What is physical deployment?

Deployment diagrams are used to visualize the topology of the physical components of a system, where the software components are deployed. Deployment diagrams are used to describe the static deployment view of a system. Deployment diagrams consist of nodes and their relationships.

What are the differences between physical model and deployment views?

The physical model shows where and how system components will be deployed. It is a specific map of the physical layout of the system. A deployment diagram illustrates the physical deployment of the system into a production (or test) environment.

What are the different parts of deployment diagram?

In deployment diagrams, a device is a type of node that represents a physical computational resource in a system, such as an application server. A deployment specification is essentially a configuration file, such as an XML document or a text file, that defines how an artifact is deployed on a node.

What does a UML deployment diagram look like?

A UML deployment diagram is a diagram that shows the configuration of run time processing nodes and the components that live on them.

What do you mean by physical model in UML?

The Physical or Deployment Model provides a detailed model of the way components will be deployed across the system infrastructure. It details network capabilities, server specifications, hardware requirements and other information related to deploying the proposed system.

What are the nodes in a deployment diagram?

A deployment diagram consists of nodes. Nodes are nothing but physical hardware used to deploy the application. Deployment diagrams are useful for system engineers. An efficient deployment diagram is very important as it controls the following parameters −. Performance. Scalability. Maintainability. Portability.

How is the execution environment determined in UML?

For each deployment of component, aspects of these services may be determined by properties in a deployment specification for a particular kind of execution environment. Execution environment is notated the same way as a node (perspective, 3-dimensional view of a cube), annotated with the standard UML stereotype « executionEnvironment ».
