Kubernetes Autoscaling: Building Efficient and Cost-Optimized Clusters with KEDA and Karpenter

Tweet Mon 01 September 2025

I'm excited to share the news about my first upcoming book: "Kubernetes Autoscaling: Building Efficient and Cost-Optimized Clusters with KEDA and Karpenter" 🤩 ... this book reflects all the lessons learned after working with many, many customers around the world to build efficient Kubernetes clusters with Karpenter and KEDA. I can't count how many times I've talked about Karpenter already, but all those customer conversations have helped shape the content for this book.

The idea started as a focus only on Karpenter, but if we're honest, that's only one piece of the puzzle when we talk about autoscaling in Kubernetes. Therefore, I took on the mission to start with the basics so that we all understand why such tools exist today, and why it's important to know what impacts the performance of your application, its application patterns, and that rightsizing has a massive impact on efficiency. Moreover, as I really love getting hands-on, the book is packed with dozens of hands-on tutorials to help you learn by doing. So, if you're up with me in the mission of "saving the planet, one pod at a time," make sure you give this book an opportunity.

That being said, the book is soon to be published and it's ready for pre-order on Amazon and Packt. Also, if there's something you'd like to see in the book, there's still time to give me your feedback. So, please let me know either in the comments or message me; I'd be very interested to know what you'd expect to learn.
