This is cool. We currently host our app with Engine Yard and there's been a number of times when we've wanted to put in extra capacity for short bursts but it's impractical to do it. It's not the cost of upgrading for me that's the problem but the hassle of having to configure a new instance, and migrate to it. So I love the approach of dragging a few sliders and it magically happening. Go GoScale :)
