AWS re:Invent 2022 - Rust is interesting, but does it really make sense for me? (BOA201)

Summary

Rust is a popular programming language known for its safety and control without a garbage collector or runtime.
It combines functional and imperative programming styles and offers features like pattern matching and memory safety.
Rust eliminates common bugs found in other languages and ensures memory safety, reducing the risk of severe CVEs.
It empowers teams to implement new technologies confidently and offers performance benefits.
Rust's strictness and learning curve can be challenging but lead to more robust and performant code.
AWS and Amazon have adopted Rust for various services, including CloudFront, Firecracker, and S3, due to its performance and safety benefits.
The speaker suggests starting with a small, well-understood project to evaluate Rust's fit for your team or organization.
AWS provides resources for Rust, including an SDK for AWS and a Rust runtime for Lambda.

Rust's safety features, such as preventing null pointer exceptions and iterator invalidation, can lead to more reliable software.
The language's strictness at compile-time forces developers to handle potential errors upfront, which can be frustrating but ultimately beneficial.
Rust's ability to work without a garbage collector or runtime can lead to smaller, more efficient applications, which is particularly beneficial in serverless architectures like AWS Lambda.
The adoption of Rust by AWS for critical infrastructure like CloudFront and S3 indicates a strong endorsement of the language's capabilities in high-performance and secure environments.
The speaker's strategy for introducing Rust involves starting with a small project to build confidence and demonstrate its advantages, which can be a practical approach for teams considering Rust.
The steep learning curve of Rust is acknowledged, but the speaker emphasizes that the benefits to end-users and service stability are worth the initial investment in learning the language.
