Event-driven architecture is a software paradigm in which services and applications communicate asynchronously through publishing and consuming events. An event is anything that happens in a business environment or their customers’ ecosystem.

An obvious advantage is that services can be decoupled because of the asynchronous communication. This means they no longer need to rely on each other for scaling and don’t impact other services in case of failure.

Working with events also makes real-time data processing possible from several sources: not just software applications and services, but all kinds of IoT devices as well.
