Question about using a paid host.

Hi, I've used to own a couple of servers back in the day, but I was using pre-made servers from ragnarok hosts that pretty much spoonfed me everything, all I had to do was edit some scripts to change in game stuff. Now I'm trying to learn more about hosting a server using hosts like AWS, OVH, etc. I'm not sure how much difference it is, just wanted to learn

My questions are:
How does this whole thing work? Do I have to send any specific files to the host for them to host it? I've read a topic mentioning getting an IP from the host and using the IP in the configuration files, does that mean I have to run the servers on my end, while the data are being send through the host's servers? 

You could obviously tell from my questions I'm no computer scientist, hopefully I posted this in the correct section of the forum.

Basically you'll have to do everything, from downloading the files to your host, configuring it (setting up database and editing configure files), setting up the client side. There are some guides here about it.

Oh okay, thank you so much! Back to searching the forum.
