What is the difference between developing a local server using (vagrant virtual box) and a real one?

Question

virtual box

Good
afternoon Tell me what is the difference between setting up and maintaining a server on a hosting site from a local server?
I am interested in working moments such as installing modules / changing the configuration / starting, etc.
I have experience with Vagrant and Virtual box and more or less skills with back-end technologies such as laravel nodejs nginx apache can I support the server myself or do I need someone else for this then?
(the server will be on a VPS)
I would be very grateful for a link to a step-by-step manual for starting a server for high-load services
Thank you
