Hey there Sam_78

you can use the same domain name on different servers -  there are several ways to accomplish this and you do need to get with your hosting company to see which one will work best for you.

Note:  you need to decide on how you want to keep your data in sync -  if one server is "down" or out of rotation the next one will take the db changes,  when the first one is up,  you need that info to be sync to the transactions of the one that got the info
