3-year cost calculator
Pre-filled for Amazon Web Services → Microsoft Azure. 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 Microsoft Azure
Common trade-offs teams weigh when staying on Amazon Web Services versus moving to Microsoft Azure. 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 + licensing
- Requires a migration (~18 weeks, high effort)
- Usage-based + licensing cost
- Higher operational learning curve
Why teams evaluate alternatives to Amazon Web Services
Reasons commonly cited by users and in public industry coverage for re-evaluating Amazon Web Services. These are general, reported considerations — not statements of fact about AWS — and may not reflect your situation or the vendor's current terms. Verify against your own contract before deciding.
- Egress and data-transfer fees add up fast
- Steady-state run cost can exceed on-prem
- Deep lock-in to proprietary managed services
The migration plan
Roughly 18 weeks for a mid-size estate, in six phases.
Tooling & automation
Use Azure Migrate (servers/VMs) and Azure Database Migration Service (DBs); rebuild infrastructure as code (Bicep/Terraform); sync S3→Blob, then cut over DNS during the window.
OffVendor's wizard pre-fills these scripts with your environment — inventory export, disk/schema conversion, bulk provisioning, and validation.
Frequently asked
Is migrating from Amazon Web Services to Microsoft Azure worth it?
For most teams facing rising Amazon Web Services costs, yes — Microsoft Azure (usage-based + licensing) typically lowers 3-year total cost of ownership, though the right answer depends on workload complexity and in-house skills. Use the calculator to model your own numbers.
How long does a Amazon Web Services to Microsoft Azure migration take?
A typical mid-size estimate is around 18 weeks across six phases — discovery, design, pilot, waved production migration, validation, and decommission. Larger or more complex estates take longer.
What tools are used to migrate from Amazon Web Services to Microsoft Azure?
