@Antibiotic A vps (virtual private server) is just an instance you run on the internet somewhere.
Its just a vm, so a full OS that you can really pretty much do anything you want on, just like some vm or server you would setup locally but its hosted somewhere on the internet.
If your looking for a lowcost vps, check out https://lowendbox.com they have all sorts of links to deals.
I show one on there currently at racknerd for like $10 a year.

I use to have bunch of different ones in different locations, west cost, east cost, Chicago, EU (NL) - but I trimmed back and currently only one I have active is with https://buyvm.net/ which is 2$ a month currently.. Price has gone up over the years ;) I do have another server currently in NL.. But its not really a lowend box, and is more like $10 month vs a year.
The one I have currently still have, I first got back in 2016, it was $15 a year then. Now its 24.. not really bad price increases, since over the years they have increased what you got for the money.. I might have to spin up one of these 10 a year guys to just kick the ties on it. Might switch over and save myself $15 a year ;) hehehe
If I needed one in a specific location for something I was testing, the great things about these is you can have them spun up and active normally in a few minutes.
