Load balancing Microsoft Lync
About Microsoft Lync
Microsoft Lync and its client software, such as Lync 2013, enable your users to connect in new ways and to stay connected, regardless of their physical location. Lync and Lync Server bring together the different ways that people communicate in a single client interface, are deployed as a unified platform, and are administered through a single management infrastructure.
Users seek communications tools that make their work easier and are available anywhere, anytime – including within the context of other applications. Microsoft Lync provides a single interface that unites voice communications, IM, and audio, video, and Web conferencing into a richer, more contextual offering.
Key benefits of load balancing
Here are a few key benefits:
- Ensures the application is always available
- Provides a stable, optimal performance
- Ability to isolate servers which reduces risk when performing upgrades/maintenance
Microsoft’s Enterprise solutions are at the heart of businesses everywhere. Loadbalancer.org is officially certified for all of Microsoft’s key applications which you can find here. More details on the Microsoft Lync components, how it works, and prerequisites for load balancing can be found in our deployment guide, available to view below.
How to load balance Microsoft Lync
Deploying Microsoft Lync with Loadbalancer.org appliances enables organisations to create a feature rich highly resilient solution that ensures that wherever staff are located, and however they connect, they can depend on a platform that allows seamless communications wherever and whenever needed using the communications medium of their choice.
Loadbalancer.org appliances are configured to present a series of Virtual Servers (VIPs). These VIPs become the connection points for internal and external clients. The load balancer is then able to distribute requests to the Lync servers that make up the various pools.
Here’s an example deployment architecture:
Direct Routing (DR) mode a.k.a. Direct Server Return (DSR) mode is not supported for Lync. Instead, Layer 7 SNAT or Layer 4 NAT mode are be used.
Due to the number of Virtual Services (VIPs) required for load balancing Microsoft Lync, our R20 range is not supported. All other models can be used.
