【摘要】：目前在企业或政府部门机构中,传统的桌面办公系统存在着一些不足：配置部署复杂,维护更新代价大、数据安全保障机制不完善等。随着虚拟化技术的日益成熟及其广泛的应用前景,虚拟化已成为当今的研究热点。虚拟化一般可分为服务器虚拟化、网络虚拟化、存储虚拟化及桌面虚拟化。其中前面三种虚拟化特别是服务器虚拟化已经被IT界广泛使用,但是随着虚拟化技术向桌面计算的延伸,桌面虚拟化技术也越来越受到人们的关注。桌面虚拟化与传统桌面环境相比,最主要的优势是可以集中化管理和交付,有效降低IT成本,提升信息安全：同时用户在任何地方都可拥有相同且个性化的计算环境,有效提高移动性。本文首先细致地分析了桌面办公的一般性功能需求,并对目前桌面虚拟化解决方案进行了分析和比较,然后在针对某公司桌面办公具体需求分析调研的基础上,设计并实现了一套面向公司办公的桌面虚拟机管理系统。所实现的桌面虚拟化管理系统除了具备虚拟化技术所带来的桌面管理优势外,还具备如下三个特色功能：首先,把该系统与该公司的人事管理系统相结合,实现了从员工入职到离职全过程的桌面虚拟机生命周期管理；其次,在该系统中实现了智能化的能耗管理优化功能,在保证员工桌面办公便捷的前提下,降低后台服务器系统的总体能耗；最后,在系统中进行了面向提高性能的虚拟化资源共享优化改进,提高了服务器支持更多桌面虚拟机的能力,优化了虚拟机的操作响应速度。本文还对桌面虚拟化系统的软硬件配置和网络拓扑结构等共性问题进行了分析和讨论,对项目具体实施中的典型问题和解决方法进行了简要的阐述。这些最佳实践可为其他中小型企业部署桌面虚拟化系统提供有价值的技术参考。
[Abstract]:At present, there are some shortcomings in traditional desktop office system in enterprises or government departments, such as complicated configuration and deployment, high cost of maintenance and update, imperfect data security mechanism, and so on. With the increasing maturity of virtualization technology and its wide application prospects, virtualization has become a research hotspot. Virtualization can generally be divided into server virtualization, network virtualization, storage virtualization and desktop virtualization. The first three kinds of virtualization, especially server virtualization, have been widely used in the field of IT, but with the extension of virtualization technology to desktop computing, desktop virtualization technology has been paid more and more attention. Compared with traditional desktop environment, desktop virtualization has the advantage of centralizing management and delivery, reducing IT cost and improving information security. At the same time, users can have the same and personalized computing environment anywhere. Improve mobility effectively. In this paper, the general functional requirements of desktop office are analyzed in detail, and the current desktop virtualization solutions are analyzed and compared. A desktop virtual machine management system for company office is designed and implemented. In addition to the advantages of desktop management brought by virtualization technology, the realized desktop virtualization management system also has the following three features: first, combine the system with the personnel management system of the company. It realizes the life cycle management of the desktop virtual machine from the beginning to the leaving of the staff. Secondly, the intelligent optimization function of energy consumption management is realized in the system, which ensures the convenience of the desktop office of the staff. Finally, we improve the performance oriented virtualization resource sharing optimization in order to improve the server's ability to support more desktop virtual machines and optimize the response speed of virtual machines. This paper also analyzes and discusses the common problems such as hardware and software configuration and network topology of desktop virtualization system, and briefly describes the typical problems and solutions in the implementation of the project. These best practices provide a valuable technical reference for other small and medium-sized enterprises to deploy desktop virtualization systems.
