The Application Portfolio Management team is asking for help modeling platforms as Business Applications.

The correct answer is C . In CSDM and Application Portfolio Management, a platform should be modeled as a Business Application with the architecture type Platform Host . Applications that run on or are provided by that platform should be modeled as Platform Applications and should reference the platform host. In this scenario, the ServiceNow Platform is the platform host, while Incident and Change are platform applications because they are capabilities delivered on the ServiceNow Platform. The relationship is not best represented by making all three applications generic web-based applications. That would lose the platform/application distinction. The preferred model is also not simply a Depends On relationship, because CSDM provides a more specific platform host reference model for this use case. Therefore, ServiceNow Platform should be Platform Host, and Incident and Change should be Platform Applications referencing ServiceNow Platform.
