This talk is very intersting and many threads are very valid here is my stand:
In cloud, DBA do not know how their data is taken care? who do have access to their data? If data/backup is not available for the recovery who is held responsible? As first sight people think DBA failed; finger will point to DBA first. Also there are lots of limitations of Azure. Personally I prefer to have non-cloud environment.
