#94: Postgres Explained

Get ready for another action-packed edition of our weekly DevOps newsletter! This week, I'm covering a diverse range of topics that will help you level up your skills and stay up to date with the latest trends in DevOps. From exploring the ins and outs of Postgres architecture to learning how to troubleshoot common Kubernetes errors, I've got you covered.

Plus, we'll be diving into the world of AWS with articles on Just-in-Time Access and Serverless AWS CDK pipeline best practices & patterns. We'll also be discussing the importance of SREs being evangelists to be successful, and how to deal with devs pushing bad code to production.

And that's not all - I'm sharing open-source projects of the week, including a DevOps framework based on getting things done, APE, Troubleshoot, and Helicone. So, whether you're looking to automate your infrastructure with Terraform and Buildkite or learn how Discord stores trillions of messages, this week's newsletter has got you covered. Don't miss out - buckle up and let's dive in!

📖 POSTS OF THE WEEK

The unreasonable effectiveness of just-in-time access

📕 BOOK OF THE WEEK

I wanted to share a book I read last week called "Outliers" by Malcolm Gladwell. It's a fascinating read that explores the factors that contribute to extraordinary success.
Gladwell takes a deep dive into the stories of successful people like Bill Gates, The Beatles, and others, to uncover the unique circumstances and opportunities that helped them achieve greatness. He argues that success is not simply a matter of talent and hard work, but rather a complex interplay of opportunity, cultural legacy, and pure luck.
