Introducing AWS Lambda Extensions (in Preview) — A mechanism to deeply integrate Lambda with monitoring, observability, and security tools (e.g. Epsagon, Hashicorp, other AWS tools).

Scheduling AWS Lambda Provisioned Concurrency for Recurring Peak Usage — The concurrency of an AWS Lambda serverless function is the number of requests it can handle at any given time, and while serverless is designed to flexibly scale, you might want to use provisioned concurrency to avoid ‘cold starts’.

A Crash Course on Using AWS CDK for Data Work — AWS’s Cloud Development Kit (CDK) makes it possible to define cloud infrastructure in code and provision it with CloudFormation. This article looks at the basics of using it to create a serverless app for querying different data systems.

You Can Now Mount a Shared File System in AWS Lambda Functions — This is one of those things that’s a huge deal if you do serverless, and perhaps harder to understand if you don’t, but you can now mount Amazon Elastic File System (EFS) file systems in AWS Lambda functions which opens up a lot of new use cases.

How to Build a Serverless Martian Weather Display with CircuitPython and AWS Lambda — No lie, this tutorial compelled me to buy my own PyPortal last week. Neat device.. has wifi, can load stuff from the Web, basically a 3.2” screen you can code with Python :-)

Introducing a Dart Runtime for AWS Lambda — Dart is a popular general purpose language originally built by Google as a sort of more structured JavaScript replacement but which is now finding its own niches.

AWS Serverless WebSockets — Introduction Around the Pitfalls — I’ve played briefly with API Gateway’s WebSockets support and was impressed, but there are a lot of moving parts to take into account when actually using it.

From Poll to Push: Transform APIs using Amazon API Gateway REST APIs and WebSockets — I’ve been playing with API Gateway’s new(ish) WebSockets support and it opens up some really neat architectural patterns, as seen here.
