Deployment in Architectural Modeling

Deployment 
➤A node is a physical element that exists at run time and represents a computational resource, generally having at least some memory and often processing capability 
  • Used to model the topology of the hardware on which a system executes 
  • Represents a processor or a device on which a components may be deployed 
➤Graphically, a node is represented as a cube

  • Names
  • Nodes and Components
  • Connections
  • Common Modeling Techniques
Names:
  • Every node name is unique which distinguish from it from other nodes
  • It has simple name and path names

Nodes and Components 
  • Components participate in the execution of a system and nodes execute components 
  • Components represent physical packaging where as nodes represent physical deployment of components

Connections:
  • Association relationship is used among nodes 
  • It shows Ethernet connection, serial line, shared bus etc 
  • It also shows an indirect connection like satellite link between distant processors
