Problem Statement
Describe how the Cluster Autoscaler works in Kubernetes and when you would configure it.
Explanation
The Cluster Autoscaler watches for unschedulable pods and adds new nodes automatically when resource demands exceed available capacity. It also removes nodes when utilization is low and pods can be safely evicted or moved. You configure it in cloud environments where node provisioning is dynamic and you want cost-efficient scaling based on real load rather than manual intervention.
