What is Heroku Enterprise?
Heroku Enterprise is similar to Force.com in that its primary purpose is to give developers the tools they need to build apps. The key difference is that Heroku is designed for the development and deployment of -cloudbased, external-facing, scalable apps for customers rather than employee-facing, internal apps.
Heroku Enterprise also allows developers to build in any programming language rather than just Apex, including Ruby on Rails, Node.js, Python, Java, and more. Heroku apps can run on any device and can link to social accounts so that customers can like, share, and take other public actions straight from the app.
