What is a hybrid SAP landscape?

A hybrid landscape runs SAP systems across a mix of deployment models simultaneously — typically some combination of on-premise systems, private cloud (RISE with SAP), public cloud infrastructure, and SAP BTP-based extensions — rather than a single, uniform deployment model across the entire estate. Most large enterprises operate this way for extended periods, whether by deliberate strategy or as a natural consequence of transformation programs that migrate systems incrementally rather than all at once.

Rather than a temporary transitional state alone, hybrid is often a durable, long-term architecture for many organizations — some legacy systems may never fully migrate, making genuine hybrid operation a permanent architectural reality to design for, not just a waypoint on the journey to a fully cloud-native state.
