The Inner Workings of the Event-Driven Architecture Pattern

We have covered the basic architecture. Now we look at how the parts behave in a running system.

Event Generation and Propagation

The life of an event starts with a change in state in the system. This could be a user action, a sensor reading, or even an internal system update. An event is then generated to encapsulate this change in state. But how does this process occur?

Event Producers are responsible for generating these events. In essence, an event is a bundle of data representing a significant occurrence in the system
