Ceph

Ceph is an open source, distributed storage platform that provides unified object, block, and file storage on commodity hardware with no single point of failure. The Ceph Manager (ceph-mgr) ships with a RESTful API that exposes the same operations available in the Ceph Dashboard for managing pools, OSDs, hosts, monitors, RGW, RBD, CephFS, and cluster configuration. The API is OpenAPI 3.0 compliant and authenticates via JWT bearer tokens.

Ceph publishes 6 APIs on the APIs.io network, including Auth API, Cluster API, Configuration API, and 3 more. Tagged areas include Storage, Distributed Storage, Object Storage, Block Storage, and File Storage.

Ceph’s developer surface includes authentication, documentation, engineering blog, and 8 more developer resources.
