An Object Storage is a collection of objects that coul be shared and secure among a network storage. Using this model, the Data Space is allocated inside the object store instead of a traditional piece of software like a File System.
One of the most important parts of and Object store is the metadata...
At IFCA, the Object Storage interface is implemented through Ceph Rados Gateway, in contrast with the Object Storage Swift service available OpenStack. However, the Ceph Object Storage is "fully" compatible with the Swift and S3 API. Following this line, the data is stored inside the Ceph Storage Cluster that is accesible through the Ceph Object Gateway (rados gw) using HTTP requests or from the Ceph Block Device Client (cinder).
