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.
