Connection Server instances in a Cloud Pod Architecture environment use shared global entitlement and topology configuration information from the Global Data Layer to determine where to search for and how to allocate desktops and applications across the pod federation.
When a user requests a desktop or application from a global entitlement, Horizon searches for an available desktop or application in the pools that are associated with that global entitlement. By default, Horizon gives preference to the local pod, the local site, and pods in other sites, in that order.
For global desktop entitlements that contain dedicated desktop pools, Horizon uses the default search behavior only the first time a user requests a desktop. After Horizon allocates a dedicated desktop, it returns the user directly to the same desktop.
You can modify the search and allocation behavior for individual global entitlements by setting the scope policy and configuring home sites.
