Lambda Durable Functions extend AWS Lambda into a platform for durable, long-lived workflows without custom orchestration code. Developers define “steps” for logic and retries plus “waits” for pauses such as human approvals, external callbacks, or AI agent processing.
The system automatically manages state, error handling, and recovery, with executions lasting up to a year while charging only for active compute and scaling to zero when idle.
Available via SDKs for Python and Node.js and deployable with SAM or CDK, Durable Functions are a key building block for enterprise-grade agentic workflows that span long-running business processes.
