Lambda on hard mode: serverless HTTP in Rust

The work around Rust and AWS Lambda integration makes it a joy to work with. Fast developer experience, fast and cheap runtime, when using rust in lambda it’s fast anyway.

Like yourself I use Axum, and pretend AWS lambda doesn’t exist. By default I use the standard HTTP server for local development, I then have an environment variable to toggle lambda mode for when running in lambda. If I wanted to I can run the app anywhere, lambda, ec2, eks, fargate, 3rd party vps/server.

Using Cargo Lambda and its associated AWS CDK plugin it cross compiles to ARM64, sets up AWS stacks with databases or other resources, removes a bunch of manual tasks.

The only thing that is inconvenient is you can not use custom domains for function urls. If you need a vanity name, you have to go via api gateway and associated costs. That’s by design though.

The monolith lambda works well. The KISS approach

Yep exactly how I do it. API gateway is such a pain, just to specify a default route pointing to the lambda. But it's a one time setup.
