Rackspace had a design summit last week in Austin, TX for Openstack. I was an attendee and learned quite a bit from the folks at Rackspace. They've built and re-built their infrastructure enough times they know what they need to look out for. The drop-and-swap component model is great too.

It was fantastic to see what they've put together and the business model is great. Commoditizing architecture and software really is the next step.

If anyone is interested, I could write up a blog post about my experience, maybe provide a little more insight into the buy-in.
