**This blog post is updated on December 2020 **
Update: SAP Fiori front-end server 2020 for SAP S/4HANA will support SAP Business Suite with the release of Support Package SP01 (RTC planned for Q1 2021).
This blog post delivers a short summary of the different SAP Fiori front-end server versions and the related deployment options. For more details, please check the document SAP Fiori deployment options and system landscape recommendations.
SAP Fiori front-end server 6.0 is a long-term, stable UI technology foundation for SAP Fiori apps of SAP Business Suite and SAP S/4HANA systems, see also blog post. The end of maintenance of SAP Fiori FES 6.0 (end of 2027) relates directly to the maintenance period of SAP Business Suite.
SAP Fiori front-end server 6.0 and the predecessor versions can be deployed embedded or as a standalone server/hub for SAP S/4HANA and SAP Business Suite systems. The embedded deployment for SAP S/4HANA systems is the recommended setup. The standalone server deployment for SAP S/4HANA systems is mainly used by customers due to security aspects for external access scenarios.
In addition, for SAP Business Suite systems, the SAP Fiori front-end server can serve as central hub to offer a single entry point to multiple systems. This is not possible for an SAP S/4HANA system landscape, because of the version dependencies of the SAP Fiori UI components and backend versions.
The SAP Fiori front-end server versions up to 6.0 support all SAP S/4HANA and SAP Business Suite releases, down to SAP NetWeaver 7.40 based installations. This enables customers to consume new UI technology innovations by a selective upgrade of the SAP Fiori front-end server without touching the backend components.
SAP Fiori front-end server 2020 for SAP S/4HANA (released in October 2020) is a new front-end server version which was dedicated to the SAP S/4HANA product in the initial shipment version. Due to mandatory legal requirements related to accessibility, SAP will also release SAP Business Suite apps for SAP Fiori front-end server 2020 as of SP01. This allows customers to reach accessibility compliance for SAP Business Suite apps by using the new SAP Fiori front-end server version as a central hub or standalone server.
SAP Fiori front-end server 2020 for SAP S/4HANA (FES 2020) can be used for the latest three SAP S/4HANA releases: 1809, 1909 and 2020 and with the release of support package SP01 (RTC planned Q1/2021) also for SAP Business Suite systems. Lower SAP S/4HANA releases are not supported.
It contains the software components SAP_UI 7.55 including SAPUI5 version 1.78 and UIBAS001 600 in the initial shipment. The next support package will include the SAPUI5 long – term maintenance version 1.84 (planned for Q1/2021).
Both deployment options – embedded and hub (standalone server) are supported. The embedded deployment is the recommended one for SAP S/4HANA systems. In case of a standalone server deployment, the minimum SAP NetWeaver(NW) release is NW 7.52 SP06 for the initial shipment stack and NW 7.52 SP07 for FES 2020 Sp01.

SAP Fiori front-end server with SAP S/4HANA – upgrade options
As shown in the graph, you can upgrade the front-end server components to version SAP Fiori front-end server 2020 for SAP S/4HANA for 1809 and 1909 systems, without upgrading the S/4HANA product version. This is valid for the embedded and for a standalone server deployment.
Technically SAP Fiori front-end server 2020 for S/4HANA requires SAP NetWeaver 7.52 as the minimum release. This is required to be able to consume technology features, such as OData Version 4.0, and thus reduces technical limitations for future UI technology innovations.
For lower SAP S/4HANA releases an upgrade to the long-term maintenance version SAP Fiori front-end server 6.0 is recommended. Please refer also to this blog post.

Remark: In case you want to have IE11 support beyond the end of maintenance of FES 2020, which is end of 2023, you should stay with SAP FES 6.0.
As SAP Fiori front-end server 2020 for S/4HANA as of support package SP01 will support also SAP Business Suite apps, the scenario with a central front-end server hub with one SAP S/4HANA system and one or several SAP Business Suite systems (the so-called “mixed” scenario) is still a possible deployment option.
SAP’s strategic direction is to evolve powerful alternatives for a SAP Fiori front-end server as a central hub or standalone server with a much lower TCO on customer-side.
The central front-end server hub as a single entry point to multiple systems with the required UX integration capabilities is planned to be covered by the central SAP Fiori launchpad on SAP Cloud Platform, which will evolve further over times.
Currently alternatives for securing the backend systems without a SAP Fiori front-end server (e.g. in the DMZ network zone) for external access scenarios are being evaluated.
