Horizon 7 supports Remote Desktop Services (RDS) hosts that provide RDS desktops and applications that users can access from Horizon Clients. An RDS desktop is based on a desktop session to an RDS host. In a typical Horizon 7 deployment, clients connect to desktops and applications through Horizon Connection Server. However, if you install View Agent Direct-Connection Plug-In on an RDS host, clients can connect directly to RDS desktops or applications without using Horizon Connection Server.
