SAP Private Link service establishes a private connection between selected SAP BTP services and selected services in your own IaaS provider accounts. By reusing the private link functionality of SAP’s partner IaaS providers, the service lets you access your services through private network connections to avoid the need for public endpoints or data transfer via the public internet.
What does the BETA include?
With SAP Private Link service, Cloud Foundry applications running on SAP BTP with Microsoft Azure as IaaS provider can communicate with Azure Private Link services via a private connection. This ensures that traffic is not routed through the public internet but stays within the Azure infrastructure.

What are possible use cases?
One possible use case is to use the SAP Private Link service to communicate with an SAP S/4HANA system or other SAP or non-SAP system running on a VM in your own Azure account privately from within SAP BTP Cloud Foundry.
This connection can be established by creating an Azure Private Link service that exposes a loadbalancer which routes traffic to the SAP S/4HANA system. This Azure Private Link service must then be used as the resource to which the SAP Private Link service connects to. As soon as the connection is established successfully, the SAP Private Link service provides a private IP pointing to the Azure Private Link service.
You can also find the end-to-end S/4HANA extension scenario with step-by-step instructions in this repository.

How can I use it?
Check out the tutorials about how to
- Setup the SAP Private Link service in SAP BTP
- Connect SAP Private Link service to Microsoft Azure Private Link Service using the Cloud Foundry CLI
What to expect after BETA?
Currently, we only support the connection from SAP BTP Cloud Foundry to Azure Private Link services.
In the future, we plan to support:
- AWS as IaaS provider and the corresponding AWS PrivateLink service
- GCP as IaaS provider and the corresponding GCP Private Service Connect
- Connections to selected native Azure services, e.g. CosmosDB
- Connections initiated from within Azure to SAP BTP Cloud Foundry or other SAP BTP services
- Connections from other SAP BTP services
Please understand that SAP does not commit to, promise to, and is under no legal obligation to deliver these feature in the future. This list of features may be changed or withdrawn by SAP at any time for any reason without notice, and business decisions should not be based on this.
