Think of a farm of small data center pods with cloud apps. When failure in a pod exceed useful threshold, apps are migrated out to other pods and the pod is retrieved, serviced and returned to its place.

A custom made barge with dynamic positioning gear and a grabbing/coupling system to detach the pod from the subsea grid, lift it, and then re-attach it would make the servicing relatively efficient.

I could see the roundtrip time for a full hardware replacement of a pod being under an hour, conceivably under 10-15 minutes.
