Optimal allocation approach of virtual servers in cloud computing

In this paper an optimal allocation approach of virtual servers to appropriate data centers is proposed for a network made up of collections of data centers and user groups. The virtual server allocation can be formalized as a linear programming (LP) problem which consists in minimizing the round-trip-times (latencies) between data centers and user groups. Our proposed allocation approach demonstrated good capabilities when evaluated under round-trip-time and group requirements (workload) changes.
