%X In Virtualized Data Center (VDC), a single Physical Machine (PM) is logically divided into one or moreVirtual Machines (VMs) that share physical resources. Therefore, dynamically resource provisioning playsan important role in VDC. Moreover the resource provider would like to maximize resource utilization,which forms a large portion of their operational costs. To achieve this goal, several consolidations can beused to minimize the number of PMs required for hosting a set of VMs. However, consolidation is oftenundesirable for users, who are seeking maximum performance and reliability from their applications.These applications may indirectly increase costs due to under-provisioning of physical resources.Moreover frequent Service Level Agreement (SLA) violations result in lost business. To meet SLArequirements, over provisioning of resources is used. However, if the services do not use all the CPU theyhave beenallocated;the provider will suffer from low resource utilization, since unused resources cannotbe allocated to other services running in the provider. Therefore VM provisioning is the most vital step indynamic resource provisioning. In this paper, correlation based VMs provisioning approach is proposed.Compared to individual-VM based provisioning, correlation based joint-VM provisioning could lead tomuch higher resource utilization. According to the experimental results, proposed approach can savenearly 50% CPUresource in terms of overall CPU utilization
