File systems unfit as distributed storage back ends: 10 years of Ceph

I found the story of how Backblaze stores things "on top of", versus "in" filesystems similarly interesting. https://www.backblaze.com/blog/vault-cloud-storage-architect...

It seems like they could go one further and eliminate the ext4 underneath.

Hi! This could have been submitted as an HTTPS link.

I assume if the owner of the site wanted to redirect all http->https traffic they would do so.

Doing that doesn't actually solve the problem though. A MITM attacker still gets to read and modify all that content.

It’s true. Why, just as I was loading the page, someone replaced all instances of “filesystem” with “butt”! The nerve!

But ceph has the bluestore backend that doesn't go through the file system.

Ceph is awesome, even years ago it was a great Technology. We from croit.io do provide a free software to manage Ceph with ease.
