The vector stencils library "UML deployment diagrams" contains 31 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"A deployment diagram in the Unified Modeling Language models the physical deployment of artifacts on nodes. ...
The nodes appear as boxes, and the artifacts allocated to each node appear as rectangles within the boxes. Nodes may have subnodes, which appear as nested boxes. A single node in a deployment diagram may conceptually represent multiple physical nodes, such as a cluster of database servers.
There are two types of Nodes.
(1) Device Node.
(2) Execution Environment Node." [Deployment diagram. Wikipedia]
The example "Design elements - UML deployment diagrams" is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
