Serverless Rust: Building AWS Lambda Functions

Deploying serverless functions does not mean you have to sacrifice performance or pay high runtime costs. By combining the safety and speed of Rust with AWS Lambda, you can build incredibly fast, resource-efficient microservices. This text-based course guides you through the entire process of developing production-ready serverless applications. You will transition from understanding basic serverless concepts to writing, testing, and deploying optimized Rust functions that scale automatically. What you'll learn: Understand the core architecture of AWS Lambda and how Rust fits into the serverless ecosystem; Configure your development environment using Cargo Lambda to compile, run, and test functions locally; Write high-performance handler functions that process API Gateway events and interact with cloud services; Apply modern observability practices using structured logging and tracing to monitor your functions; Implement robust error handling and write automated tests to ensure code reliability; Deploy your compiled Rust binaries to AWS efficiently with minimal cold-start times. The course begins with foundational serverless concepts and Rust environment setup. You will then progress through writing your first function, handling events, integrating modern logging, and executing clean deployments. This course is designed for developers who are new to serverless development with Rust, with no prior cloud experience required.
