💵 Cost At-a-Glance

Monthly Total: ~$25–$60 | Annual: ~$300–$720

Budget: $500–$2,000/month (soft) | Utilization: ~2–12% ($25–$60 of $500–$2,000)

Status	Indicator
Cost Trend	➡️ Stable (dev environment, fixed workload)
Savings Available	💰 Minimal — already at lowest viable tiers
Compliance	✅ GDPR aligned — swedencentral EU data residency

✅ Decision Summary

• ✅ Approved: Free/Basic/B1 SKUs across all services for dev-only workload
• ⏳ Deferred: Private endpoints, WAF, Redis cache, multi-region, CI/CD infrastructure
• 🔁 Redesign Trigger: Production promotion requires S1+ App Service (autoscaling), SQL S0+ (capacity), and private networking (+$100–$300/month)

Confidence: Medium | Expected Variance: ±20% (partial MCP resolution; monitoring costs depend on actual data ingestion volume)

🔁 Requirements → Cost Mapping

📊 Top 5 Cost Drivers

💡 Quick Win: Set Application Insights daily cap to 0.5 GB/day to prevent unexpected monitoring cost spikes.

1️⃣ Azure App Service (B1 Linux)

2️⃣ Application Insights + Log Analytics

3️⃣ Azure SQL Database (Basic)

🏛️ Architecture Overview

Cost Distribution

Month-over-Month Projection

Cost projection assumes stable dev workload with no user growth in months 1-3, gradual increase to 100 users in months 4-6. App Insights data volume scales proportionally with traffic.

Key Design Decisions Affecting Cost

🧾 What We Are Not Paying For (Yet)

• Private endpoints (~$7.30/endpoint × 3 = ~$22/mo) — not needed for dev
• Azure Cache for Redis (Basic C0 ~$55/mo) — not needed for <100 users
• Azure Front Door / WAF (Standard ~$35/mo + $25/mo WAF policy) — deferred
• DDoS Protection Standard (~$2,944/mo) — using platform Basic DDoS
• Multi-region replication (SQL geo-replication ~$5–$15/mo) — single region for dev
• CI/CD infrastructure (GitHub Actions minutes — free tier for public repos)
• Microsoft Defender for Cloud (Free tier available; paid plans from $15/server/mo)

Assumptions & Uncertainty

• 730 hours/month assumed for always-on compute resources
• Data ingestion: ~0.5 GB/day for App Insights (may be lower in dev with minimal traffic)
• Network egress: <5 GB/month for <100 users (charged at ~$0.087/GB after first 100 GB free)
• Key Vault operations: ~1000 operations/month (negligible cost)
• SQL storage: <2 GB (within Basic tier's 2 GB included limit)
• MCP pricing gaps: SQL Database Basic, App Insights, and Log Analytics unresolved by MCP — ranges from requirements guardrails used

⚠️ Cost Risk Indicators

⚠️ Watch Item: Application Insights data ingestion is the primary cost uncertainty — a misconfigured logging level could increase monitoring costs 3–5×.

"If you need X, expect to pay Y more"

💰 Savings Opportunities

Total Potential Savings: Minimal

Already at lowest viable tiers. Further savings only possible by:

Strategy	Commitment	Monthly Savings	Annual Savings	% Reduction
App Insights daily cap	None	~$10–$20	~$120–$240	~30%
SQL Serverless (if avail.)	None	~$3–$5	~$36–$60	~10%
Dev/Test Pricing (MSDN)	MSDN sub	~$5–$10	~$60–$120	~15%
Free F1 App Service	None	$13.14	$157.68	100% compute

[!NOTE] Reserved Instances and Savings Plans are not recommended for this dev-only workload due to the small spend and uncertain commitment duration. Free F1 App Service drops always-on capability — acceptable only if API cold starts are tolerable.

🧾 Detailed Cost Breakdown

Assumptions

• Hours: 730 hours/month (always-on)
• Network egress: <5 GB/month (within free tier)
• Storage: <2 GB SQL (within Basic included)
• App Insights ingestion: 0.5 GB/day (15 GB/month; first 5 GB free)

Line Items

Notes

• MCP Resolution: Only App Service B1 ($13.14/mo) was fully confirmed by azure_bulk_estimate. SQL Database Basic, App Insights, and Log Analytics returned SKU mismatches. Ranges are conservative estimates from requirements component guardrails.
• Free tiers: Static Web Apps Free (100 GB bandwidth, 2 custom domains), Entra External ID (50K MAU), and first 5 GB/month App Insights ingestion provide zero-cost baselines.
• No reservation eligibility: At <$60/month total, reserved instances would not provide meaningful savings.
• Dev/Test pricing: If team has MSDN/Visual Studio subscriptions, Azure Dev/Test pricing provides additional discounts.
• Region comparison: azure_region_recommend showed App Service B1 is ≤$0.017/hr in cheaper regions (eastus, westus3) vs $0.018/hr in swedencentral — ~5% difference ($0.73/mo), not worth relocating for GDPR compliance reasons.
