Building distributed systems can be challenging, and that's what microservices are. With traditional request/response based architectures, it is easy to end up with services that are tightly coupled, making them difficult to maintain and extend independently. While not a silver bullet, an event-based architecture makes it easier to maintain loose coupling. It also makes it easier to extend and evolve our systems without resorting to a rewrite. In this presentation, we will look at an example of an event-driven microservices application and discuss some things to consider when adopting this approach.
