There are different use cases. It’s possible that the company do not have all that infrastructure at all. I also don’t see the importance of ‘knowledge to run things on premise’ for most people. Technologies change very fast and if I can pay a reliable provider with a fixed price for the years that I intend to use it, why do I have to know how to use it? If I can hire a gardener to take care of things for a reasonable price, I don’t care if I have any knowledge.
