A Policy-Based Framework for Managing Data Centers

A data center is defined as a set of computing resources that is owned by an organization and shared among multiple applications from different client organizations. Applications often have non-functional run time requirements for different classes of users. These are referred to as service level objectives (SLO) and are considered part of a service level agreement (SLA). Allocating resources to an application should be dynamic and based on specific run-time conditions. It should be possible to change these conditions without recoding. This paper describes a framework, a prototype based on this framework and an application of the prototype that dynamically allocates resources and allows the application environment to adapt in the case of having insufficient resources
