Cloud Computing In the Government
As a second part to this report, is a case study written by Tom Kwasniewski, Software Engineer at Quanterion Solutions, Inc. that is a detailed account of migrating an existing application to the Microsoft Azure cloud environment. The actual implementation of the migration and the issues found are discussed.
Cloud Migration: A Case Study of Migrating an Enterprise IT System to IaaS
Khajeh-Hosseini, A.; Greenwood, D.; Sommerville, I.; This case study illustrates the potential benefits and risks associated with the migration of an IT system in the oil & gas industry from an in-house data center to Amazon EC2 from a broad variety of stakeholder perspectives across the enterprise, thus transcending the typical, yet narrow, financial and technical analysis offered by providers. Our results show that the system infrastructure in the case study would have cost 37% less over 5 years on EC2, and using cloud computing could have potentially eliminated 21% of the support calls for this system. These findings seem significant enough to call for a migration of the system to the cloud but our stakeholder impact analysis revealed that there are significant risks associated with this. Whilst the benefits of using the cloud are attractive, we argue that it is important that enterprise decision-makers consider the overall organizational implications of the changes brought about with cloud computing to avoid implementing local optimizations at the cost of organization-wide performance.
Open Source Cloud Computing Tools: A Case Study with a Weather Application
Case Study by Manuel Rodriguez-Martinez, Jaime Seguel and Melvin Greer. Cloud Computing is a promising paradigm designed to harness the power of networks of computers and communications in a more cost effective way. Clouds provide elastic capacity to serve a wide and constantly expanding range of information processing needs, including government, military, business and education. The Cloud Computing paradigm is maturing rapidly and is being considered for adoption in government and business platforms. Open source systems refer to software systems whose source code is available, allowing for immediate incorporation of improvements and adaptations of the system by its users. This paper reports on an evaluation of open source development tools for Cloud Computing. The main tools examined are Eucalyptus, Apache Hadoop, and the Django-Python stack. These tools were used at different layers in the construction of a notional application for managing weather data. The results of our experience are reported in terms of a capability matrix that grades nine different aspects associated with the use of these tools in the development and deployment of applications in open source Cloud Computing environments.
