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?

When you think about it installation scripts are effectively “deployment source code”.

The ApplicationServer node contains EJBContainer a software node which in turn contains three software components, a deployment specification, and a software artifact. Deployment specifications are basically configuration files, such as an EJB deployment descriptor, which define how a node should operate.

In reality the software on the web server is communicating via the RMI protocol over the connection to the software on the application server. I may have chosen to apply the notation in “non-standard” ways. Remember, models evolve over time. To determine whether you need to create a deployment model, ask yourself this: The notation may have evolved from when I originally developed the diagrams.

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. 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.

Component Diagram

The physical connection between the physical hardware nodes is at a lower level, perhaps an Ethernet connection, so in reality I really 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.

Bottom line is that you’re going to be constrained by your tools anyway. Software elements are now simply listed by their physical filenames, information that developers are very likely to be interested in, and thus a more compact diagram is possible. 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.

They are used to illustrate the structure of arbitrarily complex systems. The information contained in Figure 2 can just as readily be captured in either a network diagram or a free-form diagram in combination with installation scripts. The UML evolves over time, and I may not have kept the diagrams up to date.

Connections between nodes are represented with simple lines, and are assigned stereotypes such as RMI and message diagarmme to indicate the type of connection. 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:.

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. This is particularly true when you are modeling an environment consisting of a many interconnected machines.

The unified modeling language reference manual temida. Distribute software to nodes. If you’re really concerned about the nuances of “official” UML notation then read the current version of the UML specification.

In unified modeling language uml, a component diagram depicts how components are wired together to form larger components or software systems. U,l2 this would be more accurate it would be a lot of work that I likely wouldn’t get much benefit from. Diagramme global dinteraction interaction overview diagram.

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. The unified modeling language reference manual james rumbaugh ivar jacobson grady booch addisonwesley an imprint of addison wesley longman, inc. When determining how to model the deployment architecture for a system, regardless of the artifacts chosen, I will typically: 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.

Identify the distribution architecture. Your distribution architecture strategy will often be predetermined for your application, particularly if you are deploying your system to an existing technical environment.

Your distribution strategy will define the general type of nodes you will have, but not the exact details. se

They are depicted as two-sectioned rectangles with the stereotype deployment specthe top df indicates the name and the bottom box lists the deployment properties if any for the node. I may have gotten it wrong in the first place. Translations Japanese Disclaimer The notation used in these diagrams, particularly the hand diagramme ones, may not conform perfectly to the current version of the UML for one or more of reasons: Gabays uml 2 analyse et conception pdf home ebooks.

A better example is shown in Figure 2.

In short, you may want to consider creating a deployment diagram for all but the most trivial of systems.
