There have been two circumstances where we’ve seriously thought about it, but as of yet haven’t changed:
1) Under some circumstances we might want to give very stringent uptime guarantees for some systems, and I do not trust providers to have zero global (cross AZ) outages. Having a hot standby or even load balancing across clouds could be tempting.
2) One cloud provider is very keen to get into our sector and has made extremely generous overtures which we’d be silly to completely ignore.
As I say, not something we’ve followed through as yet but both are serious considerations.
