Identify gaps, pinpoint inefficiencies, and mitigate risk in your workflows. Lucidchart is a collaborative workspace that brings remote teams together in real time. The Unified Modeling Language UML is the standard language that many software engineers and business professionals use to create a broad overview for complex systems. A deployment diagram is one type of diagram created with this language.
Along with our UML diagramming tool , use this guide to learn more about deployment diagrams. Do you want to create your own UML diagram? Try Lucidchart. It's fast, easy, and totally free. In the context of the Unified Modeling Language UML , a deployment diagram falls under the structural diagramming family because it describes an aspect of the system itself. In this case, the deployment diagram describes the physical deployment of information generated by the software program on hardware components.
The information that the software generates is called an artifact. This shouldn't be confused with the use of the term in other modeling approaches like BPMN. Deployment diagrams are made up of several UML shapes. The three-dimensional boxes, known as nodes, represent the basic software or hardware elements, or nodes, in the system.
Lines from node to node indicate relationships, and the smaller shapes contained within the boxes represent the software artifacts that are deployed. Use Lucidchart's UML diagram tool to construct deployment diagrams. Before you begin diagramming, ask yourself these questions:. Have you identified the scope of your system?
For example, you should know whether you are diagramming a single application or the deployment to a whole network of computers. What are the limitations of your physical hardware?
What legacy systems will you need to interact with? Make sure that you know the operating software and protocols you will be working with and what monitoring you will be putting into place. Which distribution architecture are you using? You should know how many tiers your application will have and what application you will deploy to.
Diagramming is quick and easy with Lucidchart. Start a free trial today to start creating and collaborating. A variety of shapes make up deployment diagrams.
This list offers an overview of the basic elements you may encounter, and you can see most of these items illustrated in the image below. Association : A line that indicates a message or other type of communication between nodes. Dependency: A dashed line that ends in an arrow, which indicates that one node or component is dependent on another. Interface: A circle that indicates a contractual relationship. Those objects that realize the interface must complete some sort of obligation.
Node as container: A node that contains another node inside of it—such as in the example below, where the nodes contain components. Stereotype: A device contained within the node, presented at the top of the node, with the name bracketed by double arrows. Specification level deployment diagram - web application deployed to Tomcat JSP server and database schemas - to database system. In the example below, web application is deployed to the application server wsrv and several database schemas - to the database server dbsrv Instance level deployment diagram - web application deployed to Tomcat JSP server and database schemas - to database system.
Deployment diagrams could be used to show logical or physical network architecture of the system. Network architecture diagram could show no artifacts or deployments at all or only the major ones.
Network architecture diagrams. Manifestation of components by artifacts. A node is the main tool in the deployment diagram. It describes the execution of the codes and how the system components interact with one another. A node can be a software or hardware object. Nodes house and execute the artifacts. Mostly, a node is a physical entity.
This type of node houses other nodes. This notation depicts the real software product the developers are working on. This notation represents other software elements present in the system. The symbol for the component notation is a rectangle with two tabs.
For instance, a bank application running on an Android device is a component of the node Android device. This notation indicates a contractual relationship between two elements. Its symbol is a circle with a connector line. What else is it really important to know? Every tool in software engineering is there for a reason and solves a problem.
