Hybrid Architecture Design

As of 2026-05-29

Hybrid architecture = 4 layers (S/4 embedded for sub-second, Datasphere for enterprise modeling, BDC for data product mesh + non-SAP, SAC for consumption). Three patterns: Federated Query Hub / Replication + Semantic Layer (canonical) / BDC Data Product Mesh. Five failure modes to pre-empt: latency mismatch, governance fragmentation, CU overrun, Cloud Connector bottleneck, skills gap. ADR required before architecture sign-off.
