High availability virtual desktop infrastructure
A method for providing high availability Virtual Desktop Infrastructure (VDI) includes determining, by a VDI client and based on connection information for a first VDI broker associated with a first datacenter, whether a connection to the first VDI broker is available, and responsive to determining that the connection to the first VDI broker associated with the first datacenter is available, connecting the VDI client to a first VDI broker associated with a first datacenter. The method also includes sending authentication information pertaining to the user to the first VDI broker to authenticate the user through a domain controller, receiving, from the first VDI broker, a list of desktop pools available for one or more groups containing the user that has been authenticated with the first VDT broker, sending, to the first VDI broker, a desktop pool identifier associated with a desktop pool from the list of available desktop pools, receiving, from the first VDI broker, an address of a desktop selected from the desktop pool associated with the desktop pool identifier sent to the VDI broker, and providing the selected desktop to the user.

an agent associated with the primary data center upon which the virtual desktop of the user has been established:
monitors activity during a session associated with the virtual desktop of the user occurred with respect to the primary data center;
determines whether there has been no activity within the session or a predetermined time period; and upon a positive determination closes the session such that a user profile associated with the user can be synchronized.
4. A system providing a high availability Virtual Desktop Infrastructure (VDI) to a user, comprising:
a primary data center configured to provide virtual desktops to users; wherein
the primary data center establishes whether an event relating to a virtual desktop of a user has occurred;

a VDI database accessible by the VDI broker assigned to the corresponding data center configured to store global desktop pool configuration data, user group template data, and user desktops; wherein
the event is failure of a user to connect to a VDI broker assigned to the primary data center to establish the virtual desktop of the user;
the another virtual desktop for the user upon the secondary data center is established via the VDI broker assigned to the secondary data center receiving a request from an electronic device associated with the user;
