I actually did some extensive work building a dedicated server using Bitnami's stack as well as Virtacore vCloud Express hosting. The final solution was very good and works awesome if you ant your own dedicated server. This is different than VPS with other providers in a sense as you have total control over the server stack.

Most recently I was also able to tag onto a buddy's CDN with MaxCDN so I could take full advantage of that as well as the OpCache which you get by having your own server.
