VDI-Virtual Desktop Infrastructure
Virtual Desktop Infrastructure (VDI) is a desktop-centric service that hosts user desktop environments on virtual servers and/or blade servers, which are accessed over a network using a remote display protocol. A connection brokering service is used to connect users to their assigned desktop sessions. For users, this means they can access their desktop from any location, without being tied to a single client device. Since the resources are centralized, users moving between work locations can still access the same desktop environment with their applications and data. For IT administrators, this means a more centralized, efficient client environment that is easier to maintain and able to respond more quickly to the changing needs of the user and business or organization.
VDI is designed to deliver full desktop environments.
VDI implementations allow for delivering a personalized workspace back to a user, which retains all the user’s customizations. There are several methods to accomplish this.
One is to deliver fully persistent vm (virtual machine) desktops, in which a user gets a dedicated desktop that functions essentially as their own PC. Another mode is to deliver non-persistent desktops which do not include user personalization. These are vm desktops delivered from a pool which are then used for a session and returned to the pool. This approach has the advantage of keeping vm desktops “clean” as nothing is saved to the image by the user. Non-persistent desktops can be paired with user virtualization technologies to deliver user profiles and customizations (and all profiles settings, application data settings, configuration and user data), to the user upon login. The user profile is matched with a non-persistent desktop providing an experience that has very little difference from a PC. All changes made to the user profile are saved to the profile and are restored to the user upon their next login. However, the vm is returned to the pool with no changes saved to it.
