# Event-Driven Architecture Event-driven architecture connects systems through events that indicate something happened or should be processed. Producers and consumers can remain loosely coupled. AutoSites' feed heartbeat is not a full event bus, but it performs a related coordination function: an external scheduler polls a declarative channel, and the feed probabilistically emits a transformed item for downstream automation.
