Business Applications

Using Business Applications

Device42 Business Applications offers a powerful way to build custom maps of business critical functions. Besides looking different than Affinity Groups, Business Applications are also different because they are not automatically built out based solely on discovered connections and devices. Business Applications can be totally designed and customized by you, and can include any and all of the resources that you identify as critical to your business!

Using Business Applications, you’ll be able to catalog all of your business and mission-critical applications. All of the following are possible:

• Creating Business Applications from scratch or from existing Affinity Groups
• Adding and removing devices and connectivity
• Customizing the resource layout, connections, and their labels
• Saving customized layout(s) and returning to edit them at any time

• Select Applications > Business Applications from the Device42 menu to display a list of existing applications.

• Click on a Business Application Name to view details about the application.

Note:  Business Applications display information about any Devices and Application Components associated with the Business Application. (Device42 automatically categorizes application components as Database, Application Layer, Web Server, Load Balancer, or Other.) Application Component information also appears on the Business Application visualization canvas (see below).

• Click View Application to see the visualization of the application.  Click the Edit button at the top right to turn edit mode on.

The page displays the business application name; hover over Application Details to see information about the application. The left panel contains icons for adding devices, affinity groups, or application components to your business application and a menu bar above the icons.  You can also now run a Service Dependencies Report for the Business Application, which details all the communications for the devices within the Business Application.

Click a device, affinity group, or application component object on the canvas to see details about that item. Links in the details box or below the object take you to the view pages for those items.

Add a Business Application

• Select Applications > Business Applications from the Device42 menu to display the applications list, and then click Add Business Application.

• Enter the application Name and select the Application Type (COTS, COTS with Customization, or Custom) and add a Description if wanted.
• Use the magnifying glass icons to select or enter the Technical Application Owner, Business Application Owner, and Responsible Customer or Department.
• Use the format 1w 2d 3h 4m 5s (1 week, 2 days, 3 hours, 4 minutes, and 5 seconds) to denote the time period for DR Recovery Point Objective and DR Recovery Time Objective. The individual terms are optional and numbers must be integers. For example, you can enter 2d 6h to define two days and six hours.
• Select or enter the Migration Group and Criticality, and add any Notes or Tags you want.
• Click Save at the bottom right of the page to save the application and add it to the applications list page.

Note: To edit an existing application, click its Name in the business applications list page, and then click Edit.
