A deployment diagram shows the physical implementation and architecture of a system. It includes nodes which represent hardware or software elements, artifacts which are products of development like files, and connections which depict communication between nodes. Node types are devices and execution environments. Artifacts are denoted by boxes with the <<artifact>> stereotype. Connectors define the physical links between nodes, sometimes using stereotypes. An example deployment diagram displays a web server, database server, and user machine. Deployment diagrams visualize hardware topology, model physical elements and connections between them, and describe processing nodes at runtime.

2. Deployment Diagram
 Deployment Diagram Deployment Diagram is a
very simple diagram which is used to represent
the physical implementation of a system or a
physical architecture of a hardware. Deployment
diagram presents a static view of the system.

3. Elements of Deployment Diagram
There are only three elements for a deployment
diagram. They are :
 Node
 Artifact
 Connection

4. Node
 A Node represents hardware or software element of a
system. Node is shown as a three dimensional box.
There are two types of nodes in a deployment
diagram:
 Device nodes :-Device nodes are computing resources
with processing capabilities and the ability to execute
programs. Some examples of device nodes include
PCs, laptops, and mobile phones.
 Execution Environment Nodes:- An execution
environment node, or EEN, is any computer system
that resides within a device node. It could be an
operating system, a JVM.

5. Artifacts
 Artifacts are product of a software development
process. They can range from models, files to
documents. Artifacts are denoted by a rectangular
box with <<artifact>> stereotype and a file icon in
the box.

6. Connectors
 Connectors are lines drawn between nodes, they
are used as communication medium between
nodes. Name of the physical connection can be
represented using stereotypes. For Example
<<Ethernet>>, <<message bus>> etc.

7. Deployment Diagram Example
 There is a web server, a database server, and the machine where the user
views the website.

8. Purpose of Deployment Diagrams
The purpose of deployment diagrams can be
described as −
 Visualize the hardware topology of a system.
 They model physical hardware elements and the
communication paths between them
 Describe the runtime processing nodes.
