 SAP Cloud Identity Services - Identity Authentication enables secure single sign-on (SSO) and user authentication for cloud-based applications.

 It is appropriate for enabling access to the custom application without adding users to the global directory. This ensures secure access while maintaining compliance with business and legal constraints.

 The service is designed for scenarios where temporary access or isolated authentication is required, as depicted in the provided diagram.(Reference: SAP Cloud Identity Services)

To establish connectivity between the end-user applications and the SAP S/4HANA on-premise backend system based on the attached diagram, the necessary components are:

Connectivity Service for Step 1:

SAP Connectivity Service establishes a secure communication channel for application requests between SAP Build Work Zone (in BTP) and the backend system.

It handles HTTPS-based communication protocols like OData for accessing the backend system's APIs.

Cloud Connector for Step 2:

SAP Cloud Connector ensures secure communication between the SAP BTP subaccount and the on-premise SAP S/4HANA system.

It creates a secure tunnel for data exchange, allowing Work Zone or other BTP services to access on-premise resources without exposing them directly to the internet.

This combination is the most suitable for maintaining secure and efficient connectivity while aligning with SAP-recommended best practices for hybrid integrations.
