1.	What is the distinction between the Author environment and the Publish environment?
Answer» AEM is normally RUNNING in two different instances in a production environment. The author instance is one, and the publish instance is ANOTHER. These two instances are typically kept in SEPARATE locations. You'll enter and administer content for your website in the author instance. This is also where you are going to manage your website. Typically, the author's environment is kept behind a firewall. You'll make your content available to your selected audience in the publish instance. In most cases, the PUBLISHING environment is preserved in a DEMILITARIZED Zone (DMZ).
