Describing an IT infrastructure
*An IT infrastructure is made up of different hardware components such as: IoT and IT devices, computers or IT networks.
You can describe the components of an Infrastructure in an infrastructure assembly diagram.
Creating an IT infrastructure 
To create an IT infrastructure from the Infrastructure navigation pane:
1. Select II Infrastructures > IT Infrastructures.
The list of IT infrastructures appears.
2. Click New.
The Creation of IT technical device window appears.
3. Enter the Name of your infrastructure as well as its Owner and click OK.
The new IT infrastructure appears in the list.
Creating an Infrastructure Assembly Structure Diagram 
To create an infrastructure assembly structure diagram:
1. Right-click the IT infrastructure and select Create Diagram.
2. Select Infrastructure Assembly Structure Diagram.
The diagram opens in the edit area.
Using an Infrastructure Assembly Structure Diagram 
In an infrastructure assembly structure diagram, you can insert:
You can insert in this diagram:
• IT servers and IT devices, see Describing a Computing Device,
*An IT Server is an IT component providing a service to users connected via an IT network. This IT component can house databases and run applications.
*An IT device is a computer that provides a service directly to the end user. This computer can house databases and run applications. This is, for example, a workstation, a laptop or a smartphone.
• IoT Devices, see Describing a Computing Device,
*An IoT device is both a hardware device and a computing device which provides cvombined hardware and information services to the users using it directly. As a hardware device, it embeds sensors - e.g. accelerometer - which provide data to the embedded computing device. As a computing device, it can host data stores or run applications. Examples: smartwatch with GPS tracker, on-line surveillance video camera with live IP video feed, connected weighting scale with weight history management
• Network devices, see Describing an IT Technical Device,
*An IT device can host and run Software Technology. Conjointly with its hosted software, it provides technical services. This consists of, for example: Wifi Access Point, Firewall, router, switch, printer, Hard Drive.
• IT Network Components, see Describing an IT network,
*An IT network is set of IT equipment components (e.g.: routers, switches, firewalls) that allow remote communications between computing devices (e.g.: IT server). An IT network can be broken down into sub-networks.
• communication ports and channels, see Describing technical communications,
• interactions.
*An interaction represents a contract established in a specific context between autonomous entities that are internal or external to an enterprise. These entities can be enterprise org-units, applications, activities or processes, as well as external org-units. The content of this contract is described by an exchange contract.
*For more details on interactions, see Describing the services communications.
The Infrastructure description report allows you to analyze the infrastructure components and the expected relationships between them to verify that each element described in the diagram hosts a software or hardware component.
*For more details, see Infrastructure Description Report.
