【摘要】：云计算是目前计算机最为火热的研究领域之一，桌面云作为云计算中的一种，具有易于部署、安全性高和数据集中管理的特点。桌面云能将传统的桌面环境转移到数据中心，使其与终端设备解耦，用户能够使用瘦客户端等终端设备随时随地通过网络接入属于个人的桌面环境，提高办公的灵活性和资源的使用率。此外，桌面云解决了传统PC资源与服务器资源使用率低、运维成本高、安全系数低等问题，同时能够弥补瘦客户端等终端设备的计算和存储能力的不足，充分发挥移动办公的优势。本文首先对桌面云的研究现状进行介绍，并阐述了系统所涉及到的核心概念和技术，然后对现阶段桌面虚拟化的主流技术架构进行了对比分析。在完成以上技术理论研究的基础上，提出了混合型桌面云服务端架构并对架构的核心特点进行分析，然后对该架构的构建方式进行总体设计，包括整体架构设计、逻辑架构设计、功能结构与模块设计，以及系统核心类图的设计等方面，这部分内容是整个系统构建的基础。然后针对架构设计中引申出的问题进行分析和给出相应的解决方案，并说明所采用的解决方案的设计优点。在完成混合型桌面云服务端架构的设计后，本文第四章进一步对整个系统进行实现。从功能模块的角度对系统进行详细设计与实现，，首先实现构建数据中心过程中所涉及的相关功能，包括节点的动态加入和退出、数据中心容量的计算，以及物理资源的池化等功能的设计与实现。然后详细设计并实现了虚拟机管理和虚拟资源管理两大功能模块的各个子模块。此外，还完成了系统的监控模块以及系统的服务接口等部分的设计与实现。接下来，对系统的运行效果和性能进行了测试，并对测试结果进行了分析研究。在本文的最后部分对全文进行总结和展望。
[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.
