I'm looking to for a technology that is similar to Amazon RDS, where the engine (ie: WS management, setting up, operating, HA, backups, point in time recovery, scale, etc.) can be deployed in your own data center.
Does anything like this exist?
I don't think that exists. I wouldn't know if its possible either, given that I don't know how the RDS nodes are configured for Amazone. If I were you, I would email the only publicly available person that might know: Jeff at his blog and ask him.
