...Cloud Computing – Case Study CIS500 Introduction Cloud computing is tech jargon which describes an Internet service that allows company employees to communicate via emails, access massive amounts of data instantaneously at various times and places without the network becoming clogged down due to heavy load usage. Ericsson describes itself as, “a world leader in the rapidly-changing environment of communications technology – providing equipment, software and services to mobile and fixed network operators all over the globe” (Ericsson n.d.). Amazon initiated their web service (AWS) in 2006, by offering IT infrastructure services to businesses in the form of web services referred to as cloud computing. One of the key benefits of cloud computing is the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business (Amazon 2014). Ericsson benefits of AWS Amazon Web Services provided Ericsson with a highly integrated public cloud with hosting centers in practically every region in the country. This benefit would be a big plus due to the universal impact that Ericsson makes in the telecommunication industry where they provide services to more than one billion consumers. Cost savings was a significant benefit for Ericsson due to not having to expend the capital to build a comparable IT infrastructure internally. Arpit Joshipura, Ericsson Vice President of Silicon Valley (2014) states that, “With cloud computing...

...Security Considerations for Cloud Computing Carlos Chandler Abstract Cloud computing is an emerging Information Technology (IT) model whereby a company utilizes a pay-per-use service for it computing needs rather than maintain a local data center run by its in-house IT department. By treating computing resources as a commodity or operating expense, it allows firms to focus less on IT and more on the core elements of the operations strategy. Because of advantages like this, its popularity has grown exponentially in recent years. However, cloud computing also has certain inherent risks in its present form. This paper seeks to understand the key advantages driving businesses to adopt this computing model in ever increasing numbers, while at the same time understanding what risks they are taking in doing so. To gain insight into these risks, this paper incorporates statistical research into what experts in the field believe to be the greatest down-sides to converting to this increasingly common IT model. Security Considerations for Cloud Computing What is Cloud Computing, Anyway? To begin, let us illustrate what cloud computing is. Imagine you run a cookie baking business that takes orders from around the country via an online store. To handle the orders, would your business buy a fleet of trucks and deliver its own shipments, or would you simply contract with UPS or FedEx to ship the orders on your behalf? Clearly the cost efficiencies in contracting the shipping...

On the one hand, cloud computing saves money because it does not require IT infrastructure, servers, and it is very scalable. On the other hand, it might lead to financial loss due to security risks, possible data access problems, data privacy policies, etc. Therefore, cloud computing evaluation based on financial metrics is proposed in this article. This paper consists of four major sections. The first section is a literature review of cloud computing and its types. The next section describes some common financial metrics such as CBA, ROI and TCO and describes how they might be applied to evaluate cloud computing. The third section proposes evaluation strategies, and the last section contains the evaluation of a series of cloud computing projects based on chosen evaluation strategies, and results are verified based on expert opinion. Keywords – cloud computing, CBA, ROI, TCO, ROC computing as “a model for enabling convenient, on-demand network access to a shared pool of configuration computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction”...

After the review of each case study, a set of questions will be answered to provide details on each study as to what was reviewed. Challenges and Security Issues (Case Studies) Introduction In this assignment, review of three different case studies will be discussed. Topics will include when an antivirus software cripples your computer, determining how secure cloud computing is, and electronic medical records systems. Case Study #1 When Antivirus Software Cripples Your Computers On April 21, 2010, McAfee crippled hundreds of thousands of McAfee equipped machines, by mistakenly sending an update to its users reclassifying svchost.exe as being a malicious file which was known as W32/wecorl.a virus (Humphries, 2010, para 1-2). The factors that were responsible for this software problem was that McAfee failed to send users a warning notifying them that svchost.exe was going to be either deleted or quarantined; instead they deleted the file completely. On the other hand, failure to detect this error was at the fault of McAfee’s automated quality assurance. Another reason this spread so quickly is because of the high demand for faster antivirus updates....
