Uml deployment diagram tutorial pdf

To highlight the difference in simple terms, a Component diagram visualizes the process of grouping various elements of a system together. During the execution phase of a system, using UML Deployment diagram is essential. This is due to the complex amount of files, hardware and software involved in a single system.

On that note, there are several ways to get this type of diagram. One of them is by downloading templates, which are provided above. The other one is by making your own.

Difference between Component Diagram and Deployment Diagram Components of Deployment Diagram Like any other diagram, deployment diagrams are made up of several components and parts. Nodes — Nodes are used to represent the hardware and software within a single system.

It is represented by cube and is the physical element in the entire system. Artifacts — These are the core elements of a system which are the result of a certain process.

These files varies from Library, Archive, Executable and Config files. Artifacts in the UML deployment diagram are represented by a rectangular box. Communication Association — A rather simpler explanation for this element, is that it is a connector. It connects two different Nodes and shows a path of communication between Nodes.

Device Node — This element is technically a node that contains the computational resources within a system. Deployment Specifications — This element shows the sequence of configuration. Online Shopping Deployment Diagram Edit this example Online shopping is also a complicated system that needs extra attention. An instance can be distinguished from a node by the fact that its name is underlined and has a colon before its base node type. An instance may or may not have a name before the colon.

The following diagram shows a named instance of a computer. A number of standard stereotypes are provided for nodes, namely «cdrom», «cd-rom», «computer», «disk array», «pc», «pc client», «pc server», «secure», «server», «storage», «unix server», «user pc». These will display an appropriate icon in the top right corner of the node symbol. An artifact is a product of the software development process. That may include process models e.

An artifact is denoted by a rectangle showing the artifact name, the «artifact» keyword and a document icon, as shown below. Step 5: Besides, you can share your UML deployment diagram with others via social media and web page. One of the most powerful programs that can compete with Microsoft Visio, EdrawMax is yet another diagramming software available for Windows, macOS, and Linux.

The tool has several categories for almost all types of industries, and each category further has numerous templates to choose from, thus saving you a lot of time that you would otherwise waste in structuring a diagram, UML deployment diagram for this example, from scratch. Price : free to use, lifetime plan for individuals, license for team and business. Following are a few UML deployment diagram examples that would help you understand the diagram versatility.

This deployment diagram illustrates how a J2EE web application functions with load balancing and clustering. It has the benefit of showing which specific servers are involved in each step of the process. Requests to JSP pages are first load balanced, then forward to 2x2 Apache Tomcat servers via horizontal and vertical clustering.

It is a node that represents a physical machine capable of performing computations. A device can be a router or a server PC. It is a node that represents an environment in which software is going to execute.

For example, Java applications are executed in java virtual machine JVM. JVM is considered as an execution environment for Java applications. We can nest an execution environment into a device node. You can net more than one execution environments in a single device node.

Deployment diagram visualizes the topological view of an entire system. It represents the deployment of a system. A deployment diagram consists of nodes which describe the physical devices used inside the system. On these nodes, artifacts are deployed. We can also have node instances on which artifact instances are going to be implemented.

A deployment diagram plays a critical role during the administrative process, and it must satisfy the following parameters,. Nodes and artifacts are the essential elements of deployment. Before actually drawing the deployment diagram, all nodes and the relationship between every node of the system must be identified. You must know the architecture of a system, whether an application is a web application, cloud application, desktop application, or a mobile application.
