AWS EKS Cluster Autoscaler Explained | How Node Scaling Works | Complete Demo

In this video, we deep dive into AWS EKS Cluster Autoscaler and understand how Kubernetes node scaling works in real production environments. We start by explaining what scaling is and why it is critical for production workloads. Then we explore how Cluster Autoscaler works internally, including pod creation flow, Kubernetes scheduler behavior, node groups, and Auto Scaling Groups (ASG). This session also covers how Cluster Autoscaler decides which node group to scale when multiple node groups exist. Finally, we perform a complete end-to-end demo using Terraform with full automation.
