Abstract:

As a new distributed computing technology,cloud computing becomes more and more popular.Cloud computing is rapidly changing the computing environment for various applications.However,as global energy price increases,the power consumption problem of cloud data centers becomes more and more serious.Since one major goal of cloud computing is to provide cheap but efficient services,the huge energy costs of these cloud services must be taken under consideration.How to improve energy efficiency becomes increasingly important throughout the cloud platform.The composition of energy consumption in cloud data center was analyzed,it thoroughly classifieds,analyzed and summarized the related work of energy consumption management.Finally,the paper summarized the research and pointed out future research directions.

Key words: cloud computing, data center, power consumption, virtualization
