Unified Access Gateway is typically deployed in a DMZ. For high availability and scalability requirements in a production deployment, several Unified Access Gateway appliances are usually set up behind a load balancer as shown in Figure 3-1. The LoadMaster is deployed in-line as a proxy for all services including PCoIP. Alternative deployment options could have the secondary Horizon protocols bypass the LoadMaster as it is only the initial session establishment (HTTPS) that can be load balanced.
