The Inner Works of an MMO Server Farm - This post, in which Spartikus3 discussed how MMO Rumble Fighter gold server farms work, has been up on our site for well over two years now.

Given the recent data center move Turbine made, and all the crazy talk flying around your Tubernets and Interthings, it may be a particularly relevant read. Especially this part:

Configuring servers the first time is tough. I've been there :) Optimizing the servers and software for maximum data throughput and performance levels takes time but once it is done, replication is accomplished in minutes / hours not in days or weeks.

Having a server farm of xxx servers, a good network team can configure the appropriate database/world servers in hours.

If release is a raging success and they STILL end up swamping their entire overflow pool of servers it's a matter of mere hours to load their software and configure NEW DB and world servers once they are made available from the service provider.

See, some people have been reporting an increase in lag since the move. And, while it's not really something Turbine like to see, it's something that ought to be expected.
