A domain in GlassFish is basically a set of configurations that are used together in a single environment. Usually, you would need a single domain folder and it's safe to use the stock domain1. Inside a domain you can define multiple isntances and even multiple clusters so you don't need to have more than one domain at a time.

More domains are useful when you want to switch between different configurations frequently, or as templates for varioius environments. You could have a development domain, test domain, production domain, each tuned for specific environments.

For example, Payara Server, which is derived from GlassFish, adds additional payaradomain, which is tuned for production, while the default domain1 is tuned for development as it's in GlassFish. Therefore you may easily choose the best default configuration for your needs just by switching the domain when you start the server.

Another usecase would be if you develop 2 or more unrelated applications and you want to keep them separate in the server. Then you would create a separate domain for each of them and run GlassFish with the appropriate domain so that the applications are isolated. The second domain can be configured to a different set of ports so that the servers don't collide.
