Microsoft Remote Desktop Services (RDS) is an industry leading desktop virtualization platform. It is the successor to Microsoft Terminal Services and facilitates the efficient, flexible and secure deployment of a Windows desktop environment and/or Windows applications, to users both locally and remotely.
Loadbalancer.org provides value-add by enabling scalability, high-availability and ease of management to users wishing to load balance their session hosts, connection broker with either session hosts or virtualisation hosts, session hosts with connection broker, gateways and web access servers depending on the infrastructure or operational requirements.
The load balancer is typically used to load balance multiple Connection Brokers, multiple Web Access Servers and multiple Gateway Servers. Session Hosts are normally load balanced by the Connection Brokers, although the load balancer can also be used as detailed in the deployment guide referenced below.
