The widespread use of cloud computing services is expected to increase the power consumption of ICT devices in a cloud computing environment and to damage a quality of service since the distance to a server becomes longer than before. This paper presents the method to reduce the power consumed by ICT devices in a cloud computing environment, which consists of installing WAN accelerators as part of cloud resources actively and increasing the packet transfer rate of communication link temporarily. Next, this paper indicates a possibility of detecting a sign of service quality deterioration by monitoring the power consumption pattern of ICT devices, on condition that smart grids are widely introduced and power sensors are attached to ICT devices. Then, in order to prevent the degradation in performance on live migration of virtual machines over a wide area, this paper proposes to dynamically apply WAN accelerator within the network when a virtual machine is moved to a distant center.
