That's not really the same thing as backing actual Swift services
with data stored in Ceph, that's replacing the user-facing Swift API
with Ceph's attempt to recreate some of the same functionality. For
a lot of people that's "good enough" but note that there are a lot
of things which won't be quite the same (like lack of proper
multi-tenant namespacing for containers, performance limitations
with large container counts, et cetera) but also there's a number of
Swift features that Ceph simply doesn't have.
