#104: Testing CloudFormation Stacks

This week, I've scoured the web for the most insightful articles, practical guides, and open-source projects to share with you.

Let's begin by understanding how to optimize DynamoDB costs with a few practical examples. There's also an intriguing discussion on why engineering for 99.5% uptime might be more cost-effective than 99.99% for most startups. Let's explore this debate together.

I've found a tested way to organise folders and structure environments in Terragrunt. Moreover, there's an interesting guide on building a Serverless data processing flow using Kinesis Data Firehose and Terraform which you should definitely check out.

GitOps has been making waves recently, and I've found a fantastic hands-on guide featuring Flux, Flagger, and Linkerd. Also, I've found an insightful post-mortem of Datadog’s $5M outage, a worthy read to ensure such expensive mistakes aren't repeated in your own systems.

Are you considering migrating from Supabase? A real-life migration story will provide you with valuable insights and lessons learned. It's definitely a must-read!

For the open-source project highlights this week, I'm excited to introduce Cloud-Radar, a Python module for testing Cloudformation templates/stacks; Terrap, a CLI tool that scans your infrastructure and points out necessary changes; and Sniffnet, an application designed to conveniently monitor network traffic. These are all fantastic additions to your DevOps toolbox.

Happy reading!
