- * Native API
- * Via a RESTful interface that can handle native Amazon S3 and Swift API calls
- * As a thinly provisioned block device
- * Mount it as a POSIX-compliant file system via CephFS (although this is a bit rough for production environments just yet)
Josh Durgin has actually done some really interesting work in using the block device (RBD) to back Cinder which you can read a bit about here.
The cool part about Ceph is it was designed to be massively scalable (petabytes and beyond) and extremely fault tolerant / HA / etc. DreamHost actually just built out a huge production deployment of Ceph and OpenStack for their new DreamCompute / DreamObjects offering. If you have questions feel free to hit up the #Ceph irc channel at irc.oftc.net or poke me via email (my UN at inktank.com) and I'll see if I can't find the right person to help.
OpenStack really has some awesome potential, and we're excited about poking at it more with our semi-sharp Ceph-stick. Good luck.
