Ceph is growing rapidly. As firms deploy Ceph, the technical terms such as "RADOS", "RBD," "RGW" and so forth require corresponding marketing terms that explain what each component does. The terms in this glossary are intended to complement the existing technical terminology.
Sometimes more than one term applies to a definition. Generally, the first term reflects a term consistent with Ceph's marketing, and secondary terms reflect either technical terms or legacy ways of referring to Ceph systems.
