That's a time vs. outsourcing trade-off. When everything is working, it's invisible and great, but if something breaks, and if you're in the middle of the something, you either have to postpone it, or stop everything and fix the problem to be able to continue your life unaffected.

I'm into self-hosting, and host some of my services myself, but get some services too, because I have limited time and don't want to stop drop and roll when something breaks.
