Serverless and Edge Functions in Rust

Serverless computing lets you deploy Rust code without managing servers, scaling automatically in response to events. AWS Lambda and Cloudflare Workers are the two dominant platforms: Lambda executes compiled Rust binaries or WebAssembly on AWS infrastructure, while Cloudflare Workers runs Rust compiled to WASM on a global edge network with sub-millisecond latency. This series teaches you to build, optimize, and monitor production-ready serverless Rust applications.

You'll learn how to write Lambda handlers, reduce cold-start latency from seconds to milliseconds, compare native binaries versus WebAssembly runtimes, integrate with SQS and DynamoDB, and deploy with confidence using observability and security best practices. Whether you're building real-time APIs, background workers, or edge middleware, Rust's safety guarantees and performance make it an ideal choice for serverless workloads.

The progression moves from a quickstart (article 1) through core patterns and optimization (articles 2–5) to production readiness (articles 6–10). Start with article 1 if you're new to serverless Rust; jump to article 5 if you already know Lambda and want to compare runtimes.
