| With the continuing research on the cloud computing from the industry and academia, and the special concern of the market for IT management cost and green computing, desktop virtualization and desktop cloud has become another new technological innovations and market hot spots, which following the server virtualization in cloud computing field. Also, with the increasing scale of the research and investment market on virtualization, the desktop virtualization market of China will reach 5 billion yuan in 2014, and will grow rapidly according to the forecast.The cost of current solutions for desktop virtualization on the market is high and the management is complex, which not meeting the need of Chinese users. After the research of the demand of our market and specific national condition, this paper presents the virtual dynamic desktop cloud based on grid environment.The main innovations of this dissertation are as follows.(1)This papaer design the desktop cloud architecture based on grid.This kind of desktop virtualization solutions based on cloud, has the characteristics of high performance, low cost, simple management, to solve the traditional desktop cloud configuration management problems such as complex, high cost, not easy to extend.(2)This paper studies and implements the awareness of the state of the server,the virtual desktop instance and user domain in desktop cloud, and realize the data synchronization between the nodes in the distributed environment.(3)This paper designs and implements a simple and efficient virtual desktop management mechanism the mechanism which managens the instances of virtual desktops based on the "pool", generates virtual desktops based on the desktop template and realizes simple automated delivery features, also proposes the batch management algorithm and allocation algorithm of the virtual desktop which realizaing batch management of virtual desktops and user access management,which. |
