Cluster Autoscaler

Cluster Autoscaler is a system that automatically adjusts the number of servers (or nodes) in a computer cluster based on the workload. When demand increases, it adds more servers to handle the tasks; when demand drops, it removes unused servers to save resources. This ensures that applications run smoothly without manual intervention, optimizing performance and cost-efficiency. Essentially, it helps a cloud or data center dynamically allocate resources as needed, maintaining a balance between performance and expense without requiring constant human management.
