Google App Engine and Amazon Web Services (AWS) are entirely different animals. So, comparing the two is not 100% straight forward; and I think that's on purpose. Amazon gives you one or more virtual computers in their "cloud" on demand along with services to accompany your virtual environment. Google App Engine, on the other hand is all about
just running applications; much of the details of how those applications are deployed and run is hidden from the end user/developer.
