虚拟化技术比较研究

Comparative Study on Virtualization Technology

近年来,虚拟化技术和产品已趋成熟,企业中也开始推动虚拟化技术的应用,如:服务器整合、强化商业连续性、用于测试及部署以及动态数据中心等。阐述了虚拟化技术的重要性,分析比较了业界常用的虚拟化技术包括全虚拟化、半虚拟化、硬件仿真和操作系统虚拟化;从可靠性、易用性、成本、扩展性和实施的难易程度几个方面评价了主流的虚拟化解决方案,包括VMware、Microsoft、Redhat、Citrix,最后给出了企业实施虚拟化的建议。

In recent years, virtualization technology and products have become mature,companies also began to promote the application of virtualization technology, such as： server consolidation, enhanced business continuity, for testing and deployment and dynamic data centers, etc. This paper expounds the importance of the virtual technology, analyzes and compares the virtualization technology used in the industry, which includes full virtualization, para-virtualization, hardware simulation and the operating system virtualization; in several aspects （Reliability, ease of use, cost, scalability and ease of implementation）, the paper has evaluated the mainstream of virtualization solutions （Microsoft, Redhat, VMware, Citrix）. Finally, some suggestions are proposed to implement virtualization.
