For a machine learning or NLP application -- Google App Engine vs Heroku vs App-fog

[Animesh Pandey via StackOverflow]

I have tried basic web applications on all the above three. If I were to rank them by convenience or freedom they provide then:

1. Google App Engine
2. App Fog
3. Heroku

But when the application domain became large the ranking actually changed. I am having huge troubles in using sklearn, nltk or gensim on GAE.

I am not very much experienced with Heroku and probably that is why I am having troubles in debugging errors where as GAE provides a console that really helps in debugging.

As far as app-fog is concerned it is pretty direct and to the point. But again what I noticed was that when I shared the link of the web-app almost everywhere it was being blocked by antivirus/firewalls!

Or maybe I am going wrong somewhere !

I need some suggestions please
