Spent the first 10 years of my IT career driving towards greater control over the systems we managed, because "the reason the service is down is that someone else (usually a vendor) didn't do their job" was never an excuse. The last 5-10 years I've found myself ceding more and more control to cloud service vendors (like Microsoft). Less work for me ("raise a premium case"). Less stress too ("they're working on it, nothing for us to do"). Now I finding myself hoping I'll be retired before the pendulum swings back again.
