Abstract
Embodiments of the present disclosure provide a method and an apparatus for data movement among distributed data centers in a peer network. The method comprises: reducing an amount of data to be moved by pre-processing the data; generating a torrent file for the data; distributing the torrent file to a peer data center, and in response to receiving a data request from the peer data center, transmitting a segment of the data to the peer data center. Compared with the prior art, the embodiments of the present disclosure can realize reliable and fast data movement among distributed data centers over an unreliable and low-bandwidth network, can support an adaptive network topology among distributed data centers without complex pre-configuration or cumbersome runtime coordination, can support different types of data storage, and facilitates coordinated cloud computing and data aggregation among distributed data centers.
