It is a skill much like maintaining a car yourself, or your own lawn/garden.

It’s pretty easy to get started, and there are certain ways of doing things that keep it pretty simple forever, at the cost of some flexibility.

But no matter how you do it, there will be a non-zero amount of work involved indefinitely. Just like you need your cars oil changed, your garden mulched and weeded, or your server patched and cleaned up once in awhile.
