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

Serverless Microservice Patterns for AWS (via) A handy collection of 19 architectural patterns for AWS Lambda collected by Jeremy Daly. # 12th June 2019, 12:13 am

Client-side instrumentation for under $1 per month. No servers necessary. (via) Rolling your own analytics used to be too complex and expensive to be worth the effort. Thanks to cloud technologies like Cloudfront, Athena, S3 and Lambda you can now inexpensively implement client-side analytics (via requests to a tracking pixel) that stores detailed logs on S3, then use Amazon Athena to run queries against those logs ($5/TB scanned) to get detailed reporting. This post also introduced me to Snowplow, an open source JavaScript analytics script (released by a commercial analytics platform) which looks very neat—it’s based on piwik.js, the tracker from the open-source Piwik analytics tool. # 15th March 2019, 4:03 pm
