An event driven architecture may be built on four logical layers, starting with the sensing of an event (i.e., a significant temporal state or fact), proceeding to the creation of its technical representation in the form of an event structure and ending with a non-empty … See more

Event driven architecture has two primary topologies: “broker topology” wherein components broadcast events to the entire system without any orchestrator. It provides the highest … See more

There are different types of events in EDA, and opinions on their classification may vary. According to Yan Cui, there are two key categories of events:
Domain Events
