One of the primary new features of JBoss Application Server 7 is the ability to manage multiple JBoss Application Server 7 instances from a single control point. A collection of such servers is referred to as the members of a "domain" with a single Domain Controller process acting as the central management control point. All of the JBoss Application Server 7 instances in the domain share a common management policy, with the Domain Controller acting to ensure that each server is configured according to that policy. Domains can span multiple physical (or virtual) machines, with all JBoss Application Server 7 instances on a given host under the control of a special Host Controller process. One Host Controller instance is configured to act as the central Domain Controller. The Host Controller on each host interacts with the Domain Controller to control the lifecycle of the application server instances running on its host and to assist the Domain Controller in managing them.
When you launch a JBoss Application Server 7 managed domain on a host (via the domain.sh or domain.bat launch scripts) your intent is to launch a Host Controller and usually at least one JBoss Application Server 7 instance. On one of the hosts the Host Controller should be configured to act as the Domain Controller
