Option C: Structuring the SAP BTP account model with one global account and directories for each region allows logical separation of resources within a shared global framework. Directories help in managing quotas, access, and usage within each region while maintaining global oversight.
Option D: Alternatively, creating a global account with subaccounts for each region offers clear boundaries for resource allocation, access control, and cost analysis. Each subaccount can track usage and expenses independently.
Both models support cost control and geographically distributed IT staff management while allowing global visibility and governance.(Reference: SAP BTP Global Account and Subaccount Management)
