Cloud computing is a new trend for computing resource allocation. Successful development of cloud computing paradigm necessitates accurate performance evaluation of cloud data centers. The computing resource allocation and performance managing have been one of the most important aspects of cloud computing. In this paper, the resource allocation is modeled as queues and the virtual machines are modeled as service centers. The authors considered, M/G/s queue as a tool regulate task's arrivals and general service time for requests with single server and infinite waiting space.
