AWS Lambda Durable Functions in European Sovereign Cloud

AWS Lambda durable functions are now available in the AWS European Sovereign Cloud, enabling developers to build reliable multi-step applications and AI workflows. These functions extend the Lambda programming model with new primitives like "step" and "wait", allowing for checkpointing, automatic recovery from failures, and pausing executions without incurring compute charges for on-demand functions.

What to do

  • Activate durable functions for new Python (versions 3.13 and 3.14), Node.js (versions 22 and 24), or Java (17+) based Lambda functions using the AWS Lambda API, AWS Management Console, or AWS SDK.
  • Use infrastructure as code tools such as AWS CloudFormation, AWS Serverless Application Model (AWS SAM), and the AWS Cloud Development Kit (AWS CDK).
