Good stuff
I've been using it for a little while, and I really like OpenShift. It's really simplified a lot of the bread and butter work that goes into deploying applications in stable, scalable, and above all, maintainable manner. I'm only using it for personal projects at the moment, but I can see how it would be really useful for all types of projects, ranging from the personal like mine, right up to the enterprise level.
Big thumbs up.
