This was my second session presented at the Red Hat Forum in Tokyo, November 2012. There's a lot of animation in this presentation. The animation doesn't show well, but the basic ideas kinda show through. This presentation takes participants from a basic 1 or 2 node install to a Highly Available, Load Balanced, horizontally scaled deployment.
