DEVICE AND METHOD FOR OPERATION ATOMICITY AND STORAGE REPLICATION OF CLOUD STORAGE BASED COLLABORATIVE MIDDLEWARE

摘要

The present invention relates to an atomic operation of a collaboration middleware based on cloud storage and a storage replication apparatus and method. In the atomic operation and storage replication method of a collaboration middleware based on cloud storage according to an embodiment of the present invention, A first step of performing Storage Primitive Operations (SPO) for processing resources of cloud storage; A second step of a database manager performing metadata primitive operations (MPO) for processing metadata of the resource stored in the database; And if the raw operation of at least one of the storage raw operations and the metadata raw operations is not performed, the cloud manager returns the cloud storage to a state prior to execution of the storage raw operations, And returning the metadata of the resource to a state before the execution of the metadata primitive operations.
