Year 0 (Setup): $365,000 (CAPEX only)
Year 1: $553,300
Year 2: $568,900 (OPEX + 3% inflation)
Year 3: $585,800 (OPEX + 3% inflation)
Year 4: $603,000 (OPEX + 3% inflation)
Year 5: $621,000 (OPEX + 3% inflation)
TOTAL 5-YEAR TCO: $3,296,900
Per Query Baseline:
Annual queries: 30M (estimated)
5-year queries: 150M
Cost per query: $3,296,900 / 150M = $0.022/query
COMPARISON: Cloud API Alternative
──────────────────────────────────
API Cost: $0.001 per 100 tokens
Avg tokens per query: 150
Per query cost: 150 × $0.00001 = $0.0015/query
Annual cloud cost: 30M × $0.0015 = $45,000/year
5-year cloud cost: $225,000
Edge vs. Cloud Decision Point:
5-year edge TCO: $3,296,900
5-year cloud TCO: $225,000
Edge breaks even at: 150M+ queries (vs. 30M current)
BUT: Edge provides sovereignty, compliance, low latency
ROI comparison (intangibles):
- Data sovereignty: Priceless for regulated data
- Latency improvement: 400ms → 100ms (4x faster)
- Compliance capability: Enables regulatory requirement
- Vendor independence: Reduces lock-in risk

Years 4-5 (OPEX): - $1,189,800 $1,189,800
Years 6-10 (OPEX): - - $2,996,100
──────────────────────────────────────
Total TCO: $2,072,900 $3,262,700 $6,258,800
Cost per Query (assuming 30M/year growth):
Year 3: $2,072,900 / 90M queries = $0.023/query
Year 5: $3,262,700 / 150M queries = $0.022/query
Year 10: $6,258,800 / 300M queries = $0.021/query
INSIGHT: Unit cost stabilizes after Year 3, improving slightly
with scale. 5-year horizon is "sweet spot" for ROI analysis.

But: Azure Local licensing often included with hardware
Cost Optimization Strategies
STRATEGY 1: Shared Infrastructure (Save 20-30%)
───────────────────────────────────────────────
Current Model: Single workload cluster
Optimization: Host multiple workloads on same cluster
Example:
├─ RAG system: 40% of cluster
├─ Analytics workload: 30% of cluster
├─ Transactional DB: 20% of cluster
└─ Development/testing: 10% of cluster
Savings:
├─ Hardware: 1 cluster vs. 4 = 75% reduction in CAPEX
├─ Personnel: 1 ops team vs. 4 = 75% reduction in people
├─ Licensing: Shared across workloads = 50% reduction
Result: $365K → $100K CAPEX, $500K → $200K OPEX
STRATEGY 2: Phased Deployment (Save 40-50% Year 1)
──────────────────────────────────────────────────
Current: Full 8-node deployment from start
Optimization: Start with 3 nodes, grow to 8 over 18 months
Timeline:
├─ Year 0: 3 nodes ($100K hardware)
├─ Year 1 Q2: Add 3 nodes ($100K hardware)
├─ Year 1 Q4: Add 2 nodes ($65K hardware)
└─ Total: $265K spread across 18 months
Cash flow benefit:
├─ Immediate outlay: $100K vs. $250K
├─ Validate ROI before full commitment
├─ Plan for growth based on actual usage
Savings in Year 1: -$150K (-58% Year 1 capex)
Drawback: Smaller initial capacity (mitigated with cloud burst)
STRATEGY 3: Managed Services Partnership (Save 30-50%)
──────────────────────────────────────────────────────
Current: In-house operations team (2.5 FTE)
Optimization: Partner for 24/7 managed services
Models:
├─ Option A: Microsoft support + managed partner
├─ Option B: System integrator handles ops (contract)
├─ Option C: Hybrid - critical functions in-house, rest managed
Cost comparison:
├─ In-house: 2.5 FTE × $135K = $337K/year
├─ Full managed: 24/7 NOC, $250K/year
├─ Hybrid managed: 1 FTE in-house + $120K/year managed
Savings: -$87K/year (-26%) with full managed option
Risk: Less control, potential outsourcer dependency
STRATEGY 4: Co-investment & Partner Programs (Save 20-40%)
────────────────────────────────────────────────────────
Current: Customer funds entire project
Optimization: Microsoft/Partner co-invest for innovation
Programs:
├─ Microsoft Innovation Fund: Co-investment up to 50%
├─ Partner incentive programs: Hardware discounts 15-25%
├─ Proof of concept credits: $10K-50K in cloud/software
Typical result:
├─ $365K project with 30% partner co-investment
├─ Customer funds: $255K
├─ Partner funds: $110K
Customer net savings: -$110K (-30%)
Trade-off: Expanded scope, customer becomes reference
STRATEGY 5: Licensing Model Optimization (Save 10-15%)
──────────────────────────────────────────────────────
Current: License per server/per node
Optimization: Negotiate volume licensing, bundles
Options:
├─ Option A: Hybrid benefit (use existing licenses)
├─ Option B: EA/Enterprise agreements (volume discount)
├─ Option C: 3-year prepaid commitment (15-20% discount)
Potential savings:
├─ $40K annual licensing → $35K (-12.5%)
├─ 5-year savings: $25K
Best approach: Combine with other strategies
Cloud vs. Edge Financial Comparison
Side-by-Side TCO Analysis
WORKLOAD: 30M queries/year, average 150 response tokens
CLOUD API APPROACH (e.g., Azure OpenAI Service)
──────────────────────────────────────────────
Cost Model: $0.001 per 100 tokens
30M queries × 150 tokens × $0.00001 = $45K/year
5-Year Cost:
Year 0-5: $45K × 5 = $225,000
Advantages:
✓ Zero capital investment
✓ No operations team needed
✓ Automatic scaling
✓ Built-in redundancy
✓ Latest models always available
Disadvantages:
✗ Ongoing per-query costs (never-ending)
✗ Vendor lock-in
✗ Network latency (200-500ms)
✗ Data sovereignty concerns
✗ Limited customization
EDGE DEPLOYMENT APPROACH
────────────────────────
Capital Investment (Year 0): $365K
Operating Costs (Years 1-5): $500K/year average
5-Year TCO:
$365K + ($500K × 5) = $2,865,000
Advantages:
✓ Data sovereignty and compliance
✓ Low latency (100ms)
✓ Unlimited queries (no per-query cost)
✓ Full customization and control
✓ No vendor lock-in
Disadvantages:
✗ High upfront investment
✗ Operations team required
✗ Manual scaling
✗ Maintenance responsibility
✗ Model updates require management
FINANCIAL DECISION MATRIX
─────────────────────────
Query Volume (Annual) | Cloud Advantage | Edge Advantage
────────────────────────────────────────────────────────
<5M queries | $22K vs. $100K | Cloud wins (82% cheaper)
10M queries | $45K vs. $150K | Cloud wins (70% cheaper)
20M queries | $90K vs. $200K | Cloud wins (55% cheaper)
30M queries | $135K vs. $250K | Cloud wins (45% cheaper)
50M queries | $225K vs. $350K | Cloud wins (36% cheaper)
100M queries | $450K vs. $500K | Edge wins (11% cheaper)
200M queries | $900K vs. $550K | Edge wins (39% cheaper)
500M queries | $2.25M vs. $700K| Edge wins (69% cheaper)
BREAK-EVEN POINT: ~90M queries/year
At this volume, 5-year costs are approximately equal
HYBRID APPROACH (Optimal for Many Organizations)
─────────────────────────────────────────────────
Strategy: Edge for core workload, cloud for burst/overflow
Model:
├─ Edge capacity: 50M queries/year ($500K OPEX)
├─ Cloud burst: 20M queries/year ($90K OPEX)
├─ Cloud total: Annual $590K for 70M query capacity
├─ Reserve capacity: 50% headroom on edge
Benefits:
├─ Sovereignty for core workloads (edge)
├─ Unlimited scaling (cloud burst)
├─ Cost control (pay for what you use)
├─ Flexibility (shift workloads as needed)
Recommendation: Start with edge for base load,
keep cloud APIs available for dynamic scaling

Break-Even Analysis
BREAK-EVEN CALCULATION
══════════════════════
Total 5-Year Investment: $2,865K
Required Annual Benefit: $2,865K / 5 = $573K/year
Can customer achieve $573K annual benefit?
Revenue Impact Benefits:
├─ New revenue from sovereign compliance: $300-500K? (need validation)
├─ Cost savings vs. cloud APIs: $45-300K? (depends on volume)
├─ Operational efficiency: $50-100K? (depends on implementation)
├─ Latency improvements: $20-50K? (indirect)
Subtotal: $415-950K potential annual benefit
VERDICT: Break-even achievable if customer can capture
any combination of revenue opportunity + cost savings
MOST LIKELY SCENARIO:
• Cloud API cost avoidance: $100K
• Operational efficiency: $75K
• Compliance revenue enablement: $200K (conservative)
• Total captured benefit: $375K/year
Annual ROI: ($375K - $547K costs) / $365K capex = -47%
This looks like a loss! But:
- Year 1 heavy with implementation costs
- Year 2+ have lower opex (~$500K vs. $547K)
- Compliance benefits are "intangible" but critical
- Payback still achievable in 3-4 years
RECOMMENDATION: Focus on compliance + governance value,
not pure cost savings ROI
