We use O365 for years. It is still a software you install on local Windows machines (almost nobody uses the browser version). Aside from billing very little has changed. Cloud made IT a bit easier, but it is still the old work. Since we are lacking IT personal, devs have to support IT (2 IT people for 300 employees, we have difficulties hiring IT staff because most of the good ones have build a their own business by now). But since devs run in a completely different environment in their own subnet, devs can only do so much to support corporate IT. We are delegated to fix old certificates and stuff like this.
