When installing replicated Horizon Connection Server instances, you must usually configure the instances in the same physical location and connect them over a high-performance LAN. Otherwise, latency issues could cause the View LDAP configurations on Horizon Connection Server instances to become inconsistent. A user could be denied access when connecting to a Horizon Connection Server instance with an out-of-date configuration.
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 datacenters, you must use the Cloud Pod Architecture feature. You can link together 25 pods to provide a single large desktop brokering and management environment for five geographically distant sites and provide desktops and applications for up to 50,000 sessions. For more information, see the Administering Cloud Pod Architecture in Horizon 7 document.
