3 Logical Architecture

Service list (name, purpose, Azure service choice, key Well-Architected pillar rationale)

4 Physical / Deployment View

Region(s), VNets, subnets, NSGs, AKS/App Service, storage tiers, etc.
Data-classification table & encryption choices

5 Cross-Cutting Concerns

Pillar	Design Tactics	Metrics / Alerts
Reliability	Zonal replica DB, retry patterns, chaos tests	Error budget %, RPO/RTO
Security	Zero-trust ingress, managed identities	MSTIC detections, pentest cadence
Performance Efficiency	Autoscale rules, caching strategy	P95 latency, cache hit ratio
Cost Optimization	Spot nodes, reserved instances	Monthly cost $, cost per user
Operational Excellence	CI/CD, IaC, observability	Deployment frequency, MTTR
