I'm considering renting a Atlas server before I do though I'm curious how the clusters work exactly. In regards how its all setup in relation to the full map. Say I rented 4 servers. Would I be able to seamlessly explore the whole map as long as my players are in no more then 4 different zones at the same time? Or do I need to specify how the servers are linked up and which parts of the map they belong to? If I do need to specify how easily can I switch it out as my players wish to explore more and more parts of the map?
