Initial network connection setup in SAP IS or APIM or SAP Event Mesh

0 Kudos

Hello Experts,

We are planning to migrate PO to BTP (SAP IS or SAP Event Mesh).

I know that we need cloud connector to connect on-premise system to connect to SAP CPI , Do we need Cloud connector also for on-premise system connection in APIM or SAP Event Mesh?

How about connection setup when we wanted to connect to Cloud based systems in SAP CPI or APIM and SAP Event mesh? Please let me know also how to find out SAP CPI IP address to share to our partner systems?

When does Firewall comes in to picture ? When do we need Whitelisting ?

Could you please help me to understand clearly the initial network setup required to setup connection with Cloud based systems or on-premise systems? Please let me know the prerequisites required.

this is broad topic, but in general, yes, you will need Cloud Connector deployed and configured on-premise for any SAP Cloud services in BTP that wants to reach on-premise systems, in case you don't want to open the ports in firewall for such connectivity and in most of cases you don't want that.

More details and guidelines on Cloud Connector to be found here: Cloud Connector | SAP Help Portal

For IP Range of CPI please refer to below links:

hello Piotr,

It is clear that we need cloud connector to connect to on premise systems.

But how about if we need to setup connection to another partner system based on cloud?

I knew we need firewall clearance for a new interface while we do this in SAP PO.

Similarly I need to understand what are things to be taken care while setting up interface in SAP CPI or APIM or Event mesh.

I mean what are things to be known while building interface for another cloud based partner system.

Likewise what are things to be known while building interface for another on premise based partner system.

Thank you!
