Horizontal Pod Autoscaling

Horizontal Pod Autoscaling is a feature in Kubernetes that automatically adjusts the number of active application instances, called "pods," based on current demand. If an application needs more resources due to increased traffic or workload, the autoscaler will create additional pods to handle the load. Conversely, if demand decreases, it can reduce the number of pods. This ensures efficient resource usage, maintains performance, and reduces costs by scaling the application up or down as needed, without manual intervention.
