An AEM installation generally consists of at least two environments:
These environments interact to let you make content available on your website so that your visitors can access it.
The author environment provides the mechanisms for creating, updating, and reviewing this content before actually publishing it:
On the author environment, the functionality of AEM is made available through AEM’s authoring user interface. For the publish environment, you design the entire look-and-feel of the interface made available to your users.
The author works in what is known as the author environment. This environment provides an easy to use interface (graphical user interface (GUI or UI)) for creating the content. It requires the author to log on, using an account that is assigned the appropriate access rights.
Your account needs the appropriate access rights to create, edit, or publish content.
Depending on how your instance and your personal access rights are configured you can perform many tasks on your content, including (among others):
Also, there are administrative tasks that help you manage your content:
AEM is also administered from the author environment.
AEM also offers a Sites preview service that lets developers and content authors preview a website’s final experience before it reaches the publish environment and is available publicly.
See Previewing Content for further details.
When ready, your 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.
For more information about publishing and unpublishing pages, see the document Publishing Pages.
To optimize performance for visitors to your website, the Dispatcher implements load balancing and caching.
