Why Use Rust for Serverless Workloads

Explore the advantages of using Rust for serverless workloads in this conference talk from Conf42 Rustlang 2023. Dive into an overview of AWS Lambda, including packaging code, memory and CPU allocation, and pricing. Compare the performance of Rust against Node.js and Go in serverless environments. Learn how to bootstrap a new Rust project for Lambda functions using cargo lambda, and examine sample code including handler and main methods. Discover the use cases for Lambda extensions, both internal and external, and their performance implications. Gain insights into writing efficient and sustainable serverless applications with Rust, complete with practical examples and performance considerations.
