In the previous chapter, we added some tools to our social media application to speed up developer time as well as to provide basic operational support features.

But nothing stands still. In various social media platforms, there is some form of messaging between the users. Why not create one for ours?

In this chapter, we will learn the following topics:

• Getting started with RabbitMQ, an AMQP broker
• Creating a message-based module for our social media app
• Adding customized metrics to track message flow
• Creating dynamically routed messages
• Taking a peek at Spring Cloud Stream and its RabbitMQ bindings
