Cloud computing is an emerging technology which provides effective services to the clients. It permits clients to scale up and down their resources usage depending upon their needs Because of this, under provision and over provision problems may occur. To overcome this migration of service utilization Our Paper focuses on overcoming this problem by distributing the resource to multiple clients through virtualization technology to enhance their returns. By using virtualization, it allocates datacenter resources dynamically based on applications demands and this technology also supports green technology by optimizing the number of servers in use. We present a new approach called “Skewness”, to calculate the unevenness in the Multi-tier resource utilization of a server. By optimizing Skewness, we can join different types of workloads adequately and we can improve the whole consumption of server resources.
