What storage types are allowed by OpenStack Compute?

Two types of storage are supported by the OpenStack Cloud Operating System:
Persistent Storage: User-created persistent storage that is independent of any given instance. This also contains three storage areas:

  • Object storage: using the REST API to access binary items.

  • Block storage: By affixing volumes to their present VM instances, block storage provides access to block storage devices.

  • Shared File System storage: provides a collection of services for storing and exchanging numerous files with multiple users at the same time.

  • Single-instance storage is referred to as ephemeral storage. These storage choices are transient and short-lived, as the name implies, and they vanish once the VM is stopped.
