AWS Lambda Managed Instances Now Supports Rust

AWS Lambda Managed Instances now supports Rust, allowing 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 to run performance-critical applications without managing servers.

Lambda Managed Instances provide access to specialized compute configurations, including the latest-generation processors and high-bandwidth networking. These instances are fully managed EC2 instances with built-in routing, load-balancing, and auto-scaling, offering 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.
