Architectural logic: Step Functions has native integrations—Lambda, Glue, ECS, SNS, SQS, DynamoDB, SageMaker, EventBridge. Each = Task state with service ARN and payload. Flow: Lambda validate → Glue ETL → Lambda write DynamoDB. Why: No polling; optimized integrations. Best practice: Map state for parallel; callback for long-running; X-Ray tracing.
Red Flag: Using Lambda to poll Glue job status instead of native integration. Pro-Move: 'We use Glue StartJobRun; callback pattern for completion—no polling, clean state.'
