Scaling up a Serverless Web Crawler and Search Engine — Creating your own custom search engine can be both fun and useful (we have our own which helps us produce these newsletters!) but how could you approach crawling and indexing Web content in a serverless way? Here’s the basics of breaking down the main crawling process and how AWS Step Functions can orchestrate things.

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’.

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.

PHP Goes Serverless: Introducing the New Serverless LAMP Stack — The first in a new series of posts aimed specifically at PHP developers about how PHP can be used in the serverless context, not something we tend to see a lot about but AWS Lambda is certainly up to the task.

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 :-)

Decoupling Larger Applications with Amazon EventBridge — How to use an event-based architecture to decouple services and functional areas of applications. (EventBridge is AWS’s serverless app-to-app event bus.)

How to Use AWS Lambda Authorizers with Third-Party Identity Providers — A guide to using Lambda functions to secure API Gateway APIs by authorizing against third party identity providers using OAuth.

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.

Building a Serverless 'Weather Bot' with Two-Way SMS, AWS SAM, and AWS Lambda — Sending SMS text messages with Amazon SNS is easy, but did you know messages can go both ways? There’s quite a few moving pieces on show here but the end result is pretty neat with the technique easily applicable to other use cases.

How AWS Built a Production Service using Serverless Technologies — The creatively named ‘Realworld Serverless Application’ is a project inspired by Amazon’s work on the development of the Serverless Application Repository which itself is built as a production-grade serverless system. Trek10’s Forrest Brazeal also provides some analysis of AWS’s approach.

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.
