Realms
Realms - or server groups as you might call them, share some data between eachother.
Data between realms will not be copied over at any time, so choose your realm/server wisely.
The DEV/Apollo server recieves live codebase updates, and is later pushed out to the other servers manually.
As in - dev usually has more features and instant bug fixes, but can be unstable and chaotic.
