What to install the server on?

Question

Node.js

I don’t rummage in the backend at all. For the first time in my life, I wrote a server in Node JS that performs the functions I need. It works fine for me locally. Now I have a need for it to work 24/7, so I need to install it on something. And for what? What is used for this?
I know that there are some dediks, VDS, VPS. I'm really confused and don't understand what I need. From what I tried to understand: a dedicated computer is something like a dedicated computer that is running 24/7 and which I can remotely control (well, that is, move the mouse directly on the desktop, in short, the OS is full-fledged). VPS, as I understand it, makes it possible to work only with the file system and run the server itself, nothing more.
In theory, the best option is Dedik, right? Well, that is, I can directly upload all the files of my server to it, install Node JS on it and run it through npm start, open the port and then I can make requests to it. Isn't it true?

PS Sorry for the mess of terms. It's just too complicated, I get confused in all these VPS, VDS, Dedicated servers...

Answer 1

"Dedik" is a dedicated server, completely your iron server in someone's data center.
Yes, you can run Windows on it without any hesitation and crawl with the mouse. But it stands like a wing from an airplane, and you should not be interested at all.
For a pet server that doesn't need to handle an influx of users or handle heavy tasks, the cheapest VPS for 55 rubles/month will most likely be more than enough.
BUT! No mice on the desktop. Linux, command line, all the freedom of administration...
