I think xsevensinzx hit it on the head - cloud services have automated the request process for asking for more hardware or services - that process alone in some organisations is either unavailable to many or takes a ridiculous amount of time and energy.

It very much standardises the platform and processes as well for employees between companies - no more learning new admin processes every time you move to a new company or knowing "the" person to talk to about all the undocumented configurations that take a few months or years to get to grips with.
