Amazon Lambda durable functions are now available in the Amazon Web Services China Regions
Amazon Lambda durable functions are now available in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD. Lambda durable functions enable developers to build reliable multi-step applications and AI workflows within the Lambda developer experience.
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 availability in the Amazon Web Services China Regions, 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.
You can 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 Amazon Lambda API, Amazon Web Services Management Console, or Amazon SDK. You can also use infrastructure as code tools such as Amazon CloudFormation, Amazon Serverless Application Model (Amazon SAM), and the Amazon Cloud Development Kit (Amazon CDK).
