The following are some variations of remote virtualization technologies

Application Virtualization

Application virtualization aims to solve the problems of compatibility, deployment and updates as well as administration and desktop management. In this approach, programs actually execute on the client.  There are considerable benefits to using application virtualization. Applications can use the processing power on desktop machines, and users can interact with applications locally (as their developers intended). Administrators benefit from being able to centrally manage their applications and can control who can access them. This aids in improving security and measuring license usage.

Desktop Virtualization (Virtual Desktop Infrastructures)

Another concept is of desktop virtualization. This approach goes by various names (for example, VMware calls its approach VMWare View). The idea here is that all data, operating systems, and applications will run within the confines of the data center, while users will access their personal VMs over a network connection. This increases security and can potentially reduce desktop management (especially if clients are using diskless/stateless computers). Virtual Bridges, Ulteo Virtual Desktop, VMWare View and XenDesktop
