I'm more or the less the sole decider for all tech decisions in my org (I don't have full budget authority, but I tell the budget holders what things cost). I'm 100% on board with cloud and even going further up the value chain to PaaS and SaaS. Cloud is expensive, but predictable. DevOps is very expensive and unpredictable. I can't even keep staff retained these days. Having a fixed dollar cost, even if it's high, saves not only the operations cost, but also the accounting cost and recruiting cost. And not just cost, but risk! Managed services are generally lower risk, and even if they aren't you can buy some indemnity that they'll cover some of the cost of failures.
