Is Ceph Production-Quality?
===========================

Ceph's object store is production ready. Large-scale storage systems (i.e.,
petabytes of data) use Ceph's block devices and Ceph's RESTful object store
supporting APIs compatible with Amazon's S3 and OpenStack's Swift. `Inktank`_
provides commercial support for the Ceph object store, block devices, and 
RESTful interfaces.

The CephFS POSIX-compliant filesystem is functionally-complete and has
been evaluated by a large community of users, but is still undergoing
methodical QA testing. Once Ceph's filesystem passes QA muster, `Inktank`_ 
will provide commercial support for CephFS in production systems.
