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

Curious why some developers are using Nim instead of Python for data processing. Or how to set up cloud infrastructure faster (but maybe not the right way)? We also break down Kubernetes in a way that’s easy to understand, especially for beginners. Plus, we’ll walk you through recovering from accidentally deleting AWS roles and how Azure’s tools can help find security issues in Kubernetes.

We’ve also got tutorials on customizing Nginx logs, using Python virtual environments in Docker, and how to achieve zero-downtime deployments on AWS.

On top of that, check out cool new DevOps projects like Tfreveal for better
