Self hosting is not always about hosting at home. A private VPS/VDS, co-located server that you own/lease and operate is essentially that. I take self hosting as not turning to big tech for the very same solutions I can spin up myself on a private server.
That being said, self hosting also involves servers at home that run personal services.
My line of work is mostly in business. Getting people to operate their businesses with open source tools on private servers, local, in the country and abroad, as they wish.




It took me 6 deploys to finally understand all the mechanisms. What I like about self-hosting and the open source mantra in general is that every failure is a lesson with field experience. So skills development and acquisition is fairly easy if you push for it and once you get it, its wash, rinse, repeat.
