Stretching Site Resources in Cloud Computing

A stretchy site mechanism is to solve the allocation of resources problem of computation capacity in the environment of cloud computing is proposed here. In this paper, the authors investigate the benefits that organizations can reap by using "Cloud Computing" providers to augment the computing capacity of their local infrastructure. They have implemented a resource manager, built on the Nimbus toolkit to dynamically and securely extend existing physical clusters into the cloud. Requests for resources are submitted to the organisation's cluster, but additional Resources s are instantiated in the remote provider and added to the local cluster when there are insufficient resources to serve the users' requests.
