A message from our sponsor, incident.io:
We’ve just raised $62M at incident.io to build AI agents that resolve incidents with you. See how we’re pioneering a new era of incident management.
In this final installment of the Scaling Nextdoor’s Datastores blog series, we detail how the Core-Services team at Nextdoor solved cache consistency challenges as part of a holistic approach to improve our database and cache scalability and usability.
I really enjoyed this whole series. Thanks, Nextdoor folks!

In this article, I’ll walk you through how we implemented chaos engineering across our stack using Chaos Toolkit, Chaos Monkey, and Istio — with hands-on examples for Java and Node.js. If you’re exploring ways to strengthen system resilience, this guide is packed with practical insights you can apply today.
The author does not appear to have a tie to Istio. This article has a ton of code snippets to help you get started.

In this blog, we’ll look at three important facts about serverless reliability that teams often overlook. We’ll explain what they are, what the risks are of not addressing them, and how you can make your serverless applications more fault-tolerant.

- You do have control over serverless reliability.
- Serverless reliability practices can benefit all platforms, not just serverless platforms.
