OPPORTUNISTIC MIGRATION OF DATA BETWEEN CLOUD STORAGE PROVIDER SYSTEMS

摘要

A protocol-agnostic proxy can be used between a cloud client and multiple networked data storage servers as might be operated by cloud service providers. The proxy can, transparent to a requesting client, opportunistically migrate data stored in a first networked data storage server to a second networked data storage server. This can be done as specific data is requested by the client. Data objects can be transparently, to the client, migrated to a second networked data storage server. The complexity of data object retrieval can be opaque to the requesting client. In addition to migrating to a second networked data storage server, the proxy might handle migration to a third and additional servers. The protocols used between various networked data storage services might vary from provider to provider, and even within services of one provider. In any case, the proxy can present a consistent view of data to clients.
