I think you are missing the point. When I state my Exchange server is more reliable than Exchange Online, I don't think I'm a better engineer. I recognize Microsoft has harder problems to solve than I do. I think building overengineered, oversized SaaS environments is introducing extreme risk. It's an inherent flaw of the current approach.
Smaller is, in fact, better, because it's easier to operate reliably.
