I agree, many always start with the premise "hosting is hard", but maybe this was true 20 years ago, now hosting providers let you spin-up a server in a few clicks, have monitoring, alerts, automatic updates and more. The good part is that for 99.99% of the time, once you set-up a server it could keep on running without issues for many years.

I am not a sys-admin but I have used multiple hosting providers (shared, VPS, dedicated) and so far I never had a single server fail or suddenly stop working.
