The Horizon Gateway serves as the single namespace for all Horizon Workspace interaction and enables a user-facing domain for access to Horizon Workspace. It serves as the central aggregation point for all client connections, routes client traffic to the correct destination and proxies all requests. Horizon Workspace requires one Gateway-VA for every two data virtual appliances or one Gateway-VA for every 2,000 users.

Note: To provide high availability and improved scalability, multiple Gateway virtual appliances should be deployed behind a load balancer/reverse proxy. It is not supported to place Gateway virtual appliances in the DMZ.
