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 (http://aws.amazon.com/solutions/case-studies/ericsson/), about Ericsson cloud computing.
Assess how Ericsson benefitted from Amazon Web Services (AWS) in terms of cost reduction, automated software updates, remote access, and on-demand availability.
Ericcson has over 2 billion subscribers so it does have to provide them with instant and on-demand availability. They also want to provide this service at an inexpensive price and make a profit to themselves in the process therefore AWS seems to provide this. Their subscribers are global; it works in 175 countries and certainly seems to be a successful company in that it has generated revenue of USD 28.2 billion in 2010. The AWS allows the company to companies to avoid upfront infrastructure costs, as well as to get their applications up and running faster, with improved manageability and less maintenance. At the same time, it enables the company to adapt its it to fluctuating and unpredictable business demands. What cloud computing does, in essence, and what it provides Ericsson with is the ability to develop their own business whilst AWS takes care of the it whilst aiming to cut costs (Amazon Web Services? 2013.)
Ericsson uses Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Service (Amazon S3), and RightScale for provisioning and auto-scale functionality
Evaluate the scalability, dependability, manageability, and adaptability of Amazon Elastic Compute Cloud (Amazon EC2), Amazon Simple Storage Services (Amazon S3), and RightScale.
Based on the reputation and success that Ericsson has achieved in their providing instant quality service, and based on their satisfaction with the services of AWS, it seems as though AWS indicates more than sufficient scalability for the service, is certainly dependable, and adaptable since it manages to adapt to different countries and fluctuating situations and it shows super manageability. In fact:
The company chose Amazon Web Services (AWS) because they felt AWS was the most integrated public cloud provider in the Rightscale Cloud Management Platform (Rightscale). The Ericsson team states that having hosting centers in various regions was important for them. AWS also showed a better quality of service with solid management and a proven track record.
Examine the security concerns for cloud-based services and make suggestions to cope with these concerns.
The four principles of information security are:
1. confidentiality -- information must be protected from unauthorized contact
1. accessibility -- information must be accessible when needed
1. Integrity -- data must be reliable
1. accountability -- changes in system must be traceable to the one who caused the change (ITRB, 2003)
Some companies may be lax in security concerns, or, even worse, be untrustworthy. The more important the data is to the company, the more careful they should be in selecting a vendor, but at the end of the day protection depends most upon oneself whilst Ericsson or anyone else employing these companies constantly monitor their tasks to ascertain that they are doing a reputable job. Also important is the fact that he constantly backup his data to ensure its safety. (DOD, 2001).
In order to protect for security concerns, some companies use SQL 2008, and transparent database encryption. They also use DDL triggers as well as ascertaining that they and employees know constantly who is having access to their data. Great care is taken with passwords and with all methods of keeping data secure and safe.
Assess possible scalability, reliability, and cost issues associated with cloud computing, and make suggestions to overcome each of these issues.
