Application Integration
CoreAmazon EventBridge
Serverless event bus and routing service that matches events to rules and sends them to targets.
Key points
- Event patterns route matching events by content; schedules can initiate time-based events.
- Producers do not need to call every target directly.
- Targets require the correct invocation permissions, input shape, retry, and failure handling.
Best-known use cases
- Content-based application event routing.
- Integration with AWS service and custom application events.
What candidates often confuse it with
- EventBridge routes events by rules; SNS performs topic-based pub/sub fanout.
- EventBridge choreography differs from Step Functions stateful workflow orchestration.
Key takeaway
Choose EventBridge when rules should route events without hard-coded producer-to-target calls.
