As organizations shift toward cloud-centric IT strategies, a hybrid approach often becomes essential—one that integrates cloud capabilities with existing on-premise systems. SAP S/4HANA Cloud, a leading intelligent ERP system, supports such hybrid landscapes by enabling seamless connectivity to on-premise environments. This article explores how to connect SAP S/4HANA Cloud to on-premise systems and the tools, technologies, and best practices that support such integration.
While SAP S/4HANA Cloud offers numerous advantages—scalability, reduced total cost of ownership, and faster innovation cycles—many enterprises still retain critical systems on-premise. Common reasons for connectivity include:
A typical hybrid SAP landscape may consist of:
The architecture often includes:
SAP Cloud Connector acts as a secure tunnel between on-premise systems and SAP BTP, enabling secure data exchange without exposing the internal network to the internet.
Key Features:
SAP Integration Suite (part of SAP BTP) allows for advanced integration scenarios using pre-built content, APIs, and adapters.
Capabilities include:
In SAP S/4HANA Cloud, integration is controlled through:
Here are common use cases for connecting SAP S/4HANA Cloud to on-premise systems:
