OpenStack has several storage services, including:
- Cinder
- Glance
- Manila
- Ephemeral
- Swift1
Together these services provide virtual machines (VMs) with block, image, file share, and object storage. In turn, the services employ block, file share, and object storage subsystems. Since the service design has a mechanism to replace some or all of the implementation of these services, this solution can provide alternate implementations of these services that better serve your needs.
