Our Amazon EC2 team uses Rust as the language of choice for new AWS Nitro System components, including sensitive applications such as Nitro Enclaves. Recently we launched Bottlerocket, a Linux-based container operating system written in Rust. But we also use Rust to deliver services such as Amazon Simple Storage Service (Amazon S3), Amazon Elastic Compute Cloud (Amazon EC2), Amazon CloudFront, Amazon Route 53, and more. Amazon’s first notable product built with Rust, Firecracker, launched publicly in 2018 and provides the open source virtualization technology that powers AWS Lambda and other serverless offerings. Here at AWS, we love Rust, too, because it helps AWS write highly performant, safe infrastructure-level networking and other systems software. Meanwhile in Redmonk’s rankings of programming languages, Rust has cracked the top-20, a significant feat given the staying power of Java, C, JavaScript, etc. For five straight years, Rust has topped Stack Overflow’s “Most Loved” programming language list, based on survey responses from more than 65,000 developers. Rust’s popularity growsĭespite only hitting version 1.0 in 2015, Rust has become exceptionally popular. In this post I’ll explain where (and why) AWS uses Rust, and how our contributions continue to evolve. In partnership with more than 5,500 contributors to Rust, we contribute in a variety of ways, all intended to enable AWS and others in the Rust community to build systems with confidence. This commitment has included code contributions to Rust and Tokio, a runtime for writing asynchronous applications with Rust, but our commitment to the Rust community goes beyond code.
As Shane Miller, Senior Software Engineering Manager at AWS, says, “Rust helps us deliver fast, robust services to AWS customers at Amazon scale,” and we’re committing to further strengthen a community that has greatly benefited us and our customers. Though AWS has benefited from Rust for several years, we’re looking for ways to contribute in meaningful ways. For similar reasons, at AWS we increasingly build critical infrastructure like the Firecracker VMM using Rust because its out-of-the-box features reduce the time and effort needed to reach Amazon’s high security bar, while still delivering runtime performance similar to C and C++. No one wants their electrical wiring to be exciting most of us prefer the safety that comes with being able to flip a switch and have light to see by. One of the most exciting things about the Rust programming language is that it makes infrastructure incredibly boring.
