AWS Lambda durable functions are now available in 14 additional AWS Regions

AWS Lambda durable functions enable developers to build reliable multi-step applications and AI workflows within the Lambda developer experience. Starting today, durable functions are available in 14 additional AWS Regions: US East (N. Virginia), US West (Oregon), Europe (Ireland), Europe (Frankfurt), Europe (Milan) Europe (Stockholm), Europe (Spain), Asia Pacific (Sydney), Asia Pacific (Hong Kong), Asia Pacific (Tokyo), Asia Pacific (Singapore), Asia Pacific (Mumbai), Asia Pacific (Malaysia), and Asia Pacific (Thailand).

Lambda durable functions extend the Lambda programming model with new primitives in your event handler, such as "steps" and "waits", allowing you to checkpoint progress, automatically recover from failures, and pause execution without incurring compute charges for on-demand functions. With this region expansion, you can orchestrate complex processes such as order workflows, user onboarding, and AI-assisted tasks closer to your users and data, helping you to meet low-latency and data residency requirements while standardizing on a single serverless programming model.

You can activate durable functions for new Python (versions 3.13 and 3.14) or Node.js (versions 22 and 24) based Lambda functions using the AWS Lambda API, AWS Management Console, or AWS SDK. You can also use infrastructure as code tools such as AWS Cloud Formation, AWS Serverless Application Model (AWS SAM), and the AWS Cloud Development Kit (AWS CDK).
