In UML modeling, you deploy artifacts on nodes to indicate
that the node supports the deployment of instances of these artifacts
when the system runs.
A diagram must be open in the diagram editor and
it must contain at least one node and one artifact. The Deploy compartment
of the node must also be visible.
To specify the deployment of an artifact on a node, in
the diagram editor, click an artifact and drag it over the Deploy compartment
of the node.
As the following figure illustrates, the artifact is
displayed in the Deploy compartment and a deploy relationship connects
the node to the artifact.

Note: You can also deploy artifact instances on node
instances.
