Conguring Load Balancing

When you use WDM to manage thin client devices in a very large enterprise environment, a single WDM Management Server cannot

scale up to manage the large number of devices. There could be problems or delays in client check-ins, schedule execution, or real-

time command execution.

Load balancing helps resolve these problems to a great extent. In this setup, you can install and run multiple instances of WDM

Management Servers on dierent systems and congure the load balancing feature between them. WDM uses the Microsoft

Application Request Routing (ARR) for IIS 7 feature to perform load balancing between the management servers. This section

describes how to setup and congure load balancing.

Setting up the ARR Proxy Server

The Application Routing Request (ARR) Proxy server is the most important component of Load Balancing. This server receives the

requests from the thin client systems and routes them to the dierent WDM Management servers.

Before you set up the ARR Proxy server, you must make sure of the following:

• The entire setup should be on Windows 2008 Server R2 or higher.

• Install all the components of WDM on one server.

• Install only the WDM Management Server and ThreadX 4.x service on another server.
