The cloud is all about elasticity and right-sizing. Microservice architectures are keen to be implemented in containers, and Kubernetes is arguably the most common orchestrator to run them. These containers, being (usually) stateless, are good candidates to use the cloud elasticity, so scaling them should be a well-known task. We'll talk about different scaling approaches and focus on Karpenter - the new group less cluster autoscaler, that can dramatically improve the efficiency and cost of running workloads on your cluster. You'll learn more about Kubernetes autoscaling, Karpenter features that allow right-sized scaling of EKS clusters
