Everyone is talking about cloud computing nowadays. It has become a new way to do business. Suppose you are an IT analyst of a company and your boss asks you to investigate into cloud computing and present him the services and capabilities it can offer. He instructs you to specially note the security aspects of cloud computing. Moreover, since Amazon is one of the first companies to offer cloud services to the public and has good customer service and reputation, you are going to specifically look into Amazon’s cloud computing services and use it as an example to explain the concept of cloud computing, the services available, and the security aspects.

You are expected to write a report based upon your investigation and provide a detailed answer to the following questions your boss may ask.
1. What is cloud computing? How does it work?
2. What are the typical applications of cloud computing? Explain them.
3. Describe the cloud computing’s infrastructure security including at the network level, the host level, and the application level.
4. Amazon’s cloud computing services is called Amazon Web Services (AWS). The most central and well-known services are Amazon EC2 and Amazon S3. Explain these two services of AWS.
5. Describe the security features of EC2 and S3 for protecting sensitive data and applications.

You are expected to provide a detailed answer that shows a clear understanding to each question’s subject matter. In addition to the module’s "Reading & Study" materials, a minimum of 3 references is required for this assignment and be sure to include complete reference information. Your submission must contain at least 1,500 words and should follow the current APA formatting style. Please refer to the current edition of the APA publication manual for guideline details.

1. Cloud computing can be regarded as a “computing as a service” capability delivered on a pay-for-use and on-demand basis to organizations over the Internet. Besides metered usage and self-provisioning for resources, the cloud services are also characterized by key features like “multitenancy, scalability, and elasticity” (Kumaraswamy, Latif, & Mather, 2009, p. 7). The required resources are shared by multiple users at each of the following levels: network, host, and application. Because the customers’ degree of access to shared resources mainly depends on the type of delivered service model, the cloud computing environment is also described by the “SPI Framework” phrase. The typical architecture of a cloud computing environment contains clients (e.g. mobile, thin or thick), datacenters, and distributed servers. The datacenter houses the applications where the clients subscribe to. Not last, the needs for more computational power are satisfied by distributed servers which might spawn across more physical locations. From management perspective, the decisional process regarding the selection of the service model and deployment is the responsibility of the Cloud Service Provider.
2. Cloud computing provides to clients both applications and ways for manipulating data. Typical applications of cloud services are database and storage. Due to the major capability of the distributed hardware architecture, the data within the database appears to the users as “located in one place” (Elsenpeter, Velte , & Velte, 2010). Amazon’s SimpleDB contains both repositories and links that make easier the data manipulation operations...
