A deployment manager is a server that manages operations for a logical group, or cell, of other servers. The deployment manager is the central location for administering the servers and clusters.
You use the administrative console of the deployment manager to manage the servers and clusters in the cell. This includes configuring servers and clusters, adding servers to clusters, starting and stopping servers and clusters, and deploying mediation modules to them.
Although the deployment manager is a type of server, you cannot deploy modules to the deployment manager itself.
