Question

A city 311 API spikes at lunch and should gain Pods when CPU is high. Which control plane object scales Deployment replicas from resource metrics like CPU?

Accepted Answer

HorizontalPodAutoscaler, which scales replicas from resource metrics such as CPU. — HPA is the thermostat for Pod count—when CPU heat rises past the setpoint, it spins up more replicas for 311. It is not a StorageClass or IngressClass job.

Answer

IngressClass, which selects an Ingress controller implementation.

Answer

StorageClass, which defines how PersistentVolumes are dynamically provisioned.

Answer

MutatingWebhookConfiguration alone, which admits object mutations but does not CPU-scale replicas.
