We present the design of a dynamic provisioning system that is able to manage the resources of a federated cloud environment by focusing on their utilization. With our framework, it is not only possible to allocate resources at a particular time to a specific Infrastructure as a Service framework, but also to utilize them as part of a typical HPC environment controlled by batch queuing systems. Through this interplay between virtualized and non-virtualized resources, we provide a flexible resource management framework that can be adapted based on users' demands. The need for such a framework is motivated by real user data gathered during our operation of FutureGrid (FG). We observed that the usage of the different infrastructures vary over time changing from being over-utilized to underutilize and vice versa. Therefore, the proposed framework will be beneficial for users of environments such a FutureGrid where several infrastructures are supported with limited physical resources.
