Well I just successful got a primitive load balancing solution working on my development system. I'm working on getting it all figured out for my work so we can do more maintenance during the daytime without taking down the customers (since we need high availability).
Getting the basic load balancing working with Apache was relatively simple, now I need to get SSL working, sticky sessions, app distribution and all the other cool stuff figured out.
Pretty cool though, far more advanced than any other company I've worked for yet.
