UML Deployment Diagram

Deployment Diagram shows configuration of hardware and software in a distributed system. Deployment Diagram serves to model the hardware used in system implementations, the components deployed on the hardware, and the associations between those components. The elements used in deployment diagrams are nodes (shown as a cube), components (shown as a rectangular box, with two rectangles protruding from the left side) and associations.
An instance can be distinguished from a node by the fact that its name is underlined and has a colon before its base node type. An instance may or may not have a name before the colon. The following diagram shows a named instance of a computer. A connection depicts the communication path used by the hardware to communicate and usually indicates a method such as TCP/IP.
The combination of a deployment and component diagram (shown Figure uml.11) gives as result a general perspective of the whole integration of the system:

Figure uml.11 an example of a Deployment Diagram

A deployment diagram models the run-time architecture of a system. It shows the configuration of the hardware elements (nodes) and shows how software elements and artifacts are mapped onto those nodes. A node usually represents a piece of hardware in the system. A node instance can be shown on a diagram. In the context of a deployment diagram, an association represents a communication path between nodes.
