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

Wondering how Uber managed to reduce their log size by 99%? We’ll break down the clever approach they used to cut storage costs. Thinking about switching databases? We’ve got insights on migrating from PostgreSQL to MySQL without starting from scratch.

You’ll also learn why discussing action items during incident reviews might not be the best idea and why giving incident resolution estimates could lead to trouble. If you’re into serverless development, see how you can speed things up by emulating AWS locally with LocalStack and Terraform.

Python fans, we’re exploring if uv’s managed Python is the right fit for your production environment. Plus, find out how a 15-year-old hacker uncovered on Zendesk.

And don't miss the highlight of some cool DevOps tools, from a simple SSH tunnel manager to a tool that anonymizes your PostgreSQL databases.

There’s much more to discover this week, including managing Docker image sprawl and how to automate TLS certificates with AWS Lambda.
