Compute
CoreAWS Lambda
Explicit automated remediation and event-driven automation surface.
Key points
- Lambda can execute event-driven remediation when the action, role, retry behavior, and postcondition are tightly scoped.
Best-known use cases
- D1.3, D2.1, and D3.1: run a bounded automation action in response to a supported event or operational condition.
What candidates often confuse it with
- Lambda runs code for an event target; EventBridge selects the event and Systems Manager Automation defines an operational runbook.
Key takeaway
Use Lambda for the stated code execution step, not as a substitute for event matching or runbook governance.
