Application Integration
CoreAmazon EventBridge
Managed event buses that route events from applications, AWS services, and partners to targets.
Key points
- Rules match event structure and decouple producers from target knowledge.
- Event delivery can retry, so targets should be idempotent and failures should have an explicit destination or recovery path.
- EventBridge is routing infrastructure; a durable worker backlog commonly uses SQS at the target boundary.
Best-known use cases
- Route events by source, type, or content.
- Integrate many event producers and consumers across accounts.
What candidates often confuse it with
- EventBridge excels at event-pattern routing; SNS excels at straightforward push pub/sub fan-out.
- EventBridge routes events; Step Functions coordinates explicit workflow state.
Key takeaway
Choose EventBridge when content-based event routing and producer/consumer independence are decisive.
