3-year cost calculator
Pre-filled for Amazon Web Services → Google Cloud. Adjust every figure with your own numbers.
Every figure here is an illustrative estimate, not a vendor quote. Defaults are editable starting points compiled from public information; real, binding pricing comes from the vendor or an authorized distributor. See our methodology.
How this is licensed: On-prem cost here is amortized hardware + power + ops per vCPU; cloud cost is usage-based. For steady-state workloads the cloud run-cost is often higher (so repatriation saves), while the cloud's value is elasticity, agility, and opex. Set $/vCPU to your real amortized or committed rates.
All figures are illustrative and fully editable — adjust the cost-per-vCPU and migration inputs with your own numbers. Not guaranteed vendor pricing (defaults reviewed May 2026). For a binding quote, use the request form below to reach an authorized distributor or partner.
Quick comparison: Amazon Web Services vs Google Cloud
Common trade-offs teams weigh when staying on Amazon Web Services versus moving to Google Cloud. These are general, commonly-reported considerations — not statements of fact about any vendor — so check them against your own contract and the vendors' current terms.
- Already in production — no migration effort or risk
- Mature ecosystem with vendor support and SLAs
- Egress and data-transfer fees add up fast
- Steady-state run cost can exceed on-prem
- Deep lock-in to proprietary managed services
- Ongoing usage-based (compute + egress) cost to budget for
- Higher vendor lock-in to weigh
- Commercial option with vendor support and SLAs
- Cost model: Usage-based
- Requires a migration (~18 weeks, high effort)
- Usage-based cost
- Higher operational learning curve
