虚拟化技术在开放大学云计算数据中心的应用研究

Application of Virtualization Technology to Cloud Computing Data Center in Open University

开放大学数据中心建设过程中存在着资源利用率低、管理成本较高等问题,尝试利用云计算服务模式和虚拟化技术,提供一种解决思路。在分析虚拟化、云计算、数据中心等关键技术的基础上,提出了云计算数据中心可用性参考模型CCDCAM,并描述了模型中多层服务可用性之间的映射关系,同时分析了数据中心建设过程中虚拟化平台可用性、安全性和双活数据中心中相关虚拟化技术。最后通过模拟实验验证了虚拟化技术可以提高开放大学云计算数据中心的资源利用率和业务系统的可用性。

There are the problems of low rate of resource utilization and high management cost in the construction of data center in Open University. This paper tries to take advantage of cloud computing service mode and virtualization technologies to provide a solution to the problems. Based on the analysis of the key technologies such as virtualization,cloud computing,data center,cloud computing data center availability reference model（CCDCAM） is put forward,and the mapping relations between the multilayer service availability in the model are described; at the same time,the availability and security of virtualization platform in the process of the data center construction,and the relevant virtualization technology in double live data center are analyzed. Finally,simulation experiment verifies that virtualization technology can improve the resource utilization of cloud computing data center in Open University and the availability of business system.
