How secure does the system need to be do you need a firewall, do you need to physically secure hardware, and so forth? Deployment diagrams can also be created to explore the architecture of embedded systems, showing how the hardware and software components work together. In reality the software on the web server is communicating via the RMI protocol over the connection to the software on the application server.
Do you intend to take a fat-client approach where the business logic is contained in a desktop application or a thin-client approach where business logic is deployed to an application server?
Component Diagram syntax and features
The physical connection between the physical hardware nodes is at a lower level, perhaps an Ethernet connection, so in reality I diagramm should have modeled a connection between the hardware nodes with Ethernet as a stereotype and a second connection between software elements with the RMI stereotype. Remember, models evolve over time. They are depicted as two-sectioned ce with the stereotype deployment specthe top box indicates the name and the bottom box lists the deployment properties if any for the node.
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.
I may have chosen to apply the notation in “non-standard” ways. In my opinion the deployment properties is superfluous as this is the type of information that is contained in the actual deployment specification file at run time.

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 conposant documentation, configuration files, or source code. A UML 2 deployment diagram depicts a static view of the run-time configuration of processing nodes and the components that run on those nodes.
Software artifacts are shown with the visual stereotype of a page with a folded corner or with the textual stereotype artifact or both sometimes, which I also believe is superfluous. Physical nodes should be labeled with the stereotype deviceto indicate that it’s a compoaant device such as a computer or switch.
More important, practice has shown that deployment modeling is well worth it. You want to create a deployment compossnt for applications that are deployed to several machines, for example a point-of-sales application running on a thin-client network computer which interacts with several internal servers behind your corporate firewall or a customer service system deployed using a web services architecture such as Microsoft’s.
If you’re really concerned about the nuances of “official” UML notation then read the current version of the UML specification. Identify the nodes and their connections.
Bottom line is that you’re going to be constrained by your tools anyway. Diagrammw 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. As always, it depends on your goals.

Does the diagram address how to deploy a version of a single application or does it depict the deployment of all systems within your organization? Les participants n ont pas besoin d etre explicitement declares.
Will your application have two tiers, three tiers, or more?
A better example is shown in Figure 2. Sometimes comosant high-level free-form diagram is a better option because the notation is much more flexible. The unified modeling language reference manual, second edition if you are a serious user of uml, there is no other book quite like this one.
The three-dimensional boxes represent nodes, either software or hardware. Although this would be more accurate diagrmme would be a lot of work that I likely wouldn’t get much benefit from.
When you stop and think about it, the stereotypes that I’ve applied to the connections aren’t correct.
Deployment specifications are basically configuration files, such as an EJB deployment descriptor, which define how a cojposant should operate. I never draw deployment diagrams following the style show in Figure 1except when I’m writing about deployment modeling, because in my opinion this notation is visually wasteful.
An agile modeler is more interested in created models which communicate effectively than in conforming to notation rules set by a committee.
