"Google entered game early in 2008 with App Engine. Very powerful" Empirical observations show that Google never managed to (or never tried to) make App Engine meet the general customers' needs for building their applications. Of cuz, that does not include Snapchat. Is it because Google did not invest enough, or Google failed to educate and/or engage developers, or Google made a wrong assumption that App Engine would eventually catch up, there is no clear answer. So overall, I do not think App Engine is 'powerful'. Sure, it has fancy feature and advanced designs. But that does not make something powerful. A powerful tool is one that help users do more with higher efficiency, or enable users to do things that otherwise is impossible or too costly. App Engine might be able to do that, but it was not proved to be true in general.
