Object Storage Deployment

Fuel currently supports several scenarios to deploy the object storage:

Glance + Ceph: Ceph can be used as an object storage option for Glance.
Glance + filesystem: By default, Glance uses the file system backend to store virtual machine images. In this case, you can use any of shared file systems supported by Glance.
Swift on controllers: In this mode the role of swift-storage and swift-proxy are combined with a nova-controller. Use it only for testing in order to save nodes. It's not suitable for production environments.
Swift on dedicated nodes: In this case the Proxy service and Storage (account/container/object) services reside on separate nodes, with two proxy nodes and a minimum of three storage nodes.
