object storage

An approach to storing data where the data is accessed by unique identifiers and not by a user-defined hierarchy of directories and files. Each object has both data (for example, a picture) and metadata (for example, the date the picture was taken).

Object storage operations act on entire objects as opposed to reading and writing bytes as is commonly done with files, and are provided via APIs or HTTP instead of NAS (CIFS/NFS) or block protocols (iSCSI/ FC/FCOE).
