Ark ps4 server hire second ps4?

Good day together I would have a question and that's why if you want to host a server on the Ps4 then you need a second ps4 but how does it look if you would rent a server at nitrado, etc? Would it be necessary to rent a second ps4?

If you rent at Nitrado, of course, you need no 2nd PS4, because the server is running so then at Nitrado…
