AWS Lambda durable functions

Simplify building multi-step applications and AI workflows with familiar programming patterns in your preferred programming language.

Strengthen application resilience through built-in error handling, automatic retries, and recovery after failures.

Enhance operational efficiency by suspending and resuming executions during wait periods like human approvals, charging only for active compute time. Easily observe progress of your durable functions executions in the Lambda console.

Write, test, and debug durable functions using your preferred programming languages and tools.

Enable durable functions through a simple configuration setting when creating a Lambda function. Enhance your business logic with new Lambda event handler primitives like “steps” and “waits”.

Use “Steps” to checkpoint progress with automatic retries and recovery from the last known checkpoint.

Use "wait" and “callback” patterns to suspend execution for up to one year when waiting for external events, such as human-in-the-loop AI workflows or order processing.

Build resilient payment flows that maintain transaction state through failures and handle retries automatically. Coordinate multi-step authorization, fraud checks, and settlement across payment providers with full auditability across steps.

Create multi-step AI workflows that chain model calls, incorporate human feedback, and handle long-running tasks deterministically during failures. Automatically resume after suspension, and only pay for active execution time.

Coordinate order processing across inventory, payment, shipping, and notification systems with built-in resilience. Automatically handle partial failures, preserve order state despite interruptions, and efficiently wait for external events without consuming compute resources.

Build reliable workflows for employee onboarding, loan approvals, and compliance processes that span days or weeks. Maintain workflow state across human approvals, system integrations, and scheduled tasks while providing full visibility into process status and history.
