The deployment manager is the central administration point of a cell that consists
of multiple nodes and node groups in a distributed server configuration. See
Figure 3-5 on page 60. The deployment manager uses the node agent to
manage the applications servers within one node.
A deployment manager provides management capability for multiple federated
nodes and can manage nodes that span multiple systems and platforms. A node
can only be managed by a single deployment manager and must be federated to
the cell of that deployment manager.
The configuration and application files for all nodes in the cell are centralized into
a master configuration repository. This centralized repository is managed by the
deployment manager and synchronized with local copies that are held on each of
the nodes. See Figure 3-7.
