【摘要】：云計(jì)算是目前計(jì)算機(jī)最為火熱的研究領(lǐng)域之一，桌面云作為云計(jì)算中的一種，具有易于部署、安全性高和數(shù)據(jù)集中管理的特點(diǎn)。桌面云能將傳統(tǒng)的桌面環(huán)境轉(zhuǎn)移到數(shù)據(jù)中心，使其與終端設(shè)備解耦，用戶能夠使用瘦客戶端等終端設(shè)備隨時(shí)隨地通過(guò)網(wǎng)絡(luò)接入屬于個(gè)人的桌面環(huán)境，提高辦公的靈活性和資源的使用率。此外，桌面云解決了傳統(tǒng)PC資源與服務(wù)器資源使用率低、運(yùn)維成本高、安全系數(shù)低等問(wèn)題，同時(shí)能夠彌補(bǔ)瘦客戶端等終端設(shè)備的計(jì)算和存儲(chǔ)能力的不足，充分發(fā)揮移動(dòng)辦公的優(yōu)勢(shì)。 本文首先對(duì)桌面云的研究現(xiàn)狀進(jìn)行介紹，并闡述了系統(tǒng)所涉及到的核心概念和技術(shù)，然后對(duì)現(xiàn)階段桌面虛擬化的主流技術(shù)架構(gòu)進(jìn)行了對(duì)比分析。在完成以上技術(shù)理論研究的基礎(chǔ)上，提出了混合型桌面云服務(wù)端架構(gòu)并對(duì)架構(gòu)的核心特點(diǎn)進(jìn)行分析，然后對(duì)該架構(gòu)的構(gòu)建方式進(jìn)行總體設(shè)計(jì)，包括整體架構(gòu)設(shè)計(jì)、邏輯架構(gòu)設(shè)計(jì)、功能結(jié)構(gòu)與模塊設(shè)計(jì)，以及系統(tǒng)核心類圖的設(shè)計(jì)等方面，這部分內(nèi)容是整個(gè)系統(tǒng)構(gòu)建的基礎(chǔ)。然后針對(duì)架構(gòu)設(shè)計(jì)中引申出的問(wèn)題進(jìn)行分析和給出相應(yīng)的解決方案，并說(shuō)明所采用的解決方案的設(shè)計(jì)優(yōu)點(diǎn)。 在完成混合型桌面云服務(wù)端架構(gòu)的設(shè)計(jì)后，本文第四章進(jìn)一步對(duì)整個(gè)系統(tǒng)進(jìn)行實(shí)現(xiàn)。從功能模塊的角度對(duì)系統(tǒng)進(jìn)行詳細(xì)設(shè)計(jì)與實(shí)現(xiàn)，，首先實(shí)現(xiàn)構(gòu)建數(shù)據(jù)中心過(guò)程中所涉及的相關(guān)功能，包括節(jié)點(diǎn)的動(dòng)態(tài)加入和退出、數(shù)據(jù)中心容量的計(jì)算，以及物理資源的池化等功能的設(shè)計(jì)與實(shí)現(xiàn)。然后詳細(xì)設(shè)計(jì)并實(shí)現(xiàn)了虛擬機(jī)管理和虛擬資源管理兩大功能模塊的各個(gè)子模塊。此外，還完成了系統(tǒng)的監(jiān)控模塊以及系統(tǒng)的服務(wù)接口等部分的設(shè)計(jì)與實(shí)現(xiàn)。接下來(lái)，對(duì)系統(tǒng)的運(yùn)行效果和性能進(jìn)行了測(cè)試，并對(duì)測(cè)試結(jié)果進(jìn)行了分析研究。在本文的最后部分對(duì)全文進(jìn)行總結(jié)和展望。
[Abstract]:Cloud computing is one of the hottest research fields of computer. Desktop cloud as one of cloud computing has the characteristics of easy deployment, high security and data centralized management. The desktop cloud can transfer the traditional desktop environment to the data center and decouple it from the terminal device. The user can use the thin client and other terminal devices to access the personal desktop environment anytime and anywhere through the network. Improve office flexibility and resource utilization. In addition, the desktop cloud solves the problems of low utilization rate of traditional PC resources and server resources, high operation and maintenance costs, low safety factor, etc. At the same time, it can make up for the lack of computing and storage capacity of terminal devices such as thin clients. Give full play to the advantages of mobile office. This paper first introduces the research status of desktop cloud, and describes the core concepts and technologies involved in the system, and then compares and analyzes the mainstream technology architecture of desktop virtualization at this stage. On the basis of the above technical theory research, the hybrid desktop cloud server end architecture is proposed and the core characteristics of the architecture are analyzed, and then the overall design of the architecture is carried out, including the overall architecture design. Logic architecture design, function structure and module design, as well as system core class diagram design, this part is the basis of the whole system construction. Then the problems in the architecture design are analyzed and the corresponding solutions are given, and the advantages of the solutions are explained. After completing the design of the hybrid desktop cloud server architecture, the fourth chapter of this paper further implements the whole system. From the point of view of function module, the system is designed and implemented in detail. Firstly, the related functions involved in the process of constructing data center are realized, including the dynamic join and exit of nodes, the calculation of data center capacity. And the design and implementation of physical resources pool and other functions. Then each sub-module of virtual machine management and virtual resource management is designed and implemented in detail. In addition, the design and implementation of the monitoring module and the service interface of the system are also completed. Then, the running effect and performance of the system are tested, and the test results are analyzed. In the last part of this paper, the full text is summarized and prospected.
