Using an F5 LTM Load Balancer for Reverse Proxy with Lync 2013

6 Comments

Ok, I couldn’t resist it… In my previous blog I wrote about publishing Lync services using a Kemp Load Master. Since I’m not married to Kemp (although you might think differently, and so does Marco 😉 I also have an F5 LTM up-and-running in my lab. Time to have a closer look at the F5 when it comes to reverse proxy with Lync 2013.

Lync Configuration

Again, in my lab I have a Lync 2013 Enterprise Edition, in the perimeter network I have a Lync 2013 Edge Server, but I will use an F5 LTM load balancer.

Using a Kemp Load Balancer for Reverse Proxy with Lync 2013

In my previous blog I wrote about publishing Lync services using IIS/ARR as a replacement for TMG 2010. It is also possible to use a hardware load balancer to publish these Lync web services to the internet. In this blog I’ll talk about using a Kemp LoadMaster LM2600 for publishing Lync web services.

Using ARR for Reverse Proxy with Lync 2013

15 Comments

In an earlier blog post I wrote about publishing Lync services using TMG 2010. One of the Microsoft alternatives for reverse proxy is the Application Request Routing module or ARR, a module that’s running on top of Internet Information Server (IIS).

Lync Webinar 12 maart 2014

Leave a comment

Op 12 maart 2014 heb ik mijn eerste Lync presentatie gegeven, en ook nog in het Nederlands. Dat laatste was wel prettig. Ook de eerste keer voor mij in het Nederlands.

De presentatie ging over Load Balancing Lync 2013 (georganiseerd door Kemp) en gezien de reacties ging het niet slecht. Zelf heb ik wel een aantal punten waar nog wat aandacht aan besteed moet worden (bijvoorbeeld ‘draining’) maar dat komt in een toekomstige blog wel.

De vervolgstappen zijn een algemene Load Balancing presentatie en een presentatie over Load Balancing Exchange 2013. Gezien de hoeveelheid mensen die aangemeld (en aanwezig!) waren worden beide presentaties weer in het Nederlands gehouden.

Heb je nog aanvullende vragen of onderwerpen voor een toekomstige blog, je kan me vinden op Twitter via @jaapwess of mail me op mail[at]jaapwesselius.com.

De presentatie is hier te downloaden: https://jaapwesselius.com/wp-content/uploads/2014/10/lyncwebinar-12maart2014.pdf

Load Balancing Office Web Apps 2013

2 Comments

In an earlier blog post I explained how to install and configure Office Web Apps 2013 in combination with Exchange Server 2013. This blog post only explained how to create an Office Web Apps farm on a single server. This blog post will explain how to create additional servers and use a load balancer in front of multiple Office Web Apps 2013 servers using SSL Offloading

SSL Offloading

Microsoft recommends using SSL Offloading when configuring a load balancer in front of an Office Web Apps farm so we need to configure this first.

My original blogpost was about a WebApps server that had a dedicated Internet connection. This is now changed to a WebApps server that is only connected to the internal network. The Internet connections will enter the load balancer and the WebApps server is configured as a real server in the load balancer’s VIP.
