Synchronization of Data and Resources in Distributed, Cooperative Virtual Data Centers

The cooperation is to reduce both capital and operational expenditures in running a data center while providing a greener solution. In the aspect of performance in such a distributed solution, performance can be improved by replicating the server and subsequently dividing the work. But, the main concern is keeping all replicas up-to-date, and we have observed a variety of synchronous and consistency models. This paper investigates a few synchronous schemes for a cooperative virtual data center between multiple entities which is founded on the principal of fair resource sharing among the entities.
