All other instances of the EAC serve as Agents. The Agents instruct their host machines to do the actual work of a Guided Search implementation, such as processing data with a Forge component, or coordinating the workings of multiple MDEX Engines with an Aggregated MDEX Engine component.

Each Agent also contains a small repository for its own use. The EAC Central Server communicates with its Agents through an internal Web service interface. You do not communicate directly with the Agents—all command, control, and monitoring functions are sent through the EAC Central Server.
