Persistent Volume
In plain terms
Cluster storage that outlives individual pods.
Going deeper
A PersistentVolume provides durable storage decoupled from pod lifecycles, so data survives pod restarts. It abstracts underlying storage.
Under the hood
Provisioned statically or dynamically via StorageClasses; claimed by pods through PersistentVolumeClaims.
Examples
Database storage, stateful apps, durable data, cloud disks in K8s.
Think of it like...
Like a storage unit that stays rented even as tenants (pods) come and go.
