blood pollution, realizing several-target ID along with increment the efficiency of information assortment. Lastly, the alarm system is an application instance where the alert framework aids patients with sending crisis trouble signals in the continuous tracking along with monitoring of patients and clinic therapeutic apparatus, Mohammed, 2020)

Internet of things has the capability of connecting medical devices, sensors and healthcare professionals with an aim of offering quality medical care especially in remote areas. Internet of things play an important role towards improving safety of patient, cost of healthcare is minimized and health care facilities become easily accessible. Efficiency is a key factor in health care and internet of things creates operational efficiency (Martino et al., 2018). IOT enhances technologies, healthcare services and application in coming up with solution to various issues in healthcare. By use of internet of things clinical analyses such as blood sugar test can be conducted at home hence no need of patient to stay at hospital during the treatment period. A device like smartwatch can enhance diagnosing of diseases in health care and doing some necessary monitoring. Internet of things technology has transformed hospital-centric healthcare system to a patient centric system. Through use of telecommunication services clinical data from healthcare can be communicated from remote areas. Telecommunication devices are combined with some advanced technologies which includes machine learning and big data analysis in order to make an improvement towards accessibility of healthcare services and facilities. Internet of things has enhanced; independence and it has distributed the ability of human to interact with outside environment internet of things play a major role of enhancing communication in health industry. In healthcare internet of things is associated with increased accuracy, less cost and it can make predictions about their future in a well-organized manner. Sensors created which are applied to human body through wearing enhances collection of physiological information concerning human body and this information includes things such as temperature, pressure rate, electrocardiograph among many others. Internet of things devices can also help in collecting information in the environment which includes temperature, humidity rate and time. The collection of these information assists in making progressive decisions on patient health and their existing conditions.

Architecture of healthcare internet of things

Framework of internet of things used in healthcare aims at maximizing advantages of internet of things technology and cloud computing with the medicine field. Internet of things offers a framework necessary from transforming patient data from various sensors within the medical devices to a certain healthcare network (Bhatt & Bhatt, 2017). The basic component of internet of things in healthcare are publisher, broker and subscriber.

According to Bhatt & Bhatt Publisher contains network of sensors that are connected and many other medical devices that can work individually or combination with others with an aim of recording important patient information. Information such as blood pressure, oxygen saturation and others once recorded in the publisher they are sent continuously through network and to the broker. The use of broker in internet of things of healthcare is to process and store acquired data into the cloud. Subscriber function is to monitor patient information continuously. the monitored information can be accessed and visualized through technological devices such as smartphone, computer and table (Yuehong et al.,2016) Once the publisher has processed data it gives observation concerning any physiological anomaly or change in the patient health condition. The HIOT makes assimilation in discrete component to hybrid grid. In hybrid grid a specific purpose is dedicated to each component in the internet of things network and the clouds in network of healthcare.

HIOT technologies

In coming up with healthcare internet of things technology used is so crucial since the technology used plays an important role in enhancing ability of IOT system. The technology used are identification technology, communication and location technology. By use of identification technology accessibility of HIOT system becomes possible and the access is from authorized sensor that can be existing in a remote location (AlBar & Hoque 2019). The identification follows a process of assigning a unique identifier to each entity which is authorized hence it can be easily identified hence unambiguous data exchange is achieved. Communication technology used allows connection among different entities in healthcare internet of things network. The technology of communication is divided into short range and medium range communication technology (Meri et al., 2019). Short range communication technology is used to establish communication among objects that are within limited range. Medium range communication support communication over long distances in healthcare sector.

Confidentiality

It's a common worry when it comes to cloud computing alternatives that the database housed by suppliers is not as safe as that kept on board. Client documentation is deemed delicate, and a strong level of security must be preserved to ensure that such data is only available to those who have been granted permission to do so. Despite the fact that the cloud provides a variety of advantages and protective features, cloud storage is still vulnerable to hacking (Misra et al., 2019). With the growing amount of client records and the growing number of efforts to change healthcare via digitalization, database integrity and access are becoming more prevalent. Furthermore, individuals are also worried about the safety of their information, which underscores the need to sustain high-level security requirements for information protection. Cloud services are susceptible to the same security risks as conventional network infrastructure and are therefore not recommended. Despite the fact that they provide more access control methods and techniques, dedicated servers are nevertheless viewed with suspicion by the medical sector as far as database issues are concerned.

Teleclouds are beginning to appear in cloud computing.

It is becoming clear that the confluence of network connection and the cloud will be a compelling method for providing medical services to distant places shortly. In many nations, most doctors and specialists are concentrated in metropolitan areas and urban areas (Indrakumari et al., 2020). In order to provide modern care centers, only urban regions are equipped with them, abandoning clients in remote regions without assistance. In order to solve this issue, the usage of a telecloud is recommended, which allows doctors and hospital experts to identify and administer clients from a range in actual manner and at a reasonable cost. As medical professionals become more aware of the benefits of telemedicine services, the use of the communication cloud is anticipated to rise in a number of nations, providing significant development possibilities for participants in the medical high – tech sector.

There are problems with uniformity and compatibility.

Among the most essential needs for any medical institution firm is getting insight into patient’s records quickly and easily. In the case of a facility's data migration to the Internet, the information is kept on devices and technologies managed by the provider, which may present some technical challenges (Martino et al., 2016). Platforms and gateways for cloud computing are the most difficult obstacles for companies seeking cloud technology compatibility. Because of a shortage of standards amongst cloud vendors, data exchange across cloud-based tools is limited, resulting in problems with mobility.

Increasing demand for medical and non-healthcare information organization is anticipated, which would help drive the industry's growth forward

Depending on the type of outcomes achieved, the medical cloud technology business may be split into two major classifications: healthcare professional services and pharmaceutical insurer systems (Nomoto et al., 2014). According to the projection, healthcare professional services, which comprise medical record platforms and nonclinical data management, are expected to grow at the highest rate over this time period. Per the survey, the expansion of the market for virtualized of the named alternatives can be ascribed to the positive effects that virtualized of the mentioned solutions provide, like on disk space, effortless interoperability of application domains, application of appropriate techniques, conformance, data management, and assurance.

The cloud infrastructure installation choice is projected to get the largest circulation

The remote patient monitoring industry is classified into the below named categories of network architectures: community cloud, confidential cloud, and blended cloud (Michels& Walden, 2021). Community cloud is the most often used deployment style in medical cloud technology. In the Field of medical cloud technology, the community cloud is by far the greatest often utilized implementation type. According to forecasts, the confidential cloud implementation option is expected to make up the bulk of the economic share. In contrast to giving administrators complete power over their networks, the assumption on private cloud provides a very reliable secure environment. Confidential cloud hosting is an excellent choice for larger organizations that have in-house IT staff who are also knowledgeable about security issues. Furthermore, on premise private cloud allows companies to deploy their own applications while still complying with any regulatory constraints, which will result in increased use in the coming years.

Machine Learning in CC serves a crucial role in diagnosing diseases

Worldwide, breast cancer is a vital cause of death among women. Early detection followed by rapid treatment can minimize the risk of death because of breast cancer. It has been recently noted that machine learning in CC serves a crucial role in diagnosing diseases, but predominantly in individuals staying in remote areas where the facilities of medicines are less. Diagnosis models based on machine learning serve like secondary readers along with assist radiologists’ incorrect diagnosis of diseases. In contrast, cloud-based models can aid support the telehealth services along with remote diagnostics. Methods based on ANN have caught the attention of several researchers for exploring their capabilities for diagnosing diseases. Extreme Learning Machine refers to a variant of ANN having huge potentials as a solution for several classification issues.

Cloud computing services got more critical for creating living surroundings. In addition, CC services can be utilized to monitor patients, older adults, and disabilities within remote or inaccessible towns and villages in several underdeveloped nations, where medical facilities and expertise are never readily present. In such areas, women affected with breast cancer get rendered undiagnosed, and ultimately, it gets late when reaching doctors present to larger cities. Doctors can use CC for diagnosing patients that cannot be reached because they lack financial resources. They can utilize CC for guidance via telehealth along with telemedicine which involves the sharing of several medical data like great-resolution biomedical images and patient video conferences from remote sectors to the other locations, where the physicians along with massive healthcare centers are situated, (Lahoura etal. 2021)

For disease diagnosis and medical image analysis, machine learning approaches are widely utilized in the medical sector. It has various functions like pattern recognition, fraud detection, disease prediction, along image segmentation. Yet, the conventional machine learning methods are never enough for substantial medical databases. Thus, great performance computing gets used in machine learning data to achieve efficient and accurate diagnosis of massive medical data. A subgroup of machine learning is deep learning which relies on learning data illustrations to classify features, along with using supervised and unsupervised machine learning techniques. The technique is advanced, possessing the ability to discriminate data features without man intervention. It has the capability of producing robust and representative characteristic layer by layer in neural networks. Data utilized for deep learning are achieved from various sources with correct data types and significance for developing suitable models for managing data analysis. Typical data analysis models involve clustering, neural network, classification, and other efficient models.

The neural network is a crucial element in deep learning that replicates biological models for communication node distribution and information processing. The deep learning process involves RNN, RBM, AE, MLP, and even CNN. With the functions of storing, handling along with processing are complex for huge-sized medical images, there is a need for great performance processors are needed for processing medical images. Hence, CNN gets used in the medical field for processing massive medical data. It is a feed-forward neural network that aids in modeling sequential data. It also aids in predicting and classifying diseases and decision-making in times of disease diagnosis by using several approaches. Thus, it can aid the clinicians in detecting and characterizing the critical features in huge image series (Deepika et al., 2021)

Home care services in healthcare 4.0

With the elevating numbers of the aging population, there is a rise in demand for home care services, thus transforming aged care at home from open-loop human-dominated models to closed-loop HRS. However, there is the expectation that significant issues are being faced in the emerging interdisciplinary sector, which gets addressed through the enabling innovations originated from I4.0. Healthcare 4.0 is utilized for depicting the gradual rise of the fact that is elevating several innovations, particularly CPS, incubated in the manufacturing sector, are being employed in healthcare. The evolution context elevates quantities of CPS to shape digital healthcare models, including products, services, and technologies involving intelligent sensing, actuation, BDA, AI IoT, Fog, and CC.

There are various features enabled by Closed Loop feedback, such as affective human-robot-interaction. HRI has turned into an important research topic in cross-disciplinary fields of behavioral science, psychology, and cognitive science in the last few decades. It involves both developments of robots with man involvement and the study of how man and robots interact. However, healthcare robots need to communicate with users for performance optimizing. Thus, robots need to effectively recognize, respond and interpret emotions expressed by man, provided such emotions convey crucial aspects of interactions like thoughts and feelings.

The second feature enabled is seamless infrastructure-robot-interaction. Many points’ smart devices and open-loop models have been created to expand IoT and intelligent infrastructures. Enabled by the closed-loop feedback, CPS-HRS integrates each intelligent device in home surroundings to promote and advance seamless infrastructure-robot interaction. Thus, more detailed and abundant data on the condition of infrastructure and surrounding ecosystems' impact on health care can be gathered. Thirdly, there is a feature of Human-Robot-Symbiosis where several advanced robots entered the human workplace with quick advances in robotic innovation. The robots can run alongside a man with particular work without the need for natural barriers. Lastly, there is the feature of collaborative robot’s teleoperation, a promising solution for the absence of home caregivers to the aging population, (Yang et al., 2020)

CPS in healthcare

In quick summary, CPS gets designed for replacing the embedded models. They assimilate current computing innovation with information and communication systems. The CPS combines the microcontroller processing model's characteristics and communication networks with the physics of the whole system functioning in the actual world. Regarding Humaid, the concept of CPS has three critical components in healthcare: computation, communication, and monitoring. The devices have a natural component like sensing along with a networking component for communication. The model is utilized like a collection of sensor data that communicates with controller; CPS is poised to play a crucial role within the healthcare industry. The multiple types of research on healthcare's CPS focus on an actual-time innovative sensor model that monitors and warns of patients' conditions in healthcare. This involves telemedicine models that qualify remote healthcare service facilities and self-controlled remotely functioning service robotics, which aid patients with actual activities. CPSs within healthcare are responsive to users, network model medical devices, and life-critical who cooperatively treat patients in complex medical situations (Malapane, 2020)

How did Fog computing rise in healthcare 4.0

However, the cloud is not favorable for critical applications. The application based on the cloud has various issues associated with significant bandwidth needs, safety and security, and intermittent delay issues. Healthcare applications need real-time monitoring. Cloud can never fulfill actual-time needs. The data gets moved to the cloud and back to the application leads to delay. Such issues are vital to healthcare, where a timely and correct response is required for saving a life. Models of cloud-based enable data from various sites and devices to get gathered, and output is then set to the desired device, leading to response delay and needing incredible bandwidth for massive data. Data safety and user privacy are key significant issues. Such reasons make persons much hesitant to utilize the cloud (Pareek et al., 2021)

Despite multiple drawbacks of the CC paradigm, primarily associated with communication between end devices and datacenter hosting cloud services, specifically in latency, cost, bandwidth, and connection availability, all contribute to limiting uses of CC. The proliferation of pervasive mobile devices worsened the situation, considerably challenging the cloud paradigm. Indeed, in multiple contexts, the cloud never meets each requirement of the application. Various concepts, terms, along with expressions have been coined for solutions and lead to the rise of fog computing for transferring some CC services to edge network, close to devices of the user along with possibly partially depending on users' device resources along with distributing the load among end devices and old CC datacenters along with bringing local-term safety, low-latency rates along with faster responsiveness while aiding to promote performance scalability for the entire system.

Fog computing promotes on-time service delivery and significantly mitigates several problems associated with the cloud, like the cost overhead, delays, and jitter while information gets transferred to the cloud. It also aids user mobility, interface, resource heterogeneity, and shared data analytics to address the needs of shared applications needing low latency. In addition, it eases the management along with the programming of storage, computing, and networking services between end devices and data centers. Fog computing refers to a powerful tool for supporting the decentralized along with intelligent processing of the data volumes produced by IoT sensors used for integrating cyber and physical surroundings, thus aiding the IoT to attain its vast potential (Aceto et al., 2020)

Mobile Computing in Healthcare

When there is an issue in developing nations in the sector of infrastructure innovation, there is a rising need to use mobile cloud computing, which remains a modern concept, along with the concept of e-health and the applications and needs for the application. Mobile health is one of the critical issues to be addressed, having variants of entry health services among them poor health infrastructure in most nations and existence of deficiency in man resources working in the health field and high cost of health services that are limited to financial resources availability. By comparing mobile health with the computer and network e-health services wired, mobile health services allow users to have access to health services with much more ease and comfort regardless of the place and time. Mobile health refers to use concerning cell devices like many smartphones, mobile applications, network and individual sensors that collect information from the man, to give services health. One of the key benefits of mobile cloud computing, giving it the popularity, is minimizing the power consumption and augmenting manipulator practice through expanding serious resource runs from mobiles to clouds. The most common complaint about the paradigm is the short battery life and the limited supply and capacity of storage. Mobile CC has familiarized offloading, where data is kept, and additions get finished in remote cloud-like substitute of the mobile device. The merit of the method involves green cloud surrounding and energy-efficient mobile network, Ali et al., 2018)

Regardless of the merits, MCC poses, one of the top difficulties in using MCC is the incorporation of security along with the privacy of classified information. Currently, MCC is extensively included in cloud based-health monitoring, but because of the absence of accurate security, it is getting less attention as it needs. Such challenges need immediate addressing to make MCC more favorable. Security of HI is one of the iterative procedures and changes to healthcare environs. By employing new schemes to promote the quality and effectiveness of HI, it is imperative to reconsider HI's security practices and policies. Recognizing threats and securing HI is one of the demanding challenges in healthcare.

However, there is the MES scheme which is a modular symmetric cryptographic algorithm. Utilizing the scheme, the first module with entropy-based Key production is actualized on MCC client-side along with the second extender module intended for extension and compression of Health records before transferring data to the cloud (Yuehong et al., 2016).

The rendered modules are done on crypto-cloud, and the multi-cloud-based storage gets carried out. As a result, the modular scheme at various layers drives us to multi-layered modular security of records at the cloud in healthcare. Through this approach, even cloud service givers are incapable of approaching HI because each giver approaches the enciphered health record version. This way protects the HI from insider entry just as outside access. The various features of intended schemes in the MCC surrounding area ensure HI's confidentiality against a hacker or the third parties, complete control of patients to their health data, and unwanted trials to access HI can get restricted. The next feature is that it gives a requirement-centric method against ensuring HI confidentiality. There is also the feature of only patients having entry to HI. In addition, based on needs can be distributed to others which involve the experts and specialists. The last key feature is that layered modeling with modularity can support against the attacks of intruders to HI, Shabbir et al., (2021)

Due to the industry's dependence on solution vendors to fuel category development, the Medtech segment

An industry for medical cloud technology is segmented into two groups depending on the elements that are utilized in the system: equipment and operations. According to projections, the hospitality industry will grow at the highest rate of any comparable field over the projected timeframe (Alagumalai et al., 2019). This phenomenon may be connected with the recurring structure of activities, including orientation and learning, setup, system upgrades, consultancy and servicing, and the high development level of this industry. The emergence of software packages and the required additional to ensure application interoperation are anticipated to boost the demand for a broad variety of programs with significantly extra others.

This costing system is composed for the largest share of the economy according to data from IDC.

In estimating the expansion of the overall medical cloud industry, a component to consider is the billing system that may be separated into two major subgroups: remuneration plans and flash fee structures (Tanjung et al., 2019). Whenever it pertains to prepaid cards, the payroll option accounted for the largest share of the industry in the previous years. The notion that the remuneration strategy, often referred to as the convenience capitalist structure, allows medical professionals to take advantage of the most up-to-date technology technologies while retaining low operating costs could contribute.

Standard frameworks for CC in healthcare

Compliance with HIPAA is essential in each case where the patients' individual information gets shared, like clinical research, along with continuity of care is needed. All the efforts entry patient information needs to be within the scope. Through the CoronaVirus Aid, Relief, along with Economic Security Act, some HIPAA regulations applied to telehealth get relaxed, along with telehealth coverage for Medicare got expanded. Consequently, patients' entry to medical services elevated, along with medical institutions, can enhance infection control, reduce general risk to public health, and provide needed medical services. HIPAA regulation safeguards the privacy of personally identifiable health data and ensures lawful use and dissemination of health data to promote great-quality health care.

The HITECH Act, created by OCR of HHS, places Bas under HIPAA Security Rule compliance and HITECH Act's security and privacy provisions. From consecutive announcements and statements between April and February in 2003, HHS emphasized HIPAA's correct functions instead of its dysfunctions, listing several social benefits obtained through it. HHS believed that through harnessing information innovations, HIPAA could ensure correct privacy security and maintain the common-sense balance between protecting patients' privacy and giving the best quality care (Yuehong et al., 2016). In addition, HHS affirmed that the function does not interact with physicians’ capability of treating their patients along with enabling vita public health projects like surveillance of outbreaks and reporting adverse drug event (Kim &Josh, 2021)

With the rise and widespread deployment of cloud computing solutions, HIPAA-covered entities, along with business associates questioning how they can take merit of CC while adhering to regulations security and privacy of electronic PHI. This guidance aids such entities involving cloud services givers in clarifying HIPAA obligations. The following guidance is concerned with cloud resources given by CSP, which is an entity legally distinguished from a covered entity considering the use of its services. The HIPAA Security, Privacy, and Breach Notification Rules create vital safety for PHI information that involves limiting the usage and disclosure of such data, safeguards from inappropriate use and disclosures, and personal rights with concern to health information. The covered entity, along with business associates, needs to comply with applicable provisions of rule in HIPAA. A covered entity is a health plan, a health caregiver, or a clearinghouse that conducts specific billing and payment associated transactions electronically. The business associate refers to an entity, other than members of the workforce of the covered entity, performing activities or functions on behalf of covered entity involving creating, receiving, maintaining, or transmitting PHI on behalf of other associates in business ("Cloud Computing", 2021)

Conclusion

According to predictions, the Software as a Service model will offer the most significant solutions in the E-Health sector. The industry might well be classified into three categories based on the subscription service that is being used: SaaS, Iaas, and Paas. Several benefits over on basis systems, like safety, reduced cost of operation, quicker proposed action, and fewer initial operating expenses contributed to the SaaS model accounting for the biggest portion of the market. The use of cloud technology is becoming more popular among medical providers and clients equally, in particular to fulfill their requirements (Serrat, 2017). That’s why cloud technology is an inter-service that can handle an unlimited number of clients while also enabling data at any point in the world, which makes it particularly appealing. Because a supplier or a wireless carrier maintains it, this solution may assist in minimizing upkeep expenses while also increasing the effectiveness with which facilities are used.

The following study aims in fulfilling the gas via the proposed study model. It suggests a framework that studies the key drivers along with challenges in e-health. It has been suggested that cloud computing is the result of two main trends in IT. The first trend is that cloud computing gives efficiency. Healthcare companies can benefit from such features by minimizing the capital expense linked with the on-premises deployment of the data center. Datacenters for hospitals are very expensive due to the lifesaving nature of the companies and the necessity for the data center to maintain the mission. To finish this, assurance of excellent availability along with zero downtime of the services is required. Zero downtime and high availability are complex technical issues needing several resources, thus an expensive option. In the non-cloud scenario, companies tend to have several ranks of redundancy along with excellent availability accompanied by disaster recovery. This can include several data centers operated by others to obtain service availability and compliance with government regulations.

The second trend is that CC, as claimed, gives IS along with business agility which is cloud services hallmark. CC gives companies with functions and features for improving their business operations. Excellent availability along with disaster recovery characteristics of CC is crucial for healthcare and enables quick recovery. The service providers can offer production and prebuilt ready tools and platforms, increasing the development speed of the application in the organization. These can be combined with previous systems via correct-documented API and provider support, Al-Marsy et al., (2021).

Healthcare managers and professionals are searching for strategies to elevate health information management flexibility, efficiency, and cost-effectiveness. CC was a new computing model with promises of more flexibility, more efficient, and inexpensive IT services for users. It has been claimed that the model is an excellent opportunity for healthcare settings to enhance information management. Furthermore, when organizations regard moving to cloud services, it requires examining and addressing new model challenges along with assessing the capabilities for achieving the goal along with identifying strategies for the implementation ("Cloud Computing for Health Information Management", 2021)

Chapter 3

Health care main aim is to improve our health by diagnosing, treating and preventing diseases. In the process of ensuring that the above activities are achieved big data is generated each day. In health care big data analytics shifts data management and its technique from structured to semi structured or even unstructured data and from a static terminal environment to a ubiquitous cloud-based environment. Big data analytics in health sector uses rapid increase in data volumes to come up with patterns and trends in the inherent complexity of the data and to come up with solution or make smarter decisions. In real sense big data analytics can assist in improving the quality and reduces tremendous cost of healthcare delivery. Cloud computing is the ultimate choice for big data and big data analysis in health sector. As we know cloud computing brings about advantages such as flexibility, security, parallel processing and virtualization of resources.

Data collected in healthcare for analysis

In health care some of the big data collected for analysis via cloud computing includes data from patient from electronics health records, computerized physician order entry system, clinical decision support system, medical services and sensors. Other type of data collected which is of less patient relation includes emergency care, new feeds and research articles. This type of data is usually tremendous become it volume is huge, the data is diverse and it requires higher analysis speed (Aceto et al., 2020). Usually, this data collected from healthcare is huge and it synthesized by 7Vs which are:

Volume

The data volume is that huge making traditional and new data types to become a storage problem, this huge data volume also affects complexity of data analysis. The volume of data in healthcare is increasing each day due to conversion of existing paper data form to new electronic emerging form. Examples of these new forms include 3d images and genomics. These new forms are cloud based and they offer effective collection, storage and management of huge data volumes.

Variety

Semi structured and unstructured data is being generated each day from new channels and emerging technologies such as social media and internet of things. In health sector the semi structured and unstructured data is being generated in continuous manner through information movement from paper medical records to EHRs and electronic media records. It also includes data such as reading from medical devices, some clinical data accounting which are electronic and bills and statistics used to find out the possibility of risk occurrence. According to Ali et al., (2018) some of ways in which unstructured data can be found in health care includes in paper medical records, prescriptions, notes which are written via hands, x rays and many other images that may be taken. Other ways in which data used in cloud computing is generated in healthcare includes from fitness devices, genomics, research and social media.

Velocity

This is all about speed of data generating, retrieving, processing and analyzing. The velocity of data generation in health care is increasing each day due to real time generation algorithms. Request combining data flow with business activities and process of decision making. According to Lo’ai et al., (2016), some of the data generated in health care can be static and it includes paper medical records, x-rays the other can be medium velocity or even real time for example operating room monitors. Creating of up-to-date results is so crucial for example in clinical decision support it assist in making right time decisions in a rapid manner.

Veracity

Veracity is about accuracy and compliance of the data. This is difficult especially for data in health care which comes in form of big data from numerous sources. Veracity in health care affects patient safety due to risk of low-quality data.

Variability

This is about how the data can be understood. Let for example look at sophisticated algorithm which is so essential in getting the real and correct meaning of social media comments which can be a data type in health care.

Visualization

It all about readability and accessibility of the data presentation and it requires numerous spatial and temporal parameters and at least a relationship between them.

Value

In health care efficient tools and skills are so necessary in analyzing huge amount of data to come up with exact results and make an improvement in outcomes at health sector.

Clinical data in health care

According to Lo’ai this data type is collected during the course of ongoing patient care or as a part of formal trial clinical program. This data is of much use in cloud technology of health care and it exist in forms such as electronic health records, administrative data, claims data, patient data, health surveys and clinical trial data. Electronic media record is the purest form of electronic clinical data since it obtained at the point of care of the health facility. In clinical data the information collected includes administrative and demographic information, diagnosis, treatment, information on drugs prescription, test carried out in a lab, hospitalization data and insurance on patients. Administrative data is all about hospital discharge and this data type is reported to government agencies. Claim data in health care give details on billable interactions between the insured patient and health care delivery system. This data type can be either of outpatient, in-patient, pharmacy and enrollment and it of much use in cloud base analysis. In cloud computing data on health survey offers accurate evaluation of population health, national surveys and the prevailing national surveys. Clinical research dataset in cloud computing is available through national or discipline specific organizations.

Methods used to collect the data for analysis

Data from health care which is needed in cloud computing needs to be collected. This data though does not flow along the health sector in a cohesive standardized way. Methods such as conducting health survey, administering enrollment and bill records, medical records can enhance data acquisition for cloud computing. Some of these methods are traditional and uses a lot of paperwork however they can become so reliable in cloud computing when converted to electronic form. To enhance this process a good computing infrastructure should exist and be set in the right manner in the health sector. The infrastructure should consist of the necessary hardware and software settings (Aziz & Guled, 2016). Let look at a scenario of collection of data involving ethnicity race and language in hospital. At such case cloud computing together when combined with health information technology can assist in improving on data collection by incorporating individual personal health record and later utilizing them electronically in electronic health record and other data systems. The data contained in electronic health record includes on medical imaging, socio behavioral and data on environment.

Electronic health records benefits to a health care

Electronic health records offer several advantages to health sector and the first one is that it has enhanced healthcare professionals to have improved access to medical information and history of a patient. It has information on medical diagnosis, prescriptions, data concerning identifiable allergies and information regarding lab tests. It reduces the time needed to recognize and treat several medical conditions. It assists in reducing logistical errors hence reducing number of drug allergies by eliminating errors in medication dose. By use of cloud computing and related technology healthcare professionals can now access over web based and electronic platforms to make an improvement in medical practices significantly by use of automatic reminders and prompts concerning vaccination, abnormal screening in the lab, cancer screening and other checkup which are done periodically (Dang et al.,2019). Data acquired through cloud computing electronically enhances communication among multiple health care providers and patients. This comes about due to less paperwork involved. EHR enhances faster retrieval of data regarding the quality of the healthcare. This is of much benefit to employee health insurance programs and can increase the cost of health insurance benefits.

Some other methods of data collection for analysis in health care and which engages cloud computing includes use of internet of things, use of electronic health records, electronic media records and means such as phones.

Insights from analysis health care data via cloud computing

According to Alexandru et al., (2016) use of cloud computing in health sector is more than just storing data and cloud architecture since through it now healthcare providers are gaining more efficiency, optimized workflow and lower associated cost in healthcare delivery. Analyzing of big healthcare data by cloud computing is advantageous to both the patients and the healthcare providers. It assists in cutting down the operational expenses and at the same time it allows health care provider to offer high personalized health care. The analysis also results to improved patient outcomes by the clouds using amp up patient engagement with their own health plans by allow their own access to healthcare data.

The following factors can be contributed to cloud computing data analytics:

Access to high power analytics.

By application of big data analytics and artificial intelligence algorithm on data stored on cloud patient can power up medical research. A cloud enhances processing of large data set to use in health sector to be easier and more feasible. It also assists in coming up with a more personalized care plan for patients especially on individual level. Cloud computing data analytics ensures that all data concerning the patient are stored in right manner and none is missing. It allows easy retrieval of relevant information regarding the patient.

Patient owns their data.

` Cloud computing gives patient control over their health. This is possible by boosting their participation in decisions concerning their health. This leads to informed decision making by acting as a tool for patient education and engagement. It allows easier retrieval of patient records and medical images. Back up in cloud computing system makes retrieval of data to become simpler.

Allows telemedicine capabilities.

Combination of cloud computing with healthcare improves healthcare related functions such as telemedicine, post hospitalization care plans among others. Through cloud computing access of health care through telehealth becomes so possible (Aceto et al., 2020). Apps on telemedicine enhance convenience of health care delivery and at the same time improve the experience of the patient.

Cloud computing in health sector of developing countries

Cloud computing gives about better potentials to make changes in the way healthcare sector functions in Iraq. Expert nowadays is considering cloud computing as the new wave of web in the health sector. Government is playing a key role in development of cloud computing across the economy especially in health sector. Cloud computing offers several advantages when compared to other type of technology used in healthcare especially the tradition ones. Some of the advantages associated with cloud computing includes reduction in cost, storage increase, automation level increase, standardization, high flexibility levels and increase in employee’s mobility. Most healthcare sectors are still dealing with traditional computing (Shepherd, 2019). Most of the factors that can explain the current state of computing in health sectors includes lack of information technology expertise in government health sector which affects the availability and quality of information technology services being delivered, the other factor is underutilization of information technology resources is spread through.

According to Shepherd (2019) government healthcare secures hardware and software and end up using just half of their capacity and this leads to capital wastage, each health care has its own technology and platform hence making it so hard to achieve interoperability with other organization in medical sector hence coming up with information technology solution becomes a complicated thing. Other challenges associated with adoption of cloud computing in health care includes lack of users to near ubiquitous internet access, cloud systems must be equivalent to or be better than current standalone system and barrier between government institutions which should be opened and security and privacy of user’s data must be defined clearly and protected. For developing countries adoption of cloud computing in health sector is related to a lot of problems. One includes lack of political leadership to push adoption of such technology. most developing countries perceives cloud computing technology as a disruptive technology that is not yet mature with the lack of industry specific conformity to standards.

In introducing of cloud computing in health sector it may be faced with high level of related risks and cost. In adopting cloud computing in health sector two technology are taken into account which are diffusion of innovation and technology organization and environment framework. Expert in cloud computing and healthcare emphasize in the need to combine the two theories when studying and adopting this technology in order to eliminate any possibility of being ignorant on some aspects which could create a big effect on strategy used for adoption.

Innovation characteristics

According to (Kadhum & Hasan 2017) the theory of diffusion of innovation explains why, how and what rate new technology and ideas spread throughout the culture. This theory in adopting cloud computing in health sector is based on characteristics of technology and perception of user in the system. This theory views innovation to be communicated throughout certain set of channels over certain period of time and within a social system. In simple this theory is all about characteristics that affect adoption of innovation and they are relative advantage, observability, compellability, and compatibility and trial ability.

Relative advantage

This is a key factor making health sector to switch into cloud. This is all about how the new technology being considered to be better than the old one. It all about the measure on how the new technology can bring some benefits to the health sector. In this perceptive cloud computing is considered to be better technology than the traditional ones in the health sector (Kadhum & Hasan 2017). Cloud computing technology gives health sector opportunity to respond to new needs in healthcare so fast. Relative advantage is also viewed in time saving perspective.

Complexity in health sector due to cloud computing

This is the measure on how innovation is perceived to be relatively difficult to understand and use. For example, in health sector people are already used to a certain routine and system. Hence upon adoption of cloud in medical sector training and extra efforts are needed to get the new technology into the health sector. Lack of expertise and new technology expert creates a lot of problems (Keshta & Odeh 2021). Complexity negatively influences adoption of cloud in the health sector.

Compatibility

This is all about how innovation fits with existing values, previous practices and current needs. Compatibility of cloud with existing infrastructure is an essential factor to consider when one is deciding to adopt cloud in healthcare sector. The cloud used in healthcare should be compatible with the existing infrastructure in terms of solution it’s supposed to offer. If the cloud technology being adopted in health sector is not compatible changes can be done to enhance compatibility. High compatibility will positively influence cloud adoption in the health sector.

Materials and Methods

Security concern in cloud computing.

When a health care sector moves to the clouds new layers of complexity for data securing are added hence affecting adoption decision. The healthcare security team should ensure once cloud computing is adopted in its medical services patient data are protected. Necessary infrastructure should be there to enhance security. Hence security concerns will negatively affect advantage gains of cloud computing in the health sector (Vithanwattana et al., 2017). In adopting cloud technology in the health sector, it’s so important to look at technology readiness and it includes infrastructures and information technology human resources. This measures the readiness of health sector to adopt the new cloud computing technology. Technology readiness positively influences adoption of cloud in the health sector.

Cloud computing as a modern technology has brought various benefits to the industry of the health of Iran. In Iran the study was conducted through qualitative approach and through in-depth interviews with an aim to identify factors affecting use of cloud in health system of Iran. In Iran cloud computing is a novel phenomenon that why qualitative method is the ultimate approach method so that to understand the underlying issue in more details. Series of interviews were carried out and the people involved had work experience in field of information technology and health cloud computing (Aceto et al., 2020). Selection of people to engage in the study was done through snowball sampling method and sustained to reach diffusion. The interview was enhanced by interview guide who was designed by researchers and five open questions were used to collect the required necessary information. The mode of interviewing was face to face and by telephone interviews.

According to Aceto et al., (2020) due to the fact that interviews were accomplished through snowball sampling methodology at interview end, interviewees had to introduce other individuals with at least some experience in health and information technology. Implementation of texts was via word 2013 software and research team studied them carefully after every interview. To enhance scientific accuracy of data member checking was done regularly. This also increased the quality control of the data. More study was conducted quantitatively to lead to a better understanding of the subject.

Results

Results obtained are in form of technical, organizational, economic and security advantage.

Technical advantages

One of the technical advantages is reducing the time of software installation and selection using the cloud facilitating data mining and analysis of health data using cloud forecasting and planning for the future in health system. The other advantage is finding demographic patterns with high resource storage and analysis in cloud computing (Alexandru et al., 2016). Other technical benefit includes high accessibility, basic capabilities and feature of cloud elasticity and flexibility upgrade of information technology.

Organizational advantage of using cloud in health of Iran

According to Dang et al., (2019) increase in the efficiency of information technology related processes in hospitals time saving and quick handling of system. Accelerating hospital services since there would be no need for full time specialist in hospital. Other benefits from the study include increase in high level capabilities.

Economic advantages

Hospital expenses will reduce, support of high rank organization of the cloud due to economic and technical benefits. According to Alexandru et al., (2016) for small hospital cost effectiveness of clouds will increase, no need for employment of internal staff for maintenance and support. There will be reduction in direct financial and hardware management expenses in the cloud.

Security advantage

According to Rajabion et al., (2019) an increase in data security in clouds due to data concentration and definition of security protocols in each layer. There would be an upgrade in identification and security.

Cloud computing overall benefits to the health sector

According to Darwish et al., (2019) use of cloud computing in healthcare offers a lot of benefits when compared to the use of in-house client-server system. Cloud computing offers economic, operational and functional advantage. The economic benefit includes cost flexibility and reduction in cost. In cloud computing heavy capital expenditure are avoided due to the fact that information technology resources are acquired in demand and their mean of payment is through operating expense. The cost of cloud computing also includes cost of staff resources needed to deploy and maintain information technology resources (Darwish et al., 2019). The need for extra healthcare provider skilled information technology resources and the cost related are reduced when using cloud services. This occurs mostly when using IAAS and PAAS platforms but even during the use of SAAS solution cloud service provider is under the whole responsibility and control.

Operational perspective and advantage of using cloud computing in healthcare occurs in that there is ability to offer scalability and ability to adjust to demands in a rapid manner. Cloud services offers better security and privacy for healthcare data. The better security comes about in that cloud providers data center are highly secured and protected not only from outsiders but also from insider threats. This is possible through administrative, physical and technical methods that are under control of an expert in security. Use of cloud services in health sector enhances offering of sophisticated security controls. These security controls include encryption of data, fine-grained access controls and access logging. Use of cloud services also minimizes the need for scarce information technology security skills within the medical sector (Aceto et al., 2020). The providers of cloud services functions in a manner that they have all needed information technology skills and the cost of those skills is spread across many customers.

In healthcare functionalities are well enabled by use of cloud services. The information technology system used offers potential for broad interoperability and integration. The standards used by cloud services in healthcare follows some certain protocols and the cloud services are based on the internet. Clod services enhances sharing of information in an easy and secure Rajabion et al., (2019). By use of cloud in healthcare rapid development and innovation is enhanced and this occurs mostly for mobile and internet of things devices. Use of clouds enables remote access to data and applications through the internet this is made possible by use of wireless systems and wired ones. This remote access can be from anywhere and at any time. If there is a need for access to a much larger ecosystem of health providers, payer, life sciences and information technology partners then cloud computing is the ultimate choice in the health sector.

The ultimate benefit of using clouds in health sector is wide new ranges of capabilities that clouds offer. These better offered services increase the necessary opportunity to extend the available capabilities in health organization staff, with an aim of implementing improved ways of working and with an aim of offering new services to patients. Cloud services have the ability to support healthcare provider staff cognitive capabilities hence mitigating medical mistakes and reduce patient adverse events. These cloud services include intelligent business process management suites and case management framework. Capabilities associated with cloud computing in health sector assists in facilitating personal health maintenance, improvement in diagnose of diseases, acquiring better cases outcomes and assist in making transformation from volume to volume-based care.

Guidance for leveraging cloud computing in healthcare

In order to ensure successful deployment of cloud-based healthcare solutions some steps should be taken into and to start with is coming up with business case for cloud computing (Vithanwattana et al., 2017). examining the most appropriate cloud deployment and service models, make ensure all security and privacy requirements are addressed, integrate with existing enterprise systems, make negotiation on cloud service agreement and monitor key performance indicators and lastly manage the cloud environment.

High value cloud computing services for healthcare

There are various cloud services offered in the healthcare and they cover wide range of capabilities. One of the services offered is population health management. According to Vithanwattana et al., (2017) in population health management cloud and big data services assist in tracking diseases hence informing the population on the areas where risk exist. HealthCare’s can come up with the infrastructure necessary to support these services by minimum cost by utilizing cloud computing. The other offered service is care management support and healthcare are utilizing cloud-based practices management, medical records and medical image archiving solution and the solutions offers cost effective implementations and this offload tasks from hospital information technology department hence making this department to focus on other tasks within the health sector. By use of cloud diagnostic support are offered and this occurs by organizations developing new SAAS products and services that assist in coming with expert at health sector at a lower cost. For faster screening of diabetic patients combined automated image analysis tools with user friendly telemedicine are used (Vithanwattana et al., 2017).

Through use of cloud services in health sector image handling services are offered. This type of services enables healthcare organizations to make a scale on storage services at an affordable price. Cloud computing enhances medical practitioner assistance in the medical sector. Through the use of cloud services medical practitioners are able to search huge amount of data hence coming up with more reasonable treatment plans. Some of the existing tools includes flatiron oncology cloud suite of tools for oncology and by use of this tool patient utilizes offered services hence exploring their medical issues and collaborate with those treating them (Amron et al., 2017).. The other service is patient connectivity to the health service providers. Another service is data distribution service that enhances exchange of data especially key health related data between organizations.

Discussion

Based on findings in the research very soon cloud computing will be the main things in health center of Iran. Currently most public and private hospitals in Iran are equipped with hospital information system and electronic health program is followed and established by health ministry. Cloud computing has offered better opportunity for analyzing the produced data in health system by offering storage and computing resources (Dang et al., 2019). This has created more possibilities for data mining and analysis of patterns from the health data.

Contexts influencing adoption of cloud technology innovation process in health care

There are three context influencing technology innovation process and to start with is technological context. According to Ahmadi et al., (2019) this context includes the technology currently and internally being used within the organization and in addition to external and obtainable ones which are accessed by the organization. The other context is organizational context and it all about organizational structures which includes size, scope and managerial structure. When it comes to environmental context it’s all about factors relating to the environment in which organization exists and operates. The environment can be industry and competitors (Sivan, &Zukarnain, 2021). The three contexts can work as either constraints or opportunities for clod computing technology innovation in the healthcare.

Conclusion

In deduction cloud computing has impacted health sector in a positive manner. The cloud computing process in health care is possible by establishing the necessary infrastructure that consists of the necessary software and hardware tools. Some of the data collected in health care via cloud computing includes data on patient from electronics health records, automated physician order admission scheme, clinical decision holds up system, checkup services and sensors. Other category of data collected includes emergency care, new feeds and research articles. The methods used to collect this data are in electronic form and they include EHR and EMR. Some methods of data collection are in non-electronic form whoever once data is acquired it converted in form understandable by cloud computing technology. The data analyzed through cloud computing is of much use in giving maximum health cover to patients and it assists in helping patient make informed decision concerning their health and in things such as telemedicine capabilities.

Adoption of cloud computing in health sector will continue to evolve. The evolution includes expanded usage of healthcare internet of things devices, storage and analysis of vast amount of healthcare information among others. Cloud computing facilities application of various technologies that includes big data analytics, cognitive computing, mobile collaboration and exchange of information with an aim of accelerating delivery of advanced healthcare solutions. Hybrid cloud deployment offers healthcare providers the flexibility necessary in deploying workloads and data based on business related risks.
