Policy Based Resource Allocation in Cloud Systems

Cloud Systems provide computing resources in a flexible manner. There are several key requirements that need to be addressed regarding the resource allocation in Clouds and the most important of them is providing on demand elasticity. This paper focuses on adding new features to the Cloud resource allocation mechanism that enhance on demand elasticity. Most of the resource managers that are now on the market use static allocation. We propose a novel solution that uses dynamic allocation, based on well defined policies. Moreover, the proposed solution offers authentication and accountability for the actions of the users which is very important for the commercial aspect of public clouds.
