Deployment Diagrams

Deployment Diagrams

• A deployment diagram illustrates the physical deployment of the system into a production (or test) environment.
• A deployment diagram shows all of the nodes on the network, the connections between them, and the processes that will run on each one.
• It shows where components will be located, on what servers, machines or hardware.
• It may illustrate network links, LAN bandwidth etc.
• Depicts physical relationships among software and hardware in a delivered system.
• Explains how a system interacts with the external environment

Deployment diagrams consist of : 

• Processors
• Devices
• Connections

Processor

• Any machine that has processing power
• The servers, workstations, and other machines with processors are included in this category
• Depicted as three-dimensional boxes

Device

• Machines or pieces of hardware without processing power
• Devices include items such as dumb terminals, printers and scanners
• Also depicted as three-dimensional boxes

Connection

• Physical link between two processors, two devices or a processor and a device
• Most commonly, connections represent the physical network connections between the nodes on your network
• A connection can also be an Internet link between two nodes
• Depicted as lines

Example

Component and deployment diagrams may be combined with components displayed within the processor boxes.
