SAP Fiori has revolutionized the user experience (UX) for SAP applications by providing a simple, role-based, and responsive interface accessible across devices. Understanding the architecture of SAP Fiori is essential for developers, architects, and business users to fully leverage its capabilities. At its core, SAP Fiori architecture is divided into two main components: the Frontend and the Backend. Together, these components work seamlessly to deliver modern SAP applications with improved usability and performance.
SAP Fiori architecture follows a client-server model with distinct roles for the frontend and backend:
This separation ensures flexibility, scalability, and enhanced user experience.
The SAP Fiori frontend is responsible for rendering the user interface and handling user interactions. It is typically implemented using SAPUI5, a HTML5-based UI development toolkit, which enables rich, responsive, and cross-platform user experiences.

The backend is where SAP Fiori’s business logic resides, typically hosted on an SAP NetWeaver Gateway or SAP S/4HANA system. It processes requests from the frontend and interacts with databases and other systems.

The frontend communicates with the backend primarily via OData services, a protocol that enables efficient data exchange over HTTP. When a user interacts with an SAP Fiori app, the frontend sends OData requests to read or update data. The backend processes these requests, performs the necessary business logic, and returns the response to the frontend.
This decoupled communication enables:
SAP Fiori’s architecture, divided into frontend and backend layers, enables a modern, responsive, and efficient user experience. The frontend—powered by SAPUI5 and the Fiori Launchpad—delivers an intuitive interface, while the backend—powered by SAP NetWeaver Gateway and business logic—ensures robust data processing and integration. Understanding this architecture is key to developing, deploying, and maintaining successful SAP Fiori applications.
