Leveraging the Cloud for Green IT – Voted Best Paper at CMG International ’09
Cloud computing is maturing, becoming a viable alternative to classic on-premise IT. Cloud facilitates scalability, promising lower fixed and variable costs while supporting enterprise growth. The scalability benefits and cost savings can be achieved through on-demand infrastructure provisioning and reduced on-premise energy consumption. The benefits are compelling; however, a quantitative analysis is required. This paper describes and demonstrates a methodology for predicting performance, energy and cost for expanding on-premise IT into the Cloud.
