The Design And Implementation Of Public And Private Mixed Storage System In Cloud Desktop Environment

With the continuous development of computer hardware technology and the continuous improvement of user's usage mode of traditional PC,desktop virtualization technology is gradually perceived by people.Users can access their own virtual machines through the network,with the same user experience of accessing the traditional PC.However,when desktop virtualization brings us a convenient and comfortable use experience,there are still some significant problems.While users are in the use of virtual hosts,data storage location is still stored in the public storage of the virtual host server,that is to say,the user is unable to manage their own datas,where exists the problems of data visibility and security.In today's information society centered on data security,how to solve the problem of data security and privacy issues become the most urgent and the most concerned needs of users.In this thesis,the above problems are studied and analysed,and a kind of publicprivate mixed storage system is proposed and implemented.The system is based on virtual cloud desktop environment,built by the XenServer virtual server with XAPI and self built Ftp file cache server,and uses some kinds of computer technology such as MYSQL,Socket,FTP and so on.By the client module,users can register and login in,detect the private storage device under the current environment and input the VM parameters to initialize.With the connection of client and server,users can manage their virtual machine data stored on the public storage area of the virtual server.The system can also transfer user's datas to their own private storage areas,when the user is online again,the user's datas can be migrated back to the virtual machine from the private storage area again.At the same time,it can also carry out the data monitoring and scanning dynamically,and when the user is offline,the data can be backed up to the private storage,which ensures the data visibility and data storage security.Finally,through the practical application environment,the system is tested and analyzed effectively to ensure the validity and reliability of the system.
