Building resilient government workflows with AWS Lambda durable functions

This article introduces AWS Lambda durable functions, a code-first approach for building resilient government workflows that automatically checkpoint progress and survive failures without losing state.

• Durable functions extend Lambda with automatic checkpointing and replay, enabling workflows to run reliably for up to 1 year despite interruptions
• Provides durable operations including steps with configurable retry, waits without compute charges, callbacks for human-in-the-loop processes, and parallel/loop patterns
• Operates within existing Lambda FedRAMP authorization boundary and HIPAA eligibility with BAA support
• Eliminates need for custom state machines, polling infrastructure, and manual retry logic in government applications
• Ideal for child welfare case review, healthcare records requests, emergency services reporting, and benefits onboarding workflows
• Code example demonstrates document extraction, AI-powered analysis with Amazon Bedrock, and caseworker review callback
• Choose durable functions for code-first orchestration; use Step Functions for visual design and multi-service integration

Lambda durable functions provide government technology vendors a compliant, cost-efficient path to building mission-critical workflows without managing additional infrastructure.
