How many businesses can’t afford to suffer any downtime though?
But I’ve led enough cloud implementations where I discuss the cost and complexity between - multi-AZ (it’s almost free so why not), multi region , and theoretically multi cloud (never came up in my experience) and then cold, warm and hot standby, RTO and RPO, etc
And for the most part, most businesses are fine with just multi-AZ as long as their data can survive catastrophe.
