Anyone doing this? Recently been playing with RackSpace's Cloud Servers and have a dedicated web server with 2GB of memory and a Dedicated MySQL server with 1GB of memory. Works fine for my current low volume sites but I am about to put a larger site on them and was going to use elasticsearch on it. I can easily add a third server with 512MB of memory dedicated to just running search if it would make a difference? Basically trying to keep everything as separate as I can so I can easily tell which is the most resource intensive for all my sites.
