Why Ceph Upstream?
Ceph Upstream is the technological foundation of the Ceph project.
This is where new features, architectural decisions, and bug fixes are created – openly, transparently, and driven by the community.

Ceph Upstream is not a finished product, but a powerful platform.
That is exactly what makes it strong.
