Manage subdomains

A subdomain is the part of your URL that appears before your domain name. For example, www is the subdomain of www.amazon.com and aws is the subdomain of aws.amazon.com. If you already have a production website, you might want to only connect a subdomain. Subdomains can also be multilevel, for example beta.alpha.example.com has the multilevel subdomain beta.alpha.
