Yes, well.. When entering the server in Guest mode, you don’t need an account, you are completely anonymous, except for the IP address, the network you come from. With Visitors mode, you log in to the Cloud Server with your system account, so the Cloud Server knows who you are and will also pass over this information, but without you having to make a new login on the target node. This is useful because, with Visitor logins, the user doesn’t need to have a system account on the node (and indeed they login to the node as a guest), but you actually consider the user as a user coming with a system login since the user actually logged in to the Cloud Server.
