Claim 2:
3. 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;
the primary data center upon a positive determination establishes another virtual desktop for the user upon a secondary data center which is configured to provide other virtual desktops to users.
each of the primary data center and secondary data center comprises a VDI database accessible by a VDI broker assigned to the corresponding datacenter; wherein
the VDI database is configured to store global desktop pool configuration data, user group template data, and user desktops;
the VDI databases of the primary data center and secondary data center are synchronized;
the domain controllers of the primary data center and secondary data center are synchronized;
replication between the VDI databases is performed after any commit operation in any of the VDI databases; and
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.
