File systems unfit as distributed storage backends: lessons from ten years of Ceph evolution – the morning paper

Using shared filesystems for distributed systems is pretty common, and it works fine when it’s small and lightly used. It starts to break in very bad ways at scale.

"Ten years of hard-won lessons packed into just 17 pages (13 if you don’t count the references!) makes this paper extremely good value for your time. It’s also a fabulous example of recognising and challenging implicit assumptions. In this case, the assumption that a distributed storage backend should clearly be layered on top of a local file system. Breaking that assumption allowed Ceph to introduce a new storage backend called 'BlueStore' with much better performance and predictability, and the ability to support the changing storage hardware landscape.
