Memory hook

AWS Step Functions = Uses state machines to coordinate Lambda, service calls, and short- or long-running workflows.

Update: orchestration boundaries

  • A state machine models sequence, choice, parallel, wait, retry/catch, and callback or human approval.
  • Step Functions orchestrates work; it does not execute application code. Lambda, ECS, APIs, or other services perform the computation.
  • Retries should separate transient from permanent failures, while catch paths lead to compensation, manual handling, or a DLQ.
  • Long workflows need explicit idempotency, execution history, timeouts, compensation, and sensitive-data boundaries.
