Storage providers

Kubernetes can use storage from a wide range of external systems. These will often be native cloud services, such as AWSElasticBlockStore or AzureDisk, but they can also be traditional on-premises storage arrays providing iSCSI or NFS volumes. Other options exist, but the take-home point is that Kubernetes gets its storage from a wide range of external systems.

Some obvious restrictions apply. For example, you cannot use the AWSElasticBlockStore provisioner if your Kubernetes cluster is running in Microsoft Azure.
