+Dynamic provisioning
+--------------------
+
+With dynamic provisioning,
+you do not have to create a PV object. Instead,
+it will be automatically created under the hood when you create the PVC.
+Kubernetes does so using another object called Storage Class
+
+
+A Storage Class is an abstraction that defines a class of backend persistent storage ,
+for example, `Amazon EFS file storage`, `Amazon EBS block storage`, etc. used for container applications.
+
+A Storage Class essentially contains two things:
+
+`Name`: This is the name, which uniquely identifies the storage class object.
+
+`Provisioner`: This defines the underlying storage technology.
+For example, provisioner would be `efs.csi.aws.com` for Amazon EFS` or `ebs.csi.aws.com` for `Amazon EBS`.
