Hi, welcome to another weekly update!

Real-World Serverless podcast

Since the last update, we have had quite a few new episodes, covering a wide range of topics:

New blog posts

AWS Lambda Extensions: What are they and why do they matter. AWS announced Lambda extensions, and here’s my take on it and why it matters to you.

How to model hierarchical access with AppSync. In this post, I discussed an approach for modelling hierarchical access patterns where you have different groups of users with overlapping permission sets. Having dealt with this problem a few times, I arrived at an approach I find more manageable as the project grows.

How to set up custom domain names for AppSync. This is another common problem, and in this post, I discussed the two main approaches for setting up custom domain names for AppSync APIs.

How to sample AppSync resolver logs. AppSync’s resolver logs are very informative, but there are soooo much of it. Not having it in production is a shame, but leaving it to run 24/7 in production can be very costly. Instead, let’s see how we can implement some crude sampling instead.

What alerts should you have for Serverless applications?

How to debug slow Lambda response times.

This is all you need to know about Lambda cold starts.
