There is a whole ecosystem that pushes cloud to ignorant/fresh graduates/developers. Just take a look at the sponsors for all the most popular frameworks. When your system is super complex and depends on the cloud they make more money. Just look at the PHP ecosystem, Laravel needs 4 times the servers to server something that a pure PHP system would need. Most projects don't need the cloud. Only around 10% of projects actually need what the cloud provides. But they were able to brainwash a whole generation of developers/managers to think that they do. And so it goes.
