Event-driven architecture

How it is used

Common in distributed systems, integrations, and microservices. It fits workflows where actions happen asynchronously after state changes, messages, or user activity.

Example sentences

1. Our checkout service moved to an event-driven architecture, so inventory, billing, and email updates now react independently to each order event.

   Here the term shows that one order action emits an event, and several separate services handle their own follow-up work without direct coordination.

2. The team chose an event-driven architecture for audit logging because every account change needed to trigger records in several downstream systems.

   In this example, the architecture is useful because one change must notify multiple listeners that perform different logging or compliance tasks.
