Amazon Lambda adds support for Rust in China Regions

Posted on: Nov 17, 2025

Amazon Lambda now supports building serverless applications using Rust in the Amazon Web Services China (Beijing) Region, Operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, Operated by NWCD. Previously, Amazon classified Rust support in Lambda as ‘experimental’, and did not recommend using Rust for production workloads. With this launch, Rust support in Lambda is now Generally Available, backed by Amazon Web Services Support and the Lambda SLA.

Rust is a popular programming language, offering high performance, memory efficiency, compile-time code safety features, and a mature package management and tooling ecosystem. This makes Rust an ideal choice for developers building performance-sensitive serverless applications. Developers can now build business-critical serverless applications in Rust and run them in Lambda, taking advantage of Lambda’s built-in event source integrations, fast scaling from zero, automatic patching, and usage-based pricing.

You can use the full range of Amazon deployment tools, including the Amazon CLI, Amazon Serverless Application Model (SAM), Amazon CDK, and Amazon CloudFormation to deploy and manage serverless applications written in Rust.
