[This section describes one or more physical network (hardware) configurations on which the software is deployed and run. It is a view of the Deployment Model. At a minimum for each configuration it should indicate the physical nodes (computers, CPUs) that execute the software, and their interconnections (bus, LAN, point-to-point, and so on). Also include a mapping of the processes of the Process View onto the physical nodes. This view is OPTIONAL. Use this view only if the system is distributed across more than one node. Even in these cases, only use the deployment view where the distribution has architectural implications. For example, in cases where there is a single server and many clients, a deployment view only needed to delineate the responsibilities of the server and the clients as a class of nodes; there is no need to show every client node if they all have the same capabilities]
