In UML modeling, deployment relationships specify that a particular node type supports the deployment of an artifact type.
Typically, deployment relationships do not have names.
As the following figure illustrates, a deployment relationship is displayed as a dashed line with an open arrow at one end. The keyword «deployment» appears beside the dashed line.
You can show that an e-commerce application can operate on several kinds of servers with different processor speeds. Each server (represented by a node) runs or uses specific library (.jar) files (represented by artifacts) of the e-commerce system. You can add deployment relationships between each server node and each .jar artifact to indicate which artifacts can run on specific nodes.
