Research Of The Compound Desktop Virtualization Technology

Along With the increasing maturity of virtualization technology and its broad prospect, virtualization has become a research hotspot. Virtualization in general can be divided into server virtualization, network virtualization, storage virtualization and desktop virtualization. The first three kinds of virtualization, especially server virtualization, has been widely deployed in the IT Infrastructure, but with the extension of Virtualization technology to desktop computing field, desktop virtualization technology is also gaining attention recently.Compared with the traditional desktop environment, Desktop virtualization has follow key advantage: centralized management and delivery reduce the IT costs effectively and improve information security; at the same time, users can access the same and personalized computing environment everywhere, effectively improve the mobility.Most of the desktop virtualization solution is based on server virtualization (i.e. virtual machine technology). Poor extensibility and low level of resource utilization are the general shortcoming of most the desktop virtualization solution. This paper presents a compound desktop virtualization solution with involved virtual machine, remote desktop and cloud computing technologies. Our desktop virtualization has the following characteristics: 1. The applications from different platforms are integrated into a single desktop environment. 2. All the applications are packed into virtual machine templates, using SaaS technology, so the copyright can be effectively protected. 3. Only the related interface of certain applications is transferred, so reduce the network transmission. 4. Combined the technology of Remote Desktop and Virtual machine, our solution can enhance resource utility. In order to verify our desktop virtualization solution, we implement virtualized cluster management software: VE-manager and a load balancer: VE-Balancer; at the same time a front-end portal is implemented which is taking advantage of the web technology. All these modules are used to build a prototype system of compound desktop virtualization: VE-Desktop.
