Richer Requirements for Better Clouds

Abstract

Resource usage in Clouds can be improved by deploying applications with richer defined requirements. Such "richer requirements" involve wider application / user specific context capture expressed in interrelated models. The use of model based requirements is presented using input from test-beds monitoring resource use in terms of Trust, Risk, Eco-Efficiency and Cost (TREC) models. The results of this application illustrate the potential that richer requirements have for better management of resources in Clouds.
