## Administration Console Overview

The Administration Console is a browser-based tool that features an easy-to-navigate interface. The Application Server consists of one or more domains. A domain is an administrative boundary or context. Each domain has an administration server (also called the Domain Administration Server or DAS) associated with it and consists of zero or more standalone instances and/or clusters. Each cluster has one or more homogeneous server instances. A server instance is a single Java Virtual Machine (JVM) that runs the Application Server on a single physical machine. Server instances (whether standalone or clustered) in a domain can run on different physical hosts.

The DAS provides a central point for managing a Application Server domain. In a domain where there is a single Application Server instance, that server functions as the DAS. The DAS hosts the Administration Console, which is a web application accessible from any supported web browser with network access to the administration server.
