The existing storage types available in our clouds are:

  • Volume storage: The standard storage unit for cloud computing; can be attached to and detached from an instance.
  • Ephemeral/Disk storage: Virtual local disk storage tied to the lifecycle of a single instance.
  • Object storage: Non-hierarchical storage where data is created or uploaded in whole file-form
  • Shared filesystem storage: Storage in the cloud shared filesystem; must be configured on each instance where it is mounted.

Attributes of each storage type are compared in the following table:
