What Is Storage Class Binding?

A storage class describes a category of storage, such as SSD or HDD, along with its provisioner and reclaim policy. When a persistent volume claim references a storage class, the class dynamically provisions a matching volume and binds it to the claim. The binding mode can defer provisioning until a pod is scheduled so the volume lands in the right zone.

Why it matters

Storage classes let teams offer tiers of storage with different performance and cost without hand-creating volumes. Deferred binding avoids placing a volume in a zone where no pod can use it.
