# Configuring Outbound Communication
Outbound communication refers to message processing from the integration platform to a remote system \(where the integration platform is the client\).
Configuring outbound communication means setting up the connection of a remote receiver system with the integration platform.
## Receiver Systems You Can Connect to the Integration Platform
You can connect the following kinds of receiver systems to the integration platform \(examples\):
- A cloud application, for example, an SAP cloud application like SuccessFactors or SAP Cloud for Customer
- An on-premise application, for example SAP ERP
You can connect on-premise systems \(located in the customer system landscape\) such as SAP systems. Typical use cases for this are hybrid integration scenarios, where an on-premise SAP application \(for example, SAP ERP\) is integrated with an SAP cloud application \(for example, SAP Cloud for Customer or SAP SuccessFactors\).
- An e-mail server
In this case, the integration platform sends e-mails to the e-mail server \(for an e-mail address specified in the related adapter\).
- An SFTP server
In this case, the integration platform writes files to the SFTP server.
SAP Integration Suite supports the following kinds of connections: HTTP connections, SFTP \(SSH File Transfer Protocol\) connections, and connections to an e-mail server using the mail sender adapter.
