# Cloud Connector Learn more about the Cloud Connector: features, scenarios and setup. > ### Note: > This documentation refers to SAP BTP, multi-cloud foundation. If you are looking for information about the Neo environment, see [Connectivity for the Neo Environment](https://help.sap.com/viewer/b865ed651e414196b39f8922db2122c7/Cloud/en-US/5ceb84290d5644638f73d40fde3af5d0.html). ## Content **In this Topic** Hover over the elements for a description.

Click an element for more information.  ## Context The Cloud Connector: - Serves as a link between SAP BTP applications and on-premises systems. - Combines an easy setup with a clear configuration of the systems that are exposed to the SAP BTP. - Lets you use existing on-premises assets without exposing the entire internal landscape. - Runs as on-premises agent in a secured network. - Acts as a reverse invoke proxy between the on-premises network and SAP BTP. - Provides fine-grained control over: - On-premises systems and resources that can be accessed by cloud applications. - Cloud applications using the Cloud Connector. - Lets you use the features that are required for business-critical enterprise scenarios. - Recovers broken connections automatically. - Provides audit logging of inbound traffic and configuration changes. - Can be run in a high-availability setup.

For allowed outbound connections, no modifications are required. - The Cloud Connector supports HTTP as well as additional protocols. For example, the RFC protocol supports native access to ABAP systems by invoking function modules. - You can use the Cloud Connector to connect on-premises databases or BI tools to SAP HANA databases in the cloud. - The Cloud Connector lets you propagate the identity of cloud users to on-premises systems in a secure way. - Easy installation and configuration, which means that the Cloud Connector comes with a low TCO and is tailored to fit your cloud scenarios. - SAP provides standard support for the Cloud Connector.

This is particularly true for infrastructure \(IaaS\) hosting solutions. Here's an overview of all environments in which you can or cannot set up the Cloud Connector:
