These are the typical environments that most people would use but you can define your own if you want. You can have as many Automation node environments as you want, or you could directly deploy to Automation Production, it's to you. The idea of having an Automation Development environment is that you can test your project in the Automation node which is supposed to be hands off developers and run projects in unattented mode. So it gives Developers a chance to test their flows in the Automation node before moving them to Test.
