=====================
Ceph Object Gateway
=====================
:term:`Ceph Object Gateway` is an object storage interface built on top of
``librados``. It provides a RESTful gateway between applications and Ceph
Storage Clusters. :term:`Ceph Object Storage` supports two interfaces:
#. **S3-compatible:** Provides object storage functionality with an interface
that is compatible with a large subset of the Amazon S3 RESTful API.
#. **Swift-compatible:** Provides object storage functionality with an interface
that is compatible with a large subset of the OpenStack Swift API.
Ceph Object Storage uses the Ceph Object Gateway daemon (``radosgw``), an HTTP
server designed for interacting with a Ceph Storage Cluster. The Ceph Object
Gateway provides interfaces that are compatible with both Amazon S3 and
OpenStack Swift, and it has its own user management. Ceph Object Gateway can
store data in the same Ceph Storage Cluster in which data from Ceph File System
clients and Ceph Block Device clients is stored. The S3 API and the Swift API
share a common namespace, which makes it possible to write data to a Ceph
Storage Cluster with one API and then retrieve that data with the other API.
