ABSTRACT
Cloud computing is defined by Cearly and Phifer in their case study titled “Case Studies in Cloud Computing” as “a style of computing in which scalable and elastic IT-related capabilities are provided ‘ as a service’ to customers using Internet technologies”. Cloud computing services had been provided by major vendors such as Google, Amazon, Microsoft, IBM, Hewlett-Packard, and others for business computing until recently when Apple Corporation announced iCloud for consumers. Therefore, cloud computing is now available for businesses as well as consumers. Read the case study titled, “ Ericsson”, located here, about Ericsson cloud computing.   Case Study 2: Cloud Computing

Cloud computing has made company information systems more flexible and accessible. It uses the internet to offer computing resources, such as software, as a service. There are many benefits associated with switching over to cloud computing. One example is cost reduction, which is due to the need of fewer licenses for the software a company uses. Ericsson uses cloud computing for their operations. This paper will review the success of Ericsson’s use of cloud computing. Furthermore, problems and issues associated with cloud computing will be assessed, such as security, scalability, reliability, and cost. Assess how Ericsson benefitted from Amazon Web Services (AWS) in terms of cost reduction, automated software updates, remote access, and on-demand availability. The use of cloud computing has become common practice in today’s workplace. Ericsson turned to Amazon Web Services (AWS) to reduce costs, the availability of automated software updates, remote acess, and on-demand availability. Cost reduction was achieved with the use of AWS cloud computing since the company only has to worry with a low fee. There is no need to purchase extra licenses or hardware. Through AWS, Ericsson can save on the cost of purchasing servers and other hardware by employing virtual servers available through the cloud computing service provider. Ericsson can save time and money knowing that AWS is setup to provide automated software updates to the system as they become available. No more time and money will be spent on manually updating each machine with software updates. AWS is no different from any other cloud computing service in regards to remote access and on-demand availability. Ericsson employees and authorized personnel can access AWS from any internet access point and at any time needed.

Evaluate the scalability, dependability, manageability, and adaptability of Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Services (Amazon S3), and RightScale.
There are several applications within Amazon Elastic Compute Cloud (Amazon EC2) that address the issues of scalability, dependability, manageability, and adaptability. “Amazon's CloudWatch Web service gives users greater visibility into how they're using the resources, how those resources are working and patterns in demand, from network traffic to CPU utilization. Users can select the EC2 instance that they want to monitor, and CloudWatch will begin collecting and storing data that customers can access using Web service APIs or CLTs (Command Line Tools)” (Burt, 2009). Furthermore, “Customers also can use Amazon's Auto Scaling feature to ramp EC2 capacity up or down, depending on need. The capability lets businesses have the necessary resources when demand spikes, then pare back when it eases” (Burt, 2009). EC2 demonstrates that is scalable, dependable, manageable, and adaptable with these available functions. Amazon Simple Storage Services (S3), “is a scalable, high-speed, low-cost Web-based service designed for online backup and archiving of data and application programs” (Rouse, 2010). “Amazon S3 can scale in terms of storage, request rate, and users to support an unlimited number of web-scale applications” (Amazon Web Services, 2012). Reliability of S3 is stated...
