云计算作为一种新的分布计算技术,变得越来越流行,很多院校和企业都建立了云计算数据中心.在一个数据中心中,电力的消耗越来越严重,随着全球能源的涨价,数据中心的能耗的成本也在增加.云计算的一个主要目标是通过规模经济为用户提供省钱的服务,而这些云服务的能耗成本已经非常显著了.因此,如何提高整个云平台的能耗效率变得越来越重要.很明显,如何测量实际的能耗对于能量管理策略至关重要.提出一个能耗测量和管理的框架,并建立一个简单的评估能量消耗的模型,在此基础上研究基于能耗的动态资源分配机制和资源管理方法.%As a new distributed computing technology, cloud computing becomes more and more popular. Many institutions and companies have established their own cloud computing data centers. However, as global energy price increases, the power consumption problem of 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 authors propose a framework for measuring and managing energy consumption, and then establish a prototype model for assessment and management of energy consumption. Finally, some researches are done about dynamic resource allocation and resource management mechanism based on energy consumption.
