AWS Lambda Managed Instances now supports Rust

Posted on: Mar 13, 2026

AWS Lambda Managed Instances now supports Rust, enabling developers to run high-performance Rust-based functions on Lambda-managed Amazon EC2 instances while maintaining Lambda’s operational simplicity. This combination makes it easier than ever to run performance-critical applications without the complexity of managing servers.

Lambda Managed Instances gives Lambda developers access to specialized compute configurations, including the latest-generation processors and high-bandwidth networking. Lambda Managed Instances are fully managed EC2 instances, with built-in routing, load-balancing and auto-scaling, with no operational overhead. They combine Lambda’s serverless experience with EC2 pricing advantages including Compute Savings Plans and Reserved Instances. Rust support for Lambda Managed Instances combines these benefits with the performance and efficiency of Rust, including parallel request processing within each execution environment. Together, using Lambda Managed Instances with Rust maximizes utilization and price-performance.

Rust support for Lambda Managed Instances is available today in all AWS Regions where Lambda Managed Instances is available.

To get started with Rust on Lambda Managed Instances, see the Lambda documentation. To learn more about more about this release, see the release notes.
