虚拟化技术是现代计算机应用中的重要技术之一，其改变了传统计算机应用的方式，以互联网作为中间媒介 构建服务器与客户端交互的数据及软件应用模式。近些年，虚拟化技术得到了迅猛的发展，虚拟化产品类型不断更新，桌面虚 拟化方案也形成了以VMware和Citrix 两大主体的云桌面解决方案。为此本文对两种方案进行分析，比较二者之间的差别，从 资源利用和架构特点的角度探索桌面虚拟化方案选型计算方法，提出符合实际应用需求的解决方案，并在具体实践中探讨方 案的可行性。结果表明，本文提出的桌面虚拟化方案选型方案能够很好地实现跨网办公，提升系统的应用效率，保证数据的安 全性。

Virtualization technology is one of the important technology of computer application, which has changed the traditional way of computer application. It has build the application mode of data and software between server and client using Internet as a medium. In recent years, virtualization technology has developed rapidly, and the virtual products updated constantly. The cloud desktop virtualization solutions mainly include VMware and Citrix. This paper analyzes the two kinds of schemes, compares their differences. It explores the calculation and selection of desktop virtualization solutions from the architecture characteristics and resource utilization, puts forward solutions to meet the needs of practical application, and explores the feasibility of the scheme in practice. The results show that the desktop virtualization scheme can effectively implement cross-network office, improve the efficiency of application and ensure the security of data.
