虚拟化工程应用及效益分析

Virtualization Engineering Application and Benefit Analysis

节约成本和提高效能是许多企业IT部门面临的难题。随着虚拟化技术的流行，很多企业开始考虑是否将其应用到本企业的数据中心，以获得理想的经济效益。那么服务器虚拟化方案是否适合所有的企业，是否一定会带来成本节约呢？答案并没有那么简单。本文通过一个虚拟化工程案例阐述了虚拟化的全过程，并对结果进行了效益分析。从这个工程案例得出以下结论：并非所有的服务器都适合虚拟化。只有通过虚拟化评估符合一定条件的服务器，才适合采用虚拟化技术；并非所有的企业都会从虚拟化技术中获益。只有企业数据中心的可虚拟化服务器达到一定数量后，虚拟化方案才会有比较可观的效益。另外，本文还详细介绍了虚拟化的其他方面优势如：高可用，在线迁移，简化管理等等。

The cost savings and improve the effectiveness of corporate IT departments face many challenges.With the popularity of virtualization technologies,many companies began to consider whether to apply it to the corporate data center to obtain the desired economic benefits.Server virtualization solution that suitable for all businesses,whether it will bring about cost savings.The answer is not so simple.This paper describes a virtual engineering case the whole process of virtualization,and the results are benefit analysis.Case from this project following conclusions：Not all servers are suitable for virtualization.Only through the virtual server that meet certain conditions assessed,only suitable for virtualization technology;not all companies will benefit from virtualization.Only enterprise data centers can achieve a certain number of virtualized servers,the virtualization program will have more substantial benefits.In addition,the article also details the advantages of other aspects of virtualization such as：availability,online migration,simplified management.
