Case Study: Cloud Computing |
Cloud computing is becoming a popular and efficient service for many companies. With the speed that technology is changing, it can be difficult for a company to stay ahead with the current systems and services available in the market. Cloud computing is one option companies have to address this issue. “With cloud computing, organizations can consume shared computing and storage resources rather than building, operating and improving infrastructure on their own,” (Varia and Mathew, 2012). Ericsson is a world leader in providing technology and services for telecommunication and they also utilize Amazon Web Services, a public cloud services ...view middle of the document...
This web access capability also provides on-demand availability. AWS can be accessed at any time and from any place.
Amazon Elastic Compute Cloud or EC2 is a web service that provides computing services in the cloud. It is highly adaptable in allowing a user to select an arrangement of memory, CPU, and storage that is needed and also with the operating system of the user’s choice, (Amazon Elastic Compute Cloud). It also provides the user with the choice to scale capacity up or down depending on what computing requirements the user needs, “Amazon EC2 enables you to increase or decrease capacity in minutes,” (Amazon EC2). EC2 also offers significant manageability in giving complete control to the user by “giving root access to each server instance” and the ability to interact with them as you would with any other machine, (Amazon EC2). EC2 also carries proven reliability in using Amazon’s data centers and network infrastructure, “The Amazon EC2 service level agreement commitment is 99.95% availability for each of EC2’s regions,” (Amazon EC2).
Amazon Simple Storage Services or S3 offer storage space on the Internet. Amazon ensures it dependability with “systematic, regular data integrity checks and is built to be self-healing” (Amazon Simple Storage Services). Other storage systems use manual repair and labor-intensive verification techniques to ensure data quality. Another benefit of cloud storage is S3’s scalability and manageability. A user only pays for the services that are being used which can be scaled up or down depending on the needs of the business, “Amazon S3 provides a number of capabilities to simplify the lifecycle management of your data, including management of capacity, automated archival to lower cost storage, and scheduled deletions,” (Amazon S3).
RightScale is a management platform that is used in conjunction with several cloud services including Amazon Web Services. It provides a platform to manage and control business applications in the cloud or across multiple cloud services. RightScale offers cloud manageability for even inexperienced cloud users with their server templates that were designed for dependability with “best-practice” design architectures and common application scenarios in mind (RightScale). RightScale uses an open architecture to allow complete visibility into all levels of a user’s cloud deployment and also offers automation across the deployment of cloud services, (RightScale).
There are many concerns regarding security when considering a cloud-based solution. Vic Winkler describes several in his article for TechNet magazine such as the loss of control. A major concern for businesses that use cloud services is the loss of control of the data that is being uploaded into the cloud. By using a third party to manage, compute, store data, a business puts the responsibility for that data into the provider’s hands. If a company is storing proprietary information on a cloud server,...
