Concept of Authoring (and Publishing)
AEM provides you with two environments:
These interact to enable you to make content available on your website - so that your visitors can read it.
The author environment provides the mechanisms for creating, updating and reviewing this content before actually publishing it:
1. An author creates and reviews the content (this can be of several types; for example, pages, assets, publications, etc)
2. Which will, at some point, be published to your website.
The author works in what is known as the author environment . This provides an easy to use interface (graphical user interface (GUI or UI)) for creating the content. It is usually located behind a company's firewall that provides full protection and requires the author to login, using an account that has been assigned the appropriate access rights.
When ready, the AEM site's content is published to the publish environment . Here the website's pages are made available to the intended audience in accordance with the look-and-feel of the designed interface.
Usually, the publish environment is located inside the demilitarized zone; in other words, available to the internet, but no longer under the full protection of the internal network.
