Event-Driven Architecture
An architecture where components publish and react to events about state changes.
Plain English
Parts of the system respond when something happens.
In context
Event-driven systems decouple producers from consumers but add ordering delivery and observability concerns.
Example
“Order creation emits an event that starts fulfillment.”
