Käyttöönottokaavioita

Käyttöönottokaavioita, known in English as deployment diagrams, are a type of Unified Modeling Language (UML) diagram. They are used to visualize the physical deployment of artifacts on nodes in a system. These diagrams illustrate the hardware and software components of a system and their relationships, showing how software elements are distributed across physical computing resources.

A deployment diagram consists of nodes, which represent physical resources like servers or devices, and artifacts, which are the physical pieces of information that are deployed on nodes, such as executables, libraries, or databases. The relationships between artifacts and nodes, as well as between different nodes themselves, are depicted to show the structure of the deployed system. Communication paths between nodes can also be illustrated to indicate how they interact.

The primary purpose of a deployment diagram is to model the physical architecture of a system. This includes understanding the distribution of software components, identifying potential performance bottlenecks, and planning the deployment strategy. They are particularly useful in distributed systems, embedded systems, and situations where the physical hardware configuration is a significant aspect of the system's design. By providing a clear overview of the physical deployment, these diagrams aid in system analysis, communication among development teams, and documentation of the system's infrastructure.
