DevOps Bulletin - Digest #99: Scaling to 1000 K8s Pods 😳

#99: Scaling to 1000 K8s Pods
Hold on to your keyboards, the latest DevOps weekly digest is here and it's packed with content 😅

Embark on a developer's voyage to AWS Lambda mastery, and fine-tune your pull request game with writing tips that'll make your team productive. We'll also delve into setting up event-driven, trace-based testing in Kubernetes and present the ultimate guide to load balancers.

Ever wondered how HTTPie lost 54k GitHub stars? I've got the scoop! Discover why one team ditched RabbitMQ for a Postgres queue, and learn valuable lessons from scaling a Kubernetes cluster to a whopping 1000 pods.

As always, I've handpicked some outstanding open-source projects for you to explore. KubeStalk unveils Kubernetes and related infrastructure attack surfaces from a black-box perspective. Unleash powerful search, tagging, filtering, and sorting capabilities for SQLite databases with a simple text query language. And don't miss the open-source database package registry for Postgres, taking your DB game to the next level.

Plus, I'm hosting a free workshop this Wednesday on Discord about building a Jenkins cluster on AWS from scratch with Terraform and Packer - Join the event here.

This week's DevOps digest is bursting with insights, so don't let it slip away!
