| Compliance |
✅ None (internal tool) |
✅ Decision Summary
- ✅ Approved: Single-region, cost-optimized dev/test workload; keep SWA/Functions on free tiers
- ⏳ Deferred: Private endpoints, multi-region DR, dedicated always-warm compute
- 🔁 Redesign Trigger: If this becomes production-critical or traffic increases materially, SQL tier and SWA tier change
Confidence: Medium | Expected Variance: ±25% (SQL tier/usage and logs are the primary uncertainty)

Business Context
This workload is an internal tool for workflow validation testing.
The architecture intentionally optimizes for cost while meeting the stated 99.9% availability target for a
non-critical internal app.

🧾 What We Are Not Paying For (Yet)
- Multi-region DR (active-active or warm standby)
- Private endpoints for PaaS services
- Dedicated always-warm compute for Functions
- Higher SQL tier for sustained throughput
⚠️ Cost Risk Indicators
| Resource |
Risk Level |
Issue |
Mitigation |
| Azure SQL Database S0 |
🟡 Medium |
DTU saturation may require tier upgrade |
Alert on DTU > 80%, review monthly |
| Log ingestion |
🟡 Medium |
Exceeding free ingestion increases cost |
Cap verbosity; set retention targets |
| Data egress |
🟢 Low |
Low expected egress for internal users |
Monitor monthly egress |
⚠️ Watch Item: If transactions/day grows beyond projections, SQL tier upgrades become the primary cost driver.

🔧 Environment Strategy (FinOps)
- Production: Not applicable (design is dev/test).
- Non-prod: Keep SWA/Functions on free tiers; only upgrade SQL tier when DTU saturation persists.
