This is something that is actually interesting to me. It does simplify the whole get a web service up part of development. The one thing that isn't touted enough on the page is how much this was brought about by interns. I hope those interns get some respect for something this functional and usable (I checked the MS Garage page and the team isn't even pictured, sigh).
This is an impressive engineering effort and really just a cool project, but most importantly to Microsoft, it's an excellent sales funnel for Azure.
