A cloud is great.
As ONE item of redundancy.
You could spread across several different clouds, across in-house and cloud, across in-house, externally-hosted and cloud. But a particular cloud is ONE point of potential failure.
Anyone who thinks otherwise ends up with problems like this.
Anyone with a brain, in such an instance, would go "Okay, time to failover to our secondary site which has NOTHING in common with the primary... not a company name, not a cable, not a service, not a switch".
