Figure out how to serve an AWS Lambda function with a Function URL from a custom subdomain (via) This took me five hours and 77 issue comments to figure out, but I finally managed to serve an AWS Lambda function running Datasette on a custom subdomain with an HTTPS certificate. I was going to write this up as a TIL but I’m exhausted so I decided to share my private notes thread instead.
Deploying Python web apps as AWS Lambda functions. After literally years of failed half-hearted attempts, I finally managed to deploy an ASGI Python web application (Datasette) to an AWS Lambda function! Here are my extensive notes.
Abusing AWS Lambda to make an Aussie Search Engine (via) Ben Boyter built a search engine that only indexes .au Australian websites, with the novel approach of directly compiling the search index into 250 different ~40MB large lambda functions written in Go, then running searches across 12 million pages by farming them out to all of the lambdas and combining the results. His write-up includes all sorts of details about how he built this, including how he ran the indexer and how he solved the surprisingly hard problem of returning good-enough text snippets for the results.

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.
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.

New for AWS Lambda – Container Image Support. “You can now package and deploy Lambda functions as container images of up to 10 GB in size”—can’t wait to try this out with Datasette.

Serverless Microservice Patterns for AWS (via) A handy collection of 19 architectural patterns for AWS Lambda collected by Jeremy Daly.
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.

Statement Functions. Smart workaround for the lack of multi-line lambdas in Python.
