Nowadays public clouds offer a scalability that is often beyond what a user would be able to afford otherwise. Cloud bursting allows businesses leverage the cloud without losing the comfort and control of in-house data centre operations. Looking at cost, security and resource utilization angles we need a dynamic infrastructure to decide about the hybrid mix ie, private and public clouds. In this paper, we propose a general paradigm where software stacks need to be rearchitected to dynamically be able to run either in public or private clouds. The queries get executed in private or public clouds based on cost, security and resource utilization models chosen by the clients. Copyright 2012 ACM.
