For a web project I'm working on, I will eventually need multiple servers with load balancing capabilities.
I figured buying a couple of RPis might be good practice. I've seen a few topics on setting up a RPi as a web server, but not multiple servers that are load balanced.
As for the physical setup, would I just use my home router/switch and assign a static IP to each RPi? Could I use one RPi to store the database, and then another RPi to run Apache and PHP? I've never really messed with multiple servers for a web application. I've always increased a single server's beef rather than add additional servers, and I'm just looking for a place to start.
