Web apps are deployed seamlessly, monitored, and shared with other developers at the click of a button.

Earlier in this book, we focused on specific aspects such as building and deploying apps on the Heroku platform, and learned how various techniques can be employed to perform useful tasks with the platform.

In this chapter, we provide a round-up of everything we have learned so far. We will learn the following:

How to add Heroku support and deploy Java apps on Heroku using Eclipse
How to manage Heroku apps and perform all the app management operations inside Eclipse
