I used to run a lot at home. But i realized that "support" stops when i would die.
My family, who is a- technical, would have not even have a clue on where would be what (since they freak already out if an icon on their phone is move 1 millimeter). So from that nonfunctional requirement for my own home solutions, I decided that self-hosting would not be the best choice, since it would be too dependent on me.
My family's knowledge stops somewhere at the concept of that pressing the B makes a word bold in Microsoft Word. Trying to explain how to run a script on a certain OS via a certain connection would be abracadabra.
The only thing i can imagine is if there would be some kind of paid service that would mirror your own home solutions and provide support for the long run if you fall away and which offers, when there would be again someone more technical to again transfer it to a home environment. (they would take care of new versions, bugfixes, change requests, databackups and so on).
Something like that, but that does not exist (well... as far I know).
So therefore, i try to host every solution at the places which are the simplest to understand and document what needs to happen if I would fall away. I also try to minimize the number of services. So I use office365 and onenote to document everything. (This used to be on my own hosted wiki).
Based on the nonfunctional requirement of maintainability.
I think there is however a need for a service that offers something like the above, to provide long term support for selfhosted environments taking into account all kinds of standards. That would possibly enable the self-hosted direction again.
