Cloud Connector
Cloud Connector is the on-premise agent that establishes a secure reverse-invoke tunnel between SAP BTP subaccounts and internal (on-premise) systems, enabling BTP applications and Integration Suite scenarios to reach ERP/S4HANA and other backend systems without opening inbound firewall ports. This part covers its purpose, architecture, and core configuration including subaccount pairing, access control lists, and system mapping.

Lessons in this topic
- BTP Cloud Connector Part 1: How Cloud Connector WorksSAP Cloud Connector links on-premise systems to BTP securely. Learn installation options, how it opens an outbound TLS tunnel to a subaccount, supported protocols (HTTP, RFC, TCP, LDAP), and the principle of exposing only what's needed.
- BTP Cloud Connector Part 2: Subaccount Pairing, Access Control and System MappingConfigure Cloud Connector properly: subaccount definitions with location IDs, system mappings (back-end type, protocol, virtual/internal host), resources with path policies, principal propagation settings (system certificate, CA), audit logs, and testing from BTP.
- BTP Cloud Connector Part 3: High Availability, Multiple Connectors and OperationsRun Cloud Connector in production: master/shadow high availability, multiple connectors with location IDs for sites or load, monitoring (connections, performance, certificates), updates and backups, and a troubleshooting path for failed calls.
Interview questions covered
