Key elements of a Deployment Diagram
1. Nodes
These represent the physical hardware entities where software components are deployed, such as servers, workstations, routers, etc.
2. Components
Represent software modules or artifacts that are deployed onto nodes, including executable files, libraries, databases, and configuration files.
3. Artifacts
Physical files deployed onto nodes, embodying the actual implementation of software components, such as executables, scripts, databases, etc.
4. Dependencies
Reflect relationships or connections between nodes and components, indicating communication paths, deployment constraints, or other dependencies.
5. Associations
Show relationships between nodes and components, signifying that a component is deployed on a particular node, thus mapping software components to physical nodes.
6. Deployment Specification
Describes the configuration and properties of nodes and components, encompassing hardware specifications, software configurations, communication protocols, etc.
7. Communication Paths
Represent channels or connections facilitating communication between nodes and components, including network connections, communication protocols, etc.
Deployment Diagram in Unified Modeling Language(UML)
A Deployment Diagram in software engineering is a type of Structural UML Diagram that shows the physical deployment of software components on hardware nodes. It illustrates the mapping of software components onto the physical resources of a system, such as servers, processors, storage devices, and network infrastructure.
