Configuring a High Availability Load Balancer for Apache / Windows


I'm currently trying to setup an environment where I have high availability even on the load-balancer. I have googled using multiple keywords, however all results that I got seemed to be tilted towards the LINUX/Debian world.

I'm on a windows environment, using Apache Server 2.2 with Tomcat 7. What I'm trying to get at is such that if a user visits my site and one of my load-balancer is down, I will still be able to serve my user.

As I'm a new user and will not be able to post photos, I've setup the photo at describing the network setup diagram. Thanks.

Appreciate any advice and sharings.

I'm not really sure what your question is about. In every case every single load balancer should reach both webserver. Are your load balancers are appliances?

There's a possibility to configure Apache with mod_jk or mod_proxy as an load balancer too. But I'm not sure if your question is about that. Please precise.
