Cloud Computing



Cloudcomputing is the use of a network of remote servers that uses theinternet to host, store, process, and manage data instead of apersonal computer or a local server. Also known as on-demandcomputing, cloud computing provides shared data and processingresources to different computers on demand. It provides its user withvarious capabilities data within the third-party centers. Similar toany other utility such as electricity, cloud computing achieveseconomies of scale and consistency by sharing resources over anetwork. This essay studies Pearson’scasestudy on cloud computing “Pearson&nbspManagesDigital Learning in the Cloud with Right Scale” to show how he usedcloud computing, the benefits of cloud computing, and informationsecurity concern that influence his cloud computing solutions.

Pearson’sviews on cloud computing have a great reputation among students andeducators. From his case study, Pearson used cloud computing fordifferent reasons. Firstly, he used cloud computing to test theenvironment for developers in a better way (Pearson,2013).He considered cloud computing to be a fast and more reliablealternative. He used virtual and physical machines to test their codewhereby he would specify versions of operating devices, databases,web servers, as well as any other needed applications. Developerswould send their requests through emails, or they would build a testenvironment. Unfortunately, there was no guarantee that there wouldbe similarities between the production environment and that whichcustomers use. Secondly, Pearson used cloud computing to create asmooth deployment model for customers (Pearson,2013).From the start, Pearson’s aim was to install school and districtswith SuccessMakers in their data centre. However, this was achallenge due to school’s tight budgets and inexperienced IT staff.To deal with this issue, Pearson decided to install every data centerwith SuccessMaker. Correspondingly, this option was very costly sinceit required high capital expenditure and many resources. Hence, thewhole process was nearly impractical. Finally, Pearson used cloudcomputing to fasten on-boarding for his customers. Pearson was somuch determined to ensure his programs were very efficient aspromised. Therefore, he made use of cloud computing to provide everydata centre had the correct software.

Fromthe Pearson’s case study, cloud computing has several benefits.Firstly, cloud computing delivers highly innovative and high-qualitysolutions. According to Mowbray,Pearson, and Shen (2012),cloud computing is efficient, and it offers rapid improvement. Itoffers one central place to make data connections, manageunit-testing, debug, iterate features, as well as investigate code.Further, Mowbrayet. al., (2012) urges that it save time that would otherwise be usedmanage multiple tools. Secondly, cloud computing is relatively quickand cost effective. For instance, Visual Studio delivers high-qualitywork, and more so, in a quick and less complicated ways that enhanceusers to deliver quality outcome. Further, cloud computingcontributes to pedagogical goals. Pearson states that cloud computingare essential for learners and educators because it teaches how tothink through learning. The Pearson’s vice president of productmanagement, Leigh Garcia, states that this technology has enabledstudents and teachers to work interactively in ways that wereinitially impossible. It improves ways that teachers teach, as wellas ways that students learn.

Informationsecurity concern is cloud computing is one of the greatest challengesof this technology for enterprises organizations using it (Pearson,2013).Sadly, in many countries, there are no harmonized policies to protectdata hence, it becomes difficult at technical and legal levels tomake interoperability. Further, due to opaqueness in a cloud model,lack of trust in the cloud ecosystem becomes a challenge. There is noclear information on who is responsible for the data in the cloud.
