Well, in terms of learning, I‘m still learning, and I‘m already a few years in. In terms of time in front of a screen, it depends on how much automation you throw at your services and builds. It will always come back to questions like: what if an update changes the way the software works? What if something breaks, like a config or a dependency overwrites another. How good do you know the parts of the services for troubleshooting? Do you have a backup? How fast can you rebuild your systems? If you have answers to these questions, you can feel confident in hosting services for yourself and others. If not, you can try but will run into these moments at some point, where you need to fix something fast. And that‘s the moment where you spent your time in front of a screen.
