aws-lambda-adapter. AWS Lambda added support for Docker containers last year, but with a very weird shape: you can run anything on Lambda that fits in a Docker container, but unlike Google Cloud Run your application doesn’t get to speak HTTP: it needs to run code that listens for proprietary AWS lambda events instead. The obvious way to fix this is to run some kind of custom proxy inside the container which turns AWS runtime events into HTTP calls to a regular web application. Serverlessish and re:Web are two open source projects that implemented this, and now AWS have their own implementation of that pattern, written in Rust. # 28th October 2021, 5:04 am

Behind the scenes, AWS Lambda (via) Bruno Schaatsbergen pulled together details about how AWS Lambda works under the hood from a detailed review of the AWS documentation, the Firecracker paper and various talks at AWS re:Invent. # 10th July 2021, 7:40 pm
