Architect SAP on Azure

SAP S/4HANA and SAP Fiori

SAP S/4HANA and SAP Fiori

• The Web User Interface for SAP S/4HANA is SAP Fiori accessed through a web browser

​

• SAP Fiori has a major impact on the overall system architecture

​

• SAP Fiori may be combined with SAP S/4HANA, which is called an embedded deployment and it is the recommended scenario from SAP when it will be used exclusively with S/4HANA

​

• SAP Fiori can also be deployed as a completely separate system, with its own application servers and
  database

​

• To optimize the solution SAP Fiori need to stacking its databases together using SAP HANA Multitenant Database Containers (MDCs)

​

• SAP Fiori is accessed through the HTTP protocol and placing a SAP Web Dispatcher reverse-proxy can accept or reject a user connection and load balance traffic between multiple application servers

​

​

​

​

​

• The SAP Web Dispatcher should be deployed in the DMZ area of the network

​

• A highly available SAP landscape should include a highly available SAP Web Dispatcher that runs on two VMs with load balancer in front of it

​

• Azure Application Gateway solution, which works on the application layer and provides additional network capabilities is a solution for the load balancer

​

• Combining both SAP Web Dispatcher and Application Gateway solutions gives the best results
