Cloud Computing Services

Cloud computing services mature both economically and technologically and play a more and more extensive role in the domain of software and information systems engineering. SaaS offers advantage for both service providers and consumers. SaaS is faced with the question of appropriate techniques applying at early phase of Requirements engineering of producing system. The paper highlights two traditional methods namely i* and VORD belonging respectively to Goal oriented Requirements Engineering and Viewpoints approaches. The approach proposed try to dealing with the requirements elicitation in the context of Software-as-a-service SaaS. So, the approach benefits from strengths of both VORD and i* models and propose a combination of them in a new approach namely VORDi*.

Cloud Computing Services

Change is endemic in modern business competition. In an age of globalization, with the rapid development of Internet technologies, changes occur at a much faster pace, and are also more unpredictable. Being agile in a turbulent environment has been ranked highly by executives in surveys of business issues conducted in past five years. Today nearly all organizations rely on information systems (IS) to operate. Agility in IS is critical in achieving overall agility in business. However, despite the interest from the practitioner community, IS agility (sometimes termed IT agility) in academia has received limited recognition and represents an under-researched area. The recent adoption of cloud computing services has presented a major change in the way IS are delivered, in the hope of creating more agile and responsive IS. However, whether or not cloud computing, as promised by the providers, increases IS agility, is still unclear. This research aims at providing a conceptualization of IS agility based on research to date, and examining how cloud computing might facilitate such agility. Based on a literature review, cloud computing services (IaaS, PaaS, and SaaS) are analyzed against multiple aspects of IS agility. Only IaaS is found to have the potential providing consistent agility, whereas agility at PaaS and SaaS levels is more determined by human/organization factors. Lastly, suggestions for businesses and directions to future research are proposed.

Positivist Approach

The rapid increase in investments for computerised systems is a major concern for all health organisations. Questions about these investments arise as information technologyis only one of the areas that are competing for a finite amount of resources. There is also some concern that some of the failures of information technology would have been detected if proper evaluation of information systems were conducted. The state of the art of evaluating information systems shows changes from a very positivist approach tomore comprehensive approaches that would incorporate multiple methods. This paperpresents an assessment of the techniques and methods for information systems evaluation, followed by an application to a case study in community health to illustrate the value of the contextualist approach to evaluation. The paper argues for the use of longitudinal, contextualist approaches to information systems evaluation if decision-makers seek to improve the situation of information systems in the health industry.

Patient Side

With cloud computing (CC) becoming popular in recent years, variety of institutions, organizations, businesses and individual users are creating interest. They are adopting the technology in order to take advantage of shared web applications, low infrastructure cost, utility and distributed computing, cluster computing as well as reliable IT architecture. In the area of health, Cloud Health Information Systems (CHIS) play a key role not only on the healthcare businesses but patients as well. On the patient side, CHIS aid in sharing of medical data and health information, timely access of critical patient information and coordination of clinical services. Patients, who continue to demand for instantaneous and quality healthcare services are now able to access the services from experts even when they are not necessarily in the same physical location. This is being aided by proliferation of telemedicine through hosted cloud architecture. From the business perspective, CC has helped to cut down operational expenses by way of cost-effective clinical information system infrastructure through the implementation of a distributed platform. The platform has therefore saved businesses millions of dollars that would have gone to infrastructural and human resource investment. Even with these immense opportunities, cloud computing uptake has been serious inhibited by the privacy and security concerns. Due to the sensitivity of personal health information, businesses and individuals are apprehensive when it comes to adopting the technology or releasing the data to the cloud. This study is a results discussion of an enhanced model for attainment of data privacy on the cloud through use of multi factor authentication.

Hierarchy Process

Cloud computing has become a popular topic for exploration in both academic and industrial research in recent years. In this paper, network behavior is analyzed to assess and compare the costs and risks associated with traditional local servers versus those associated with cloud computing to determine the appropriate deployment strategy. An analytic framework of a deployment strategy that involves two mathematical models and the analytical hierarchy process is proposed to analyze the costs and service level agreements of services involving using traditional local servers and platform as service platforms in the cloud. Two websites are used as test sites to analyze the costs and risks of deploying services inGoogle App Engine(GAE) (1) the website ofInformation and Finance of Management(IFM) at theNational Chiao Tung University(NCTU) and (2) the NCTU website. If the examined websites were deployed in GAE, NCTU would save over 83.34% of the costs associated with using a traditional local server with low risk. Therefore, both the IFM and NCTU websites can be served appropriately in the cloud. Based on this strategy, a suggestion is proposed for managers and professionals.
