What is a StorageClass in Kubernetes?

A StorageClass in Kubernetes defines the parameters for dynamic storage provisioning. It acts as a blueprint for creating Persistent Volumes (PVs) based on the specified storage backend, such as AWS EBS, GCP Persistent Disks, or Ceph. StorageClasses allow for automation and flexibility in managing storage, enabling the creation of PVs on-demand as requested by Persistent Volume Claims (PVCs).

For example:

If you are running a web application and need storage for logs, you can use a StorageClass to dynamically provision storage on AWS EBS with specific performance characteristics, such as gp2 for general-purpose SSDs. When a PVC is created, Kubernetes automatically provisions the required storage using the defined StorageClass.

StorageClass Capabilities:

• Dynamic Provisioning: Automatically creates PVs when a PVC requests storage.
• Custom Parameters: Supports backend-specific…
