Multi-tenant architecture connection with the ERP

[juanforero5]

greetings experts,

Currently with our team we are developing a multi-tenant application, we are defining the architecture but a doubt arose.

how to make each tenat have its own connection to your ERP system taking into account the following image.

The idea is that each container has its own connection to its ERP system since it is required to read data, which will then be processed by the application and how to do so that the client can configure its connection parameters from the application,

Thank you very much for your help, any suggestion will be very well received.

If you could add more details like, where the ERP systems are, where the apps are going to be running, where the DBs are (I mean, on-prem or in BTP or in Azure etc.), it would help. This question is too vague to understand the context.

Thank you very much vijaykonam for your prompt response, the ERP systems are ompremise, the application will run in cloud foundry and we will use the hana cloud as a database.

If I understand you correctly, you are asking about how the DEV QA and PROD instances of this cloud application would talk to respective ERP systems on-premise?

IF so, you would use Cloud Connector settings per environment (DEV.QA and PROD) and expose the on premise ERP host with a pseudo name via RFC/HTTP protocol. You can then change the configurations in your cloud application instance.

If you are talking about same application talking to multiple ERP systems at one, it would also follow the same design as long as you maintain the Cloud Connector configurations for each of the ERP systems.
