I've been fairly quiet on work and cloud activities recently because I've been flat out with planning. I don't think I've ever worked so hard in all my life nor enjoyed it so much. It's pure bliss.
As Mark says "A good Koala knows how to see the wood for the trees, even when her head is in the clouds. Ubuntu aims to keep free software at the forefront of cloud computing by embracing the API's of Amazon EC2, and making it easy for anybody to setup their own cloud using entirely open tools."
I couldn't be happier.
