Utility computing is used for academic research. In fifth utility model the recent success of commercial cloud providers, computation and storage is being realized. The computational economies are performs major role to proposed as an efficient means of resource allocation. It has been limited due to lack of performance and high overheads. To achieve a high performance resource allocation, addresses the performance limitations and regeneration theory by defining the strategies to reduce the failure, reallocation rate, increase occupancy and increase the utilization of the system. These strategies include overbooking, advanced reservation, just-in-time bidding and using substitute providers for service delivery. These proposed strategies have been evaluated with respect to grid and cloud environments.
