Introduction
An event-driven architecture utilizes events to trigger and communicate between microservices. An event is a change in the service's state, such as an item being added to the shopping cart. When an event occurs, the service produces an event notification which is a packet of information about the event.
The architecture consists of an event producer, an event router, and an event consumer. The producer sends events to the router, and the consumer receives the events from the router. Depending on the capability, the router can push the events to the consumer or send the events to the consumer on request (poll). The producer and the consumer services are decoupled, which allows them to scale, deploy, and update independently.
