Both information systems and information technology infrastructure have been incorporated into business procedures for at least two decades. In the initial development of information technology, organizations which greatly invested in information technology infrastructure achieved strong growth in market shares and returns. Given that IT is now the core of businesses, nearly all organizations own their own IT infrastructures to manage their daily business activities. In case of malfunctions in the information systems, the regular business proceedings shall be really interrupted. Though the majority of companies are not IT companies, they have to invest a great share in IT so as to run their business operations smoothly (Chou & Chou, 2011).
Information technology has turned into a necessary infrastructure which organizations need to have; however, it does not essentially offer strategic benefits for business. According to Carr (2003), the growth of the power and ubiquity of information technology has relatively undermined its strategic significance. He made a comparison of the status of information technology and electricity. Both are significant for business' survival but neither offers more strategic values for business. Information technology is now a utility for many organizations, just like electricity. The rising increase in the use of the internet has resulted to progression in internet applications. The work and lives of individuals are greatly integrated into the computer network. Presently, the Web is not just a means of communication but also serves as a platform for business and society. To get to the vast number of users or likely users, organizations need to supply their contents and business procedures online. This recently established trend has led to increased demand for distributed computing power that also triggers a new paradigm- cloud computing.
Cloud computing is a means for organizations to supply their contents and business procedures online with the flexibility of computing resources (Armbrust, et al., 2010). From a business outlook, cloud computing is an on-demand access to virtualized information technology resources which are housed by the third party, utilized by others, easy to use, paid for through subscription, and accessible via web (Brynjolfsson, Hofmann, & Jordan, Communications of the ACM). The offering of cloud computing has presented organizations with opportunities of reviewing their IT infrastructure. Given that various cloud computing dealers are capable of providing extendable IT sources founded on subscription, cloud computing could be regarded as a utility model. With the pay-as-you-go design, organizations consume IT resources just like they consume water or electricity.
Cloud computing comprises of both the applications supplied over the internet and the hardware and systems software in the information centers which offer those services These services are known as a Software as a Service (SaaS). Additionally, cloud computing offers two or more kinds of services; they are Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). With the major advances in Information and communications Technology (ICT) in the last half century, there is a possibility that computing shall one day be the fifth utility (Sasi & Larance, 2014).
Information system analysts normally develop information systems founded on the differing activities in the system development life cycle (SDLC). These particular system development activities are founded on the presumption that information systems shall be developed in-house. Due to cloud computing, some new system development activities require modification or renewal. The aim of this paper is discuss how system development activities require to be altered to respond to the surfacing of cloud computing model together with the concerns that are associated with applying cloud computing model.
Cloud Computing
Cloud computing is basically a new platform of computing whereby software and hardware are supplied to users in a way which resembles the way utilities like electricity are supplied into households. The phrase cloud originates from the utilization of a cloud image which symbolizes the internet or a large networked surrounding. In cloud computing, nonetheless, cloud does not simply only entail routers, servers, and data pipes; it also entails offering capabilities and services to develop application (Hartig, 2009). The cloud computin phenomenon is still evolving. Cloud computing industry entails various levels of dealers as well as various kinds of services for varying market functions. Therefore, it is difficult to exactly describe cloud computing. United States "National Institute of Standards and Technology" made an effort to describe cloud-computing as being a model for permitting suitable, on-demand network access to a common pool of configurable computing resources (like servers, applications, and networks) which can be quickly provisioned...
This approach to defining a performance-based taxonomy will also allow for a more effective comparison within industries as well. All of these factors taken together will provide enterprise computing buyers with more effective foundations of arguing for more thorough measures of application performance. The net result will be much greater visibility into how cloud computing is actually changing the global economics of the enterprise computing industry. III. Final Report: Introduction The foundational
Cloud Computing as an Enterprise Application Service Reordering the economics of software, cloud computing is alleviating many of the capital expenses (CAPEX), inflexibility of previous-generation software platforms, and inability of on-premise applications to be customized on an ongoing basis to evolving customer needs. These are the three top factors of many that are driving the adoption of cloud computing technologies in enterprises today. Implicit in the entire series of critical success
Cloud Computing Benefits As cloud-computing starts to take hold, a number of significant advantages have turned out to be evident. The first one of these, and perhaps the most important, is the costs. The cloud claims to decrease the price of obtaining, providing, and sustaining computing power, a gain of specific significance during times of financial hardship. By allowing agencies to buy just the computing solutions required, rather than purchasing complicated and
It's a tidal wave that's going to engulf us all within the next five years. Cloud services will be a $160 billion industry by the end of 2011" (Ginovsky 2011, 21). Although the decision to transition from a traditional approach to cloud computing will depend on each organization's unique circumstances, a number of general benefits have been cited for those companies that have made the partial or complete transition to
The user, of course, sees a virtual service (appearing like the data is stored in certain icon), the actual storage could be anywhere, and could vary from day-to-day. This is an advantage to the overall efficiency of the system because storage resources can then be allocated rather than static (Smith, Computing Beyond the Firewall, 2010). Cloud services are any web-based application -- from calendars and contact applications to word processing,
In addition to the stability, scalability and extensibility of its architecture, cloud platform have made it possible for workflows across government to become more pervasive and secure as a result [4]. The TCO of a given cloud platform or series of applications therefore has continued to become reduced by the experience effect (comparable to economies of scale yet only applied to data aggregated and knowledge creation) across government [6].
