Heroku is another useful platform as a service offering built using AWS. Although, it uses a lot of ruby and essentially that is what it started with on the platform. But, it has steadily grown to support more add-ons and programming languages. It also has a very quick build/deployment approach compared to Google App Engine as well as a tight integration with Git. Setting things up on the platform is also very easy. And, free tier is unlimited to domains but has usage limits. The main drawback to the platform is that it can get very expensive very quickly once the data storage limits start being used with the add-ons and attaching additional for scalability. Perhaps, one has to weigh it out between whether to use Heroku, AWS, or both.
