1 Introduction to Kubernetes Autoscaling

Autoscaling is at the heart of an efficient and cost-effective Kubernetes cluster. Yet, many organizations struggle with resource management, often leading to significant financial waste or system failures. Understanding and implementing proper scaling can be the difference between a thriving, responsive system and one that's constantly on the brink of collapse.In this chapter, I'll introduce you to the concepts, strategies, and technologies surrounding autoscaling in Kubernetes, exploring its mechanisms, benefits, and challenges. You'll understand why scaling needs to evolve from a manual to an automatic process and how it has become an integral part of modern cloud-native architectures. I've worked with organizations that have achieved between 50% to 70% cost reduction in their compute expenses by making their Kubernetes clusters more efficient. This book aims to guide you on how you can achieve similar optimizations.In this...
