A Service Based Lightweight Desktop Virtualization System

Desktop virtualization is a new delivery method in which desktop operating systems execute in a data center and users access their applications using stateless "thin-client" devices. This paradigm promises significant benefits in terms of data security, flexibility, and reduction of the total cost of ownership. It is important to further improve this approach while maintaining good user experience, decreasing the propelled desktop\´s granularity and optimizing the protocol utilized between clients and servers. In this paper, we build a feasible cloud computing system, in which application streaming technology is used to break the bottleneck between clients and computing resources, and at the server side, virtualization technology is utilized to help achieve better physical resource management, as well as the high performance virtualized storage system. Simulations show that the proposed system greatly improves the QoS of users and efficiently allocates resources among all clients.
