This is particularly true when you are modeling an environment consisting of a many interconnected machines. The unified modeling language reference manual, addisonwesley, To determine whether you need to create a deployment model, ask yourself this: How secure does the system need to be do you need a firewall, do you need to physically secure hardware, and so forth?
Remember, models evolve over time. Distribute software to nodes. Diagramme de composant notion de port bonjour, je suis en train d effectuer des recherches sur les diagrammes de composant en uml et je viens de dcouvrir la notion de port et je n arrive gref bretagne trouver un lieu d information et l.
When determining how to model the deployment architecture for a system, regardless of the artifacts chosen, Compsoant will typically:.
Another difference is that the concise version shows less details, not as many tagged values are shown as this information can be captured in either supporting documentation, configuration files, or source code. I’ve also used a drum as a visual stereotype for the University DB diagrakme, making it easier to distinguish on the diagram. Remember, agile models don’t need to be perfect, they need to be just barely good enough. The software components use the same notation as component diagrams I could have annotated them with their interfaces although that wouldn’t have added any value in my opinion.
Deployment diagrams can also be created to explore the architecture of embedded systems, showing how the hardware and software components work together. The UML evolves over time, and I may not have kept the diagrams up to date.

The unified compoxant language reference manual james rumbaugh ivar jacobson grady booch addisonwesley an imprint of addison wesley longman, inc. In reality the software on the web server is communicating via the RMI protocol over the connection to the software on the application server.
When determining how to model the deployment architecture for a system, regardless of the artifacts chosen, I will df I may have chosen to apply the notation in “non-standard” ways.
Translations Japanese Disclaimer The notation used in these diagrams, particularly the hand drawn ones, may not conform perfectly to the current version of the UML for one or more of reasons: Identify the distribution architecture.
Deployment diagrams tend to become very large very quickly because they reflect the physical complexities of your system, therefore a concise notation becomes critical to your success.
As you can see I didn’t indicate that WebServer is a device — it will at least be some sort of software artifact and very well may be one or more physical devices as well but my team hasn’t made that decision yet. Your distribution architecture strategy will often be predetermined for your application, particularly if you are deploying your system to an existing technical environment. I’d also need to model a dependency relationship between the software connection and the hardware connection, perhaps with the stereotype of over.
They are depicted as two-sectioned rectangles with the stereotype deployment specthe top box indicates the name and the bottom box lists the deployment properties if any for the node. The unified modeling language reference manual temida.
This is so far the most comprehensive book on uml 2. Connections between nodes are represented with simple lines, and are assigned stereotypes such as RMI and message bus to indicate the type of connection. As co,posant, it depends on your goals. Deployment models force you to think about important deployment issues long before you must deliver the actual system.
When you stop and think about it, the stereotypes that I’ve applied to the connections aren’t correct. Concise UML 2 deployment diagram. More cmposant, practice has shown that deployment modeling is well worth it.
It likely doesn’t matter anyway, because the modeling tool s that you’re using likely won’t fully support the current version of the UML notation perfectly anyway. Although this would be more accurate it would be a lot of work that I likely wouldn’t get much benefit from.
When I ask this question of the project teams I work with, we almost always decide to develop some form of deployment model. Bottom line is that you’re going to be constrained by your tools anyway. Physical nodes should be labeled with the stereotype deviceto indicate that it’s a physical device such as a computer or switch. A UML 2 deployment diagram depicts a static view of the run-time configuration of processing cokposant and the components that run on those nodes.
Will your application have two tiers, three tiers, or more? Both versions of the deployment diagrams indicate the software that is deployed on each node, critical information for anyone involved in development, installation, or operation of the system.

You need to make platform decisions, such as the hardware and operating systems to be deployed, including how the various nodes will be connected perhaps via RMI and a message bus as in Figure 2. Deployment specifications are basically configuration files, such as an EJB deployment descriptor, which define how a node should operate.
How robust does your system need to be will there be redundant hardware to failover to? They are used to illustrate the structure of arbitrarily complex systems.
