摘要
The present invention relates to a device and method for an atomic operation and storage replication of collaborative middleware based on a cloud storage. According to an embodiment of the present invention, the method includes: a first step for conducting storage primitive operations (SPOs) wherein a cloud manager processes the resource of a cloud storage; a second step for conducting metadata primitive operations (MPOs) wherein a database manager processes metadata of the resource stored in a database; and a third step wherein the cloud manager resets the cloud storage to a condition prior to the execution of the SPOs, while the database manager resets the metadata of the resources to a condition prior to the execution of the MPOs, if at least any one of SPO or MPO has not been executed.
