Application Integration
Amazon EventBridge
Amazon EventBridge routes events among AWS services, custom applications, and SaaS partners using rules and event buses. It decouples GenAI producers from asynchronous ingestion, evaluation, and remediation consumers.
Key points
- Rules match event patterns and send events to one or more targets
- Archive and replay support recovery and testing
- Delivery is at least once, so consumers must tolerate duplicates
When to use it
- Start RAG ingestion after an approved object event
- Fan out guardrail interventions to security and analytics workflows
Exam tips
- Select EventBridge for event routing; Step Functions owns multi-step state and SQS buffers work
- Use dead-letter queues and idempotency when downstream processing has side effects
