Last week Microsoft released a new version of the Office Communications Server 2007 R2 Workload Architecture poster. You can download it here (free, MS login required):
OCS 2007 R2 Workload Architecture Poster

The timing on this might seem odd. After all, we're charging full-on toward Lync Server 2010's release right?

Even so, this is a handy reference tool to have. For OCS 2007 and for Lync 2010.

The reason I say that is because it divides architecture up into four distinct functions: IM and Presence Workload, Application Sharing Workload, A/V and Web Conferencing Workload, and Enterprise Voice Workload.

Having these functions split up does several things for you:

  • Easy reference for discussion
  • Implementation aid if you don't use OCS
  • Troubleshooting aid if you do use OCS
  • Preparation for Lync

Now, the architecture in Lync Server is bound to differ from this. What I mean BY well, anyommunications system like Lync will need.”

Lync 2010 will need fewer servers than OCS 2007, to boot. So it should be a simpler architecture.

Familiarize yourself with OCS' architecture and be pleasantly surprised when Lync rolls out!

A couple additional points I want to make about the OCS 2007 R2 poster:

  1. Make a list of all the ports you'll need to use and keep it handy during implementation (OCS or Lync). Port collisions can cause a lot of trouble fast; head them off ahead of time.
  2. Note the positions of the hardware load balancers. There are that many for a good reason.
  3. If there's a part of this that will change the most in Lync Server, I'd say it's “Certificate Requirements.” Virtualization, altered server roles,and the integrated PBX capabilities will all change that.

I recommend this to all companies who use OCS 2007 right now,as well as any companies considering Lync Server 2010. Download and keep it handy!

Any other downloadable OCS/Lync resources you know of? Post them here and I'll highlight them in future posts.
