云数据中心资源调度机制研究

云数据中心包含大量计算机，运作成本很高。有效整合资源、提高资源利用率、节约能源、降低运行成本是云数据中心关注的热点。云数据中心通过虚拟化技术将计算资源、存储资源和网络资源构建成动态的虚拟资源池；使用虚拟资源管理技术实现云计算资源自动部署、动态扩展、按需分配；用户采用按需和即付即用的方式获取资源。因此，数据中心对提高资源利用率的迫切需求，促使人们寻求新的方式以建设下一代数据中心。

Research of cloud data center resource scheduling mechanism

The cloud data center contains a large number of computers, high operating costs. Effective integration of resources, improve resource utilization, energy savings, reduce operating costs is a cloud data center attention. Cloud data centers through virtualization technology computing resources, storage and network resources to build a dynamic virtual resource pool; using virtual resource management technology to automatically deploy cloud computing resources, dynamic expansion, according to need; user-demand and pay-that is the way to get the resources used. Therefore, the urgent need to improve data center resource utilization, prompting people to seek new ways to build next-generation data centers.
