You can use DNS (public or private) or host file entries that reference the private IP of the node if you choose to use hostname. > Does anyone have any best practices around vm.args -name in EC2 environments? We haven't outlined any best practices ourselves, but I tend to believe using a hostname that you can change the IP for via DNS or a hosts file is a more flexible way of approaching the problem.
