#86: Serverless Testing

This week, we're diving deep into the world of serverless and exploring the latest techniques for testing and cost optimization. Are you tired of mocking AWS SDK calls when testing your serverless functions? We've got you covered with a new approach to serverless testing that doesn't require mocking. Plus, we'll show you how to keep your costs in check with serverless MongoDB Atlas.

But that's not all, have you ever wondered how a hacker can waste $13000 on your AWS account? We'll take a look at a real-life example and share the steps you can take to prevent this from happening to you.

We'll also explore some of the latest developments in Kubernetes, including a deep dive into DNS and service discovery and tips on how to detect insecure VSCode extensions. Additionally, we'll share some of our favorite open-source DevOps tools of the week and discuss the ongoing debate around Platform Engineering vs DevOps is Dead. Don't miss out on our coverage of finding active resources in your AWS account, building AWS Lambda layers with AWS CDK, and how to fix common issues in Kubernetes clusters.

I hope you enjoy this week’s newsletter! Share it with a friend or colleague if you find it helpful, drop me an email or send me a DM on Twitter about topics you’d like to hear about in future editions.
