A data center is equipped with a large quantity of servers, storage devices, and networking facilities. Aided by virtualization technology, the population of a data center can be decreased, thus enabling a very significant reduction in power consumption, enhancing a corporation’s competitive advantage, while concurrently lowering operational costs. Hence, built upon the virtualization technology and resource distribution principle, this paper will apply the pre-defined scenario model on the virtual environment to propose the SPS scheme for reducing power consumption in cloud servers. Also, this paper integrates the Linux platform to design the management module for SPS, called SPSM. Subsequently, the SPS can automatically optimize the power distribution based on the pre-defined scenario model via SPSM. When the monitor program discovers an increase in the VM’s workload, the wake-up function of the SPS can activate the server and then perform live migration among VMs by utilizing the automatic workload balancing in the virtual environment. By analyzing the experimental results, the applications of the SPS scheme can obtain higher CPU and memory utilizations of servers to achieve a 21% reduction in power consumption. Finally, the purposes of the proposed SPS are to attain better processing performance and obtain higher resource utilizations of VMs in cloud computing.
