Answer
HPA monitors CPU, memory, or custom metrics and adjusts replicas.
Quick Answer
HPA watches metrics (CPU usage, memory, custom metrics from Prometheus) and compares them to target values you define. If CPU usage exceeds 70% target across Pods, it increases replica count. If it drops well below, it scales down. It queries the metrics-server (or custom metrics adapter) and adjusts replicas automatically.
