Canonical Promotes Ceph Big Data Storage System…For Red Hat?

Canonical, on its official blog, is promoting the latest release of the Ceph distributed storage system, titled Cuttlefish. Why is that noteworthy? Because the post doesn’t mention Canonical’s Linux distribution (Ubuntu) at all, and instead focuses in large part on what Ceph is doing for Red Hat. Is Ceph that important to the open-source and Big Data ecosystems that it can bring competitors so selflessly together like this?
