There are lots of entities that are big enough. Given that the cloud stacks change from time to time, you don't reduce your need for engineers and other SMEs -- in some cases you need more.

I would say as someone who supports lots and lots of apps that cloud services are usually financial winners in a SaaS perspective and in a rapid growth scenario. Nobody can deliver Exchange cheaper than Microsoft. My team stood up apps for covid related activity for 20-40% of the cost and more importantly type than services under our organizations control.

That said, for what I would call "base load" scenarios, in many scenarios it's exactly the opposite.
