Ceph is a storage platform that can be used as object storage, as block storage, and as a file system, typically running on a cluster of commodity servers. With its first major release having been in July 2012, Ceph is certainly not a new product. We do want to highlight it on this Technology Radar as an important building block for private clouds. It is particularly attractive because its RADOS Gateway component can expose the object store through a RESTful interface that is compatible with Amazon S3 and the OpenStack Swift APIs.
