This F5 deployment guide contains instructions on configuring F5 Global Traffic Manager (GTM) and BIG-IP Local Traffic Manager (LTM) modules to support site resiliency for Microsoft Lync Server 2010 and 2013.
Microsoft Lync Server supports DNS Load Balancing for distributing non-HTTP based connections to Lync Front End, Edge, and Mediation Servers. However, there are advantages to using the BIGIP system to load balance these connections in certain scenarios:
- You are using legacy clients or servers (Office Communication Server (OCS), pre-2010 SP1 Exchange Unified Messaging).
- You are federated with an organization using legacy clients or servers (see examples in the previous bullet) or public IM services/XMPP.
- You want to use intelligent logic (such as pool member status, least connection load balancing, and more) to make the initial client connection to the Front End, Edge, or Mediation pool.
- You want to use the F5 iApp template to deploy Lync Server rapidly.
- You use F5 GTM in your environment and would like to take advantage of F5’s Lync Site Resiliency solution.
The following diagram shows the configuration for external Lync clients described in the deployment guide.
