!!! Overview[1]
[{$pagename}] (also known as [object-based] storage) is a computer [Data Store|DataStore] architecture that manages [data] as [objects], as opposed to other [store] architectures like [File System] which manage [data] as a file [hierarchy] and [block storage] which manages [data] as [blocks] within sectors and tracks.

Each [{$pagename}] typically includes the [data] itself, a variable amount of [metadata], and a [globally unique identifier|UUID]. 

[{$pagename}] can be implemented at multiple levels, including the [device] level (object storage device), the system level, and the interface level. In each case, [{$pagename}] seeks to enable capabilities not addressed by other storage architectures, like interfaces that can be directly programmable by the application, a namespace that can span multiple instances of physical hardware, and data management functions like [data] replication and data distribution at object-level granularity.

[{$pagename}] provides programmatic interfaces to allow applications to manipulate data. At the base level, this includes [CRUD] functions. 

Some [{$pagename}] implementations go further, supporting additional functionality like object versioning, object replication, and movement of objects between different tiers and types of storage. Most [API] implementations are [REST]-based, allowing the use of many standard [HTTP] calls.

[{$pagename}] is implemented from several vendors like:
* Amplidata
* Bycast
* Cleversafe
* Cloudian
* Nirvanix
* Scality
* DataDirect Networks (WOS)
* Dell EMC Elastic Cloud Storage
* Centera
* Atmos
* HDS (HCP)
* [IBM]
* NetApp (StorageGRID)
* [Red Hat] GlusterFS
* [Amazon] ([AWS Simple Storage Service])
* [Microsoft] ([Microsoft] [Azure])
* [Google] ([Google Cloud Storage])
* Lustre
* [OpenStack] (Swift)
* MogileFS
* Ceph
* OpenIO
