DEDICATED SERVER GUIDE engine 4.14+

EniGmaa- I’m trying to make multiple dedicated servers in order to have individual maps that players can visit without trying to make a massive world (say, loaded when a player clicks open a door). I intend to shuffle player/game data between them with VaRest/Django/MariaDB/a RESTful interface. Do I need to make an individual UE4 project for each of these dedicated servers (which are essentially only different maps)? If so, do I do that and simply ignore all of the client.exe’s that I will be building for each map/server? What’s the best way to handle the enterprise of building, say, a dozen dedicated servers?
