Topologies and Components for IM and Presence

 

Topic Last Modified: 2010-10-07

The only components required for instant messaging (IM) and presence are:

• Your organization’s Front End Servers or Standard Edition servers. IM and presence capabilities are always enabled on these servers.

• A load balancer, if you have a Front End pool. You can use either a hardware load balancer for all load-balancing traffic, or use DNS load balancing for most of your traffic. For details about DNS load balancing, see DNS Load Balancing in the Planning documentation.
