A Construction Method and Data Migration Strategy for Hybrid Cloud Storage

With more and more enterprises constructed their own private cloud storage platforms, certain limitations and challenges come for small and medium enterprises. So hybrid cloud storage is imperative with public cloud as a complement. In this paper, we propose a fast and efficient method to build a hybrid cloud storage framework: base on open source software OpenStack Swift to build the private cloud storage, use Baidu Object Storage as the public cloud provider, and do a second development of Cyberduck as the cloud storage client. This framework can realize the seamless integration of private and public cloud. To tackle the data migration problem in hybrid cloud storage, we present a part-migration-part-retention self-adaptive periodic migration strategy, and the specific implementation of migration process is given. The strategy not only improve the utilization rate of local cloud storage, but also make reasonable use of public cloud storage.
