Describing a Computing Device
Accessing the list of computing devices
To access all the different types of computing devices:
1. From the Infrastructure navigation pane, select IT Devices > Computing Device.
2. Select IT Server tab.
The list of all computing devices appears:
• IT Servers,
• IT Devices,
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.
Creating a computing device
To create a computing device:
1. From the Infrastructure navigation pane, select IT Devices > Computing Devices.
2. Select IT Server tab.
The list of all IT Servers appears.
3. Click New.
4. Select the computing device type that you want to create and click Next.
5. Enter the Name of your computing device as well as its Owner and click OK.
The new computing device appears in the list.
Creating a Computing Device Assembly Diagram
To create a computing device assembly diagram:
1. Right-click the computing device and click Create Diagram.
2. Select Computing Device Assembly Diagram.
The diagram opens in the edit area.
You can insert the following in a computer assembly diagram:
• deployable Package Hosts, see Adding a deployable application package in an application deployment architecture diagram,
A deployable application package is a split of application code according to technical criteria for hosting purpose. For example, it may be N tiers, Front End/Back End/… or GUI/Business Logic/Database etc... Each deployable application package is associated to required technologies (for running) and can host code for several IT services. Architect can also prescribes a kind of hosting artefact (IaaS/PaaS cloud service or IT server model).• software technology hosts,
A software technology is a basic component necessary for operation of business applications. Software technologies include all basic software such as: application server, electronic mail server, software components for presentation, data entry, storage, business information sharing, operating systems, middleware, navigators, etc.• micro-service hosts,
A micro-service is a software component that can be deployed autonomously, but which does not directly provide an end user service. It can interact with other application services, applications or application systems. This is a deployable software component that uses software technologies. For example: an authentication service, a PDF file printing service.• data store hosts,
A data store provides a mechanism to update or consult data that will persist beyond the scope of the current process. It enables storage of input message flows, and their retransmission via one or several output message flows.• communication ports and channels,
• service and request points,
• interactions.
For more details on creation of these channels and the associated communication protocols, see Describing communications in an IT Infrastructure.
