AWS automation services: Step Functions, Lambda, EventBridge

Compose event-driven automation for ML operations.

What this covers

This guide compares capabilities, design patterns, and governance considerations when orchestrating ML automation on AWS.

Implementation trail

  • Event design principles
  • Service selection heuristics
  • Orchestration patterns
  • Security and governance
  • Cost and scaling

Design events as first-class contracts

  • Define event schemas with JSON Schema and publish them through EventBridge Schema Registry.
  • Version events and provide deprecation timelines to consumers.
  • Capture idempotency keys to prevent duplicate processing.

Pick the right automation service

  • Use Lambda for stateless, millisecond-to-minute tasks triggered by events or schedules.
  • Adopt Step Functions for long-running workflows, human approval steps, and error retries.
  • Rely on EventBridge as the decoupling backbone connecting services, SaaS systems, and custom applications.

Secure and govern your automations

  • Scope IAM roles per workflow and enforce least privilege on event buses and function invocations.
  • Enable CloudTrail data events and Step Functions execution logging for forensics.
  • Instrument DLQs and dead-letter buses to capture failures and trigger remediation automations.
