Enabling Application Request Routing for IIS Relay Server Hosts

Sybase recommends using IIS Application Request Routing (ARR) to balance request loads among IIS instances that host relay servers.

When you complete this task, your completed topology appears similar to this:

Like this image suggests, the first step in the task is to install and set up the IIS ARR controller. Continue all steps until your device client can connect to the environment using the ARR controller connection properties.

  1. Installing Required Microsoft Components
    Prepare a new standalone host by installing required components that make up the load balancer on supported Windows operating systems. Install only named components and install them in the documented order. Do not share this host with other Unwired Platform components.
  2. Configuring the Relay Server IIS Host for Load Balancing
    Update the configuration of the IIS Web server used by relay server already deployed to the DMZ so that load balancing operates correctly.
  3. Connecting Relay Server to the Application Request Routing Server
    The relay server needs to be able to receive in-bound client device requests from the ARR service. To enable that, you must identify the ARR host in the relay server configuration.
  4. Connecting Device Clients to the Application Request Routing Server
    With the ARR load balancer and relay servers set up and available, pass connection details to the developers responsible for configuring client device connection parameters.
