Honestly I think the best path is hybrid with the cloud as DR and sudden load scaling.
Metal with data streamed to cloud and cloud as hot backup is something some people already do.
If the metal dies in a catastrophic way (multiple nodes at once and loss of quorum, catastrophic DC outage, etc.) you spin it up in AWS.
