Based on cloud computing and cloud storage, this paper discussed three kinds of typical virtualization technology in cloud computing, that is, storage virtualization based on host or server, storage virtualization based on storage devices, and storage virtualization based on Storage Area Network (SAN). In addition, application value of storage virtualization technology was discussed. What's more, platform architecture model of cloud storage was proposed, and the characteristics of cloud backup were discussed as an example.
