Digest #176: AWS Account Wipe, Pinterest’s Kubernetes Bug, Kamal + Terraform Deployment
Git worktrees, AI-powered security forms, threat detection at Netflix, sharding explained simply, SQL-writing LLMs, and open-source gems like Hetty and MCDB.
Welcome to this week’s edition of the DevOps Bulletin!
This week, an engineer shared how AWS permanently deleted his 10‑year-old account, skipping their usual 90-day grace period. Pinterest revealed how a rare bug during their Kubernetes migration slowed a few requests by 100×. We also saw a neat trick with Git worktrees, how to automate security questionnaires using AI, and Netflix’s take on scaling threat detection pipelines without streaming. Don’t miss the free 340‑page DevOps handbook covering cloud-native setup, tuning, and CI/CD.
On the tutorial front, we break down database sharding in plain English, compare which LLMs write the best SQL, and walk through deploying an app with Kamal + Terraform on AWS.
Our open-source spotlight: MCDB turns Minecraft into a web server, Hetty is a Burp Suite alternative, Stasher CLI offers one-time secret sharing, and Application Inspector scans your code for useful features.
All this and more in this week’s DevOps Bulletin, don’t miss out!

📘 New Book: Practical FinOps (Now in Early Access)
The material comes straight from years of building a FinOps platform for Fortune-500 engineering teams, thousands of AWS, Azure, and GCP accounts, petabytes of data, and enough untagged resources to make a CFO cry.
Along the way, I kept a lab notebook of what actually worked and, more importantly, what didn’t. That notebook turned into this book.
