Riyan Das 30 Reputation points

we are trying to move our on prem java web application running on apache tomcat to Azure VM. This application makes RFC(Remote function call) to on prem SAP systems to do some data transformation. Now if we move this solution to azure what are the options to connect to the on prem SAP system to make RFC calls ?

    Hello, @Das, Riyan !
    Edit: I've had this verified by a couple experts in this area so I'm going to move this to an answer for additional visibility. If you have any questions about ExpressRoute or site-to-site VPNs, feel free to start a new thread and we'd be happy to work with you!

    How do I connect to a on prem SAP system and run an RFC function from an Azure VM?

    Similar to what @JimmySalian-2011 suggested, the recommendation I received was to use a means to connect on-premises users and systems to Azure with either site-to-site VPN or express routes. With that, if the on-prem system is reachable by the Azure web app, RFC connection should be possible provided that networking firewall allows the connection.

    Hi Riyan,

    I will suggest you to explore Azure VPN gateway solution between the Azure and Onpremise Network - detailed design and requirements over here -

    Azure VPN is encrypted so traffic is secured and you can check VPN GW options over here -

    Hope this helps.
