You can use either a software or a hardware load balancer to get the best performance out of your Relay Servers.
If you are using only a single Relay Server, skip this topic.
You should be able to use any hardware or software load balancer that you prefer with the Relay Servers you have installed to support your Unwired Platform cluster. This document describes use of Apache 2.2, with proxy load balancing.
If you are using a hardware load balancer, see the product documentation for instructions on setting it up.
If you are using a software load balancer other than Apache 2.2, see the program documentation for instructions on setting it up
