RecognitionAWS Step Functions
Workflow alternative for multi-step automation; direct depth only when task-supported.
Key points
- Step Functions fits multi-step orchestration whose state and transitions must be explicit.
Best-known use cases
- D1.2 and D3.2: coordinate a named multi-step operational workflow when one runbook or event target is insufficient.
What candidates often confuse it with
- Step Functions maintains workflow state; EventBridge routes events, SNS publishes notifications, and SQS buffers messages.
Key takeaway
Use Step Functions only when the task requires workflow coordination rather than simple event delivery.
