The F5 iApp for Lync is a customizable extension of the BIG-IP platform for Lync that includes reverse proxy functionality. The operational integrity of iApps enables organizations to reduce common configuration errors by encapsulating all pertinent network settings for Lync into a discreet, manageable object.

If you recall, I am looking for a alternative solution to BIGIP F5 LTMs products. These products provide both high-availability fail-over via a Floating IP between LTMs, and the Load Balancing of requests to service endpoints. In the previous post, we managed to tackle the former part and provide High Availability, but not the Load Balancing part.

For example, Cisco Systems Inc. and F5 Networks Inc. offer such hardware (among others). However, in some situations, software-based load balancing is appropriate. For example, IBM's WebSphere Edge Components includes a Load Balancer module. In some environments, reverse proxy servers are useful.

What is the Reverse Proxy (httpd-accelerator) mode? Occasionally people have trouble understanding accelerators and proxy caches, usually resulting from mixed up interpretations of "incoming" and "outgoing" data. I think in terms of requests (i.e., an outgoing request is from the local site out to the big bad Internet). A reverse proxy acts as a middleman between users and an origin server. It’s a versatile tool that can perform a variety of functions, such as caching content for faster load times (thereby reducing server loads), distributing requests across servers, adding security checkpoints, and more.
