With rapid development and gradual maturity of cloud computing technology, cloud computing service on the Internet is also widely applied. However, the issue of high energy efficiency becomes a main issue facing the opening of cloud computing new era. With social development in recent years, virtualization technology and could computing mode also get rapid development due to such features as flexible management, high resource utilization rate and good expandability. Moreover, they can be used to predict wide prospects in future data centers. For a solution to high energy consumption of cloud computing data center, we combine traditional energy consumption management techniques with virtualization technologies, and propose an effective model and measuring method under cloud computing environment. This is an important research orientation.
