Emergence of cloud computing has facilitated the provisioning of computing resources in an on-demand basis that can be swiftly allocated, released and reallocated with minimum management effort and cost. One important element of cloud is the virtual machine which encapsulates business services and acts as a resource carrier. An important task of cloud computing is to find an optimal placement scheme that can map the virtual machines to physical machines. With the increasing prevalence of large scale cloud computing environments, how to efficiently place VMs into available computing servers has become an essential research problem. This research works presents a Virtual Machine Placement and Load Rebalancing Based on Multi-Dimensional Resource Characteristics in Cloud Computing Systems (VMP-LR) to improve the efficiency of VM placement
