Technology Layer Diagrams

A technology infrastructure diagram provides a high-level graphical view of the physical architecture required to support the application architecture.

Note: To create a technology infrastructure diagram in an existing EAM, right-click the model in the Browser and select New > Technology Infrastructure Diagram. To create a new model, select File > New Model, choose Enterprise Architecture Model as the model type and Technology Infrastructure Diagram as the first diagram, and then click OK.

A technology infrastructure diagram is the sole diagram in the technology layer.

In the following example, the deployment of servers within the company network is shown, along with the web access afforded to thin clients:

• Technology Infrastructure Diagram Objects
  PowerDesigner supports all the objects necessary to build technology infrastructure diagrams.
• Networks (EAM)
  A network allows computers to communicate with each other either locally or over large distances via telecommunications.
• Servers, Workstations, Mobile Devices, and Network Nodes (EAM)
  A software server is a commercial software environment, which contains a set of applications and which can be deployed to a hardware server. A hardware server is a device that serves data or other support to network devices and which usually has higher specifications than client devices. A workstation is a client machine to which an application or a server can be deployed. A mobile device is a portable client used remotely to access the network. Network nodes represent other type of network objects (routers, switches, firewalls, modems, printers, faxes, etc).
• Deployment Instances (EAM)
  A deployment instance is an instance of another object that is deployed on a server or elsewhere in the environment.
• Infrastructure Links (EAM)
  An infrastructure link is an oriented link that is used to connect objects in the technology layer.
