The customer facing cluster includes customer facing applications available through Web sites, including the following:

These application users are external users.

If this cluster runs ATG Self Service, it receives deployments from the management cluster and from the agent facing cluster.

Internal users with the appropriate roles can use the ATG Business Control Center to manage application users on the agent facing cluster or the management cluster.

All instances in the cluster run the same modules (including ABTest.runtime and Outreach.runtime, as well as the modules for outward facing applications).

The customer facing cluster requires an external scenario editor server. You must designate one instance in the cluster as the scenario editor server; it will be a global scenario editor server. (Multiple instances can be global scenario servers.) The instance you designate as the scenario editor server is usually dedicated to that task; the load manager does not send it Web traffic in production.

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

For details about setting up and running applications, refer to the documentation for each application. For a list of applications and their associated documentation, see About the Applications.
