Deployment Diagrams
Deployment diagrams are a type of structural diagram in the Unified Modeling Language (UML) used to model the physical deployment of software components on hardware nodes. They illustrate how software artifacts, such as executables or libraries, are deployed onto hardware infrastructure like servers, devices, or network components, showing the runtime configuration and relationships between hardware and software elements.
Developers should learn deployment diagrams when designing, documenting, or communicating the architecture of distributed systems, cloud-based applications, or embedded systems to ensure clarity in deployment strategies. They are particularly useful in scenarios involving microservices, containerized applications, or IoT setups, as they help visualize scalability, performance bottlenecks, and hardware dependencies, aiding in planning and troubleshooting deployments.
