CoreAmazon EventBridge
Event-pattern and schedule-based routing to pipeline targets.
Key points
- EventBridge starts targets from matching service events or schedules and routes pipeline state changes.
- A rule or schedule initiates work; it does not own a multi-step workflow's complete dependency state.
Best-known use cases
- Start pipelines on schedules or matching service events.
- Route data-arrival and job-status events to workflow targets.
What candidates often confuse it with
- EventBridge routes events or time-based invocations; Step Functions and MWAA coordinate stateful multi-step workflows.
Key takeaway
Choose EventBridge when an event pattern or clock should invoke a pipeline target.
