congrats, the only attack vector that's left is you
So good! And this is how to do it
Start with a small VPS first, see how far you can take it
Learn about security, and if you have an actual business, get a security/server guy to check your set up so it's safe for production
But slowly learning and building it up to your own virtual server farm with multiple servers is the way to go!
You'll be shocked running 25 servers at $5/mo = $125/mo!
