21.13 Reference Architectures & Architect Labs
Reference A — SAP-centric enterprise
S/4HANA + BW/4HANA -> Datasphere -> SAC
Use semantic onboarding, governed modeling and controlled analytical consumption.
Reference B — Hybrid enterprise
SAP + cloud warehouse + object storage + APIs -> Datasphere -> enterprise analytics
Use multiple integration patterns and keep ownership explicit.
Reference C — Domain data products
Domain sources -> domain spaces -> governed data products -> shared consumption
Use when multiple business domains need reusable data capabilities.
Lab 1 — Architecture selection
Given:
- 50 SAP sources
- 10 non-SAP sources
- 5,000 users
- near-real-time operational analytics
- monthly executive reporting
Design integration, semantic, security and consumption layers.
Lab 2 — Cost pressure
A platform has growing storage and integration workload. Propose changes without violating freshness SLOs.
Lab 3 — Security isolation
Finance and HR share a common employee-related dimension but have different access requirements. Design the sharing and security model.
Lab 4 — Acquisition failure
An S/4HANA source becomes unavailable for six hours. Define impact, fallback, recovery and reconciliation.
Lab 5 — Architecture review
Review a proposed design containing one giant space, copied datasets for every consumer and dashboard-level metric definitions. Identify at least ten architectural weaknesses.
