Object storage, often referred to as object-based storage, is a data storage architecture for handling large amounts of unstructured data. This is data that does not conform to, or cannot be organized easily into, a traditional relational database with rows and columns.
Objects are discrete units of data that are stored in a structurally flat data environment. There are no folders, directories, or complex hierarchies as in a file-based system. Each object is a simple, self-contained repository that includes the data, metadata (descriptive information associated with an object), and a unique identifying ID number (instead of a file name and file path). This information enables an application to locate and access the object. You can aggregate object storage devices into larger storage pools and distribute these storage pools across locations. This allows for unlimited scale, as well as improved data resiliency and disaster recovery.
