【摘要】：目前在企業(yè)或政府部門機(jī)構(gòu)中,傳統(tǒng)的桌面辦公系統(tǒng)存在著一些不足：配置部署復(fù)雜,維護(hù)更新代價(jià)大、數(shù)據(jù)安全保障機(jī)制不完善等。 隨著虛擬化技術(shù)的日益成熟及其廣泛的應(yīng)用前景,虛擬化已成為當(dāng)今的研究熱點(diǎn)。虛擬化一般可分為服務(wù)器虛擬化、網(wǎng)絡(luò)虛擬化、存儲(chǔ)虛擬化及桌面虛擬化。其中前面三種虛擬化特別是服務(wù)器虛擬化已經(jīng)被IT界廣泛使用,但是隨著虛擬化技術(shù)向桌面計(jì)算的延伸,桌面虛擬化技術(shù)也越來(lái)越受到人們的關(guān)注。桌面虛擬化與傳統(tǒng)桌面環(huán)境相比,最主要的優(yōu)勢(shì)是可以集中化管理和交付,有效降低IT成本,提升信息安全：同時(shí)用戶在任何地方都可擁有相同且個(gè)性化的計(jì)算環(huán)境,有效提高移動(dòng)性。 本文首先細(xì)致地分析了桌面辦公的一般性功能需求,并對(duì)目前桌面虛擬化解決方案進(jìn)行了分析和比較,然后在針對(duì)某公司桌面辦公具體需求分析調(diào)研的基礎(chǔ)上,設(shè)計(jì)并實(shí)現(xiàn)了一套面向公司辦公的桌面虛擬機(jī)管理系統(tǒng)。所實(shí)現(xiàn)的桌面虛擬化管理系統(tǒng)除了具備虛擬化技術(shù)所帶來(lái)的桌面管理優(yōu)勢(shì)外,還具備如下三個(gè)特色功能：首先,把該系統(tǒng)與該公司的人事管理系統(tǒng)相結(jié)合,實(shí)現(xiàn)了從員工入職到離職全過(guò)程的桌面虛擬機(jī)生命周期管理；其次,在該系統(tǒng)中實(shí)現(xiàn)了智能化的能耗管理優(yōu)化功能,在保證員工桌面辦公便捷的前提下,降低后臺(tái)服務(wù)器系統(tǒng)的總體能耗；最后,在系統(tǒng)中進(jìn)行了面向提高性能的虛擬化資源共享優(yōu)化改進(jìn),提高了服務(wù)器支持更多桌面虛擬機(jī)的能力,優(yōu)化了虛擬機(jī)的操作響應(yīng)速度。 本文還對(duì)桌面虛擬化系統(tǒng)的軟硬件配置和網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)等共性問(wèn)題進(jìn)行了分析和討論,對(duì)項(xiàng)目具體實(shí)施中的典型問(wèn)題和解決方法進(jìn)行了簡(jiǎn)要的闡述。這些最佳實(shí)踐可為其他中小型企業(yè)部署桌面虛擬化系統(tǒng)提供有價(jià)值的技術(shù)參考。
[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.
