10. Managed Cloud storage Amazon EMC Google storage for developers IBM smart Business storage cloud Nirvanix Rackspace

12. Cloud Data Management Interface (CDMI) Specifies an API that a server must implement so that remote clients can store, retrieve, and manage data via web services (http calls)

15. A client of both interfaces would perform the following operations as an example: The Client creates a CDMI Container through the CDMI interface and exports it as an OCCI export type. The CDMI Container ObjectID is returned as a result. The Client then creates a Virtual Machine through the OCCI interface and attaches a storage volume of type CDMI using the ObjectID. The OCCI Virtual Machine ID is returned as a result. The Client then updates the CDMI Container object export information with the OCCI Virtual Machine ID to allow the Virtual Machine access to the container. The Client then starts the Virtual Machine through the OCCI interface.
