Let us say you have an org created on Edge called myorg with two environments test and prod. You may want to configure a domain name for using your APIs like api.myorg.com for prod environment and test-api.myorg.com for test environment. You do this by creating virtual hosts and adding DNS entries in the router.
When creating a virtual host for these environments you also need to specify a name for it like "default" and "secure" used on the Edge public cloud. When you name the virtual host for the private cloud deployments, it is advisable to have the same name across environments. The benefit would be that you don't need to change the VirtualHost config on ProxyEndpoint when deploying or promoting revisions across test and prod environments.
