From a system landscape architecture perspective, there are different ways to go about making SAP Fiori available to users. The SAP Fiori front-end server provides a means of deploying SAP Fiori to users. Let’s look at one of the SAP recommendations called “Central Hub Deployment”.

The Central Hub Deployment option enables the usage of multiple backend systems like SAP ERP, SAP SRM, SAP CRM and one S/4HANA on premise to run SAP Fiori apps. Customers with multiple S/4HANA systems on premise within their landscape can still use the hub to connect to the SAP Fiori launchpads of the connected SAP S/4HANA systems via custom Fiori launchpad tiles.

The following major aspects characterize this deployment option:

  • The SAP Fiori UIs are in general decoupled from the backend functionality (separate shipment)

  • The SAP Fiori front-end server offers a central deployment of the UIs and a central enablement of OData access for multiple SAP application backend systems

  • The SAP Fiori apps are deployed in separate systems (UIs in the SAP Fiori front-end server, related OData services in the backend systems)

Besides the Central Hub Deployment, there are also other possible landscape deployment recommendations for the SAP Fiori front-end server.

You can find basic information and an overview of currently recommended options in the SAP Enterprise Architecture Explorer. Users with the corresponding authorizations can also find information about SAP Fiori front-end server deployment for SAP S/4HANA in SAP Note 2590653.
