You learned the basics to get started with Heroku. You created your user account, learned how to install Heroku Toolbelt, how to create a Heroku application, and how to deploy your applications.

You also understood that Heroku needs three components to deploy: the source code, the dependencies file, and Procfile which describes what command should be executed to start your application.

So, the concepts learned in this chapter are fundamental to the rest of this book.

In the next chapter, you will learn about Postgres add-ons. You will create your first database and learn how to connect with different programming languages. In addition, you will learn about database permissions and monitoring.
