Your reasoning is faulty and very probably self-serving. More and more companies can and will outsource their infrastructure. IT guys hate this because it threatens their "paychecks."

The optimal amount of cloud services for an established company like FedEx is 100%, not merely with a "disaster recovery plan" but with live, 99.99% redundancy by which I mean two almost exact systems running nearly simultaneously (within a second or two of one another) on two completely different networks.

FedEx enjoys almost all of its competitive advantage from its physical network. IT is not core to its business.

Here's the problem... almost no company actually does disaster recovery and "parallel redundancy" properly because most C-level executives only pay lip service to it.

Therefore, the whole notion that disaster recovery and "parallel redundancy" don't work is predicated on the false notion that companies actually have proper disaster recovery and "parallel redundancy" in the first place.

It is surely true that I have a cognitive bias in the direction you say, and that many companies operate at lower levels of informatics infrastructure reliability than Azure.
