What does your server setup look like — and what's the most painful part of managing it?

 Curious what everyone here is working with. How many servers are you managing, and what breaks down first when the number grows? Is it access management, keeping things consistent across machines, visibility into what's actually running — or something else entirely?                                                                                                                                             Would love to hear what problems brought you here and what you're hoping Fleet solves for you.
