Break-even typically occurs at month 22 for workloads exceeding 15,000 monthly requests. Bare metal requires 40% higher upfront capital but reduces monthly OpEx by 65%. At year 5, local clusters save approximately 42% in cumulative costs, provided energy rates remain below 0.25 per kWh and hardware depreciation is linear over 60 months.
Purchase of NUCs or refurbished enterprise gear and networking switches.
Cumulative electricity costs and initial setup labor time.
Cumulative power costs plus first major component failure replacement.
Full 5-year power spend plus hardware depreciation totals.
Initial VPC configuration and EKS cluster bootstrap costs.
Monthly EKS management fee plus EC2 worker node hourly rates.
Cumulative cloud spend without asset ownership.
Total operational expenditure for five years of managed services.
Toggle high-probability external shocks to see how fragility surfaces in each path.
Regional electricity prices spike by 40%.
Unexpected 10x growth in request volume.
New Graviton instances reduce compute costs by 20%.
| Decision Dimension | Path A: Local Bare Metal K8s | Path B: AWS Cloud Scaling | Consequence Edge |
|---|---|---|---|
| Upfront Risk | High (Hardware Cost) | Negligible | Path B |
| Monthly Burn | Low (Electricity Only) | High (Subscription/Usage) | Path A |
| Operational Effort | High (SysAdmin) | Low (Managed) | Path B |
| 5-Year TCO | Lower (Asset Ownership) | Higher (Service Fees) | Path A |

When cumulative monthly AWS spend exceeds the amortized hardware cost + electricity, typically after 18-24 months for stable workloads.
At $0.25/kWh, power is a minor cost; if rates exceed $0.60/kWh, the break-even point pushes past month 36.
The 'Management Tax': spending 10+ hours/month on hardware maintenance instead of product development.
