In AEM environment, it is common to have both Author and Publish instances, except where the business requirement doesn’t require any publish environment.

Today we will see what is replication, and how it is useful.

Once authors have created content in author servers, and reviewed it, the ultimate goal is to make it available on the website, which is hosted through publish environment.

This process of making the content available to the public by publishing from author to publish instance is called “Publishing / Activation / Replication”.

What is Replication / Activation / Publishing:

General terms for the actions that make your pages/content publicly available on your publish environment. This can be done from either Sites console by authors, or from CRXDE by developers


General terms for the actions that revoke your pages/content from publish environment.

Activation / Deactivation

These are synonymous with publish/un-publish.

Replicate / Replication

Technical terms describing the movement of content from one environment (author/publish) to another (publish/author) such as when publishing content or reverse-replicating user comments.

The replication and reverse-replication agents can be configured at the following url:

The above screen shows three links by default.

Agents on Author:

They are the replication agents that are configured on your author server. Basing on the instance (i.e, whether author or publish), you will be either using “Agents on Author” or “Agents on Publish”.

To configure the replication agents for publish environment, we will use the “Agents on Author”. Content can be replicated to more than one publish server. So we can configure more than one replication agent in this screen.
