Object Storage Protocol

A RESTful protocol-based interface that is used to access storage in the form of objects.
Traditional network attached protocols (NAS) provide support for POSIX semantics. Supporting POSIX makes the NAS protocols quite complex to both understand and implement. In comparison, the object protocol provides a RESTful interface (simple get and put operations) where typically one does not update an object. Instead, every update usually leads towards the creation of a new object. Object storage protocols do not adhere to POSIX semantics. Key-value interface is a specific form of object protocol where the value corresponds to an object. The underlying architecture for implementing a storage system that supports small objects (few kilobytes) is fundamentally very different than a storage system that has been designed for supporting large (mega or gigabytes) objects. Typically, a storage system that...
