People that dont like the cloud are generally engineers who were left behind by the paradigm shift. They want development to go back to what they spent a decade learning. And so they complain about complexity or out of control cost. The truth is, they arent effective engineers with the cloud because they havent learned it in depth. It is clearly 100x better than on premise, and the boom in tech is partially from productivity gains from cloud. Infrastructure as Code is a major technological improvement.
