Digest #159: SQLite vs. PostgreSQL, Kubernetes Cloud Savings, DeepSeek Data Leaks and Terraform Tools

How Kubernetes saved $3.9M a year, uncover DeepSeek data leaks, and explore tutorials on AWS EKS access, Git credential security, and advanced Terraform state management.

Welcome to this week’s edition of the DevOps Bulletin!

Ever wonder if SQLite or PostgreSQL is the better choice? This week, we share how Kubernetes cut our cloud spend, saved $3.9M a year, and revealed how the Wiz research team uncovered a leaking database. We look at a new CI/CD built for developers, see how Google keeps its cloud safe, and introduce Flox—a new tool to replace Docker with Kubernetes libraries.

In our podcast selection, listen to the wild tale of a penetration tester who accidentally robbed the wrong bank. Our tutorials cover topics like keeping your Git credentials safe, using AI tools as a staff engineer, and avoiding huge Terraform state files. We also highlight cool projects like Mathesar for managing Postgres data, a tool to explore SQLite pages, a web honeypot to fool attackers, an AI agent called Goose, and TerraConstructs, a new helper for Terraform.

All this and more in this week’s DevOps Bulletin—don’t miss out!
