With Amazon AWS you can handle the scaling yourself, when you need it, with components tailored to your use cases, and better latency. And with Heroku you can have it taken care for you, following a few simple rules. So, why exactly would one use the crippled GAE platform, that constantly breaks its promises (re: reliability), forces you to code with very little flexibility (and, no, not every app that needs to automatically and massively scale "has to be coded exactly like a GAE app anyway"), costs a fortune (and sometimes an unexpected fortune), and breaks for you as soon as you need a technology not on offer?
