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:
