Learn how to maintain the health of your Elixir application in production by using key components of a real-time stack.

Become an Elixir Professional

In this module, we'll first learn how to build real-time applications that are fast and employ few resource overheads. Today’s software users expect the data on their screens to reflect instantly. We'll learn to win our users’ trust by giving them a seamless application experience powered by real-time features. Then we'll focus on the essential part of the real-time stack (Elixir, Phoenix channels, websockets, and GenStage). We'll also learn to work with some of the more advanced features of Phoenix, such as Phoenix Tracker. Finally, we'll look at how to keep our application healthy and happy in production.
