To use a group of replicated Connection Server instances across a WAN, MAN (metropolitan area network), or other non-LAN, in scenarios where a Horizon deployment needs to span data centers, you must use the Cloud Pod Architecture feature.
This feature uses standard Horizon components to provide cross-data-center administration, global and flexible user-to-desktop mapping, high-availability desktops, and disaster recovery capabilities.
A typical Cloud Pod Architecture topology consists of two or more pods, which are linked together in a pod federation. Pod federations are subject to certain limits. The Cloud Pod Architecture feature can be used to connect pods running on-premises, on a public cloud, or a mix of both. For more information, see the Administering Cloud Pod Architecture in Horizon document.
