The customer-facing cluster is also referred to as the production cluster. The modules that make up your customer-facing Web applications run here.

The users associated with applications running on this cluster are external users (your Web site customers).

All instances in this cluster run the same modules. These include ABTest.runtime and Outreach.runtime as well as the modules for outward facing applications.

If Self Service is running on this cluster, it receives deployments from the asset management cluster and the agent-facing cluster.

The customer-facing cluster requires an external scenario editor server. You must designate one instance in the cluster as the global scenario editor server. The instance you designate is usually dedicated to that task; the load manager does not send it Web traffic in production. Refer to the ATG Personalization Programming Guide for more information. See also Relationships between Clusters, Users, and Scenario Servers in this guide.

Another instance in this cluster is usually dedicated to running lock managers. The load manager does not send it Web requests.
