We’re seeing a bunch of these posts come around serverless around the time that we too are reconsidering our investment in this area. Lambda has a lot of operational benefits but at larger scales the developer experience just does not keep up.

A long post that builds up to async Rust from the ground up and explains how the various bits and pieces work. Really quite the tour de force with a simple conclusion: use Tokio.

With our re-evaluation of Lambda as a platform and after talking to some people, I’d say that Rust is the most (maybe the only) viable language on Lambda mostly because it’s negligible cold start times, high performance and the amazing developer experience of aws-lambda-rust-runtime.
