We are. Using Ceph's RADOS Gateway (Hammer, 0.94.11) as the gateway with CloudStack 4.5 (Yes...
;( ).

It is, but our experiences are mainly with 4.5. It still uses a ancient version of the AWS
S3 SDK and that causes most of our troubles.

In general we however see the ACS copies a lot of Objects to the S3 store and downloads them
again afterwards. Not always the best thing. I wouldn't use Amazon S3 directly as that might
cause a lot of data transfer.

Should be running 4.9 within 4 weeks, can report on it a lot better then.
