SAP River RDE to On-Premise Gateway without Cloud Connector

[former_member195440]

Hi,

I was just curious that all the guides I have found for setting up SAP River RDE to say, enhance an on-premise Gateway based Fiori application use the HANA Cloud Connector.

Is this an actual requirement or is there another way round this? I know that you will need to expose externally the OData/UI however does the Cloud connector do something else to make this work?

Thoughts and ideas please!

I guess it's just because using the cloud connector provides an easier mechanism than having to expose your on-premise Gateway server to the internet. I haven't tried it however there is the proxy option of 'internet' rather than 'on-premise' so I assume you could configure an internet facing gateway server.

Having said that, the Cloud connector does provide some security benefits, in terms of controlling the destination endpoints, audit logging of the requests in the HANA cloud platform etc.

Yes the cloud connector provides you access to your internal network resources.  If you have a system available on the internet, via a reverse proxy for example, you could then just create a destination in the HANA cloud platform that directly connects to it.  The following blog provides the details of connecting to the ES1 system which is a gateway test system available to all on the internet.

Thanks for your responses. This gave me enough information to work it out! I found this really useful page in the documentation - SAP Web IDE Developer Guide that talks about the various usages that need to be specified.

In the end I went with RDEUsage: odata_abap,ui5_execute_abap,dev_abap,bsp_execute_abap

The blog mentioned only stated odata_abap which would only allow for proxying OData requests but not make the system available to extend Fiori apps (which was my use case!).

Setting the "Proxy Type" to internet removes the need for a HANA Cloud Proxy install as my system is externally accessible.

Thanks for all your help on this.
