摘要：Prompt growth of the demand for computational power has led to the creation of large-scale data centers. They consume enormous amounts of electrical power resulting in high operational costs and carbon dioxide emissions. Moreover, modern Cloud computing environments have to provide high Quality of Service (QoS) for their customers resulting in the necessity to deal with power-performance trade-off. We propose an efficient resource management policy for virtualized Cloud data centers. Proposed scheme Consider task scheduling algorithm and the maximum and minimum utilization threshold value. If the utilization of CPU for a host falls below the minimum threshold, all VMs have to be migrated from this host and the host has to be switched off in order to eliminate idle power consumption. If utilization goes over maximum threshold value then we migrate VMs from the host according to minimum cpu utilization We present evaluation results showing that dynamic reallocation of VMs brings substantial energy savings, thus justifying further development of the proposed policy
