In my experience running AWS etc. is something that takes at least one dev who is a subject matter expert, so it doesn't seem like it would be at all problematic to have the same thing for bare metal - a dev who is the SME on the bare metal. Also if you have everything ready to push to a cloud provider in the case of the server going down, someone like Vercel or Netlify (easier to maintain than AWS in my experience) then I guess you are pretty setup.
