3-year cost calculator
Pre-filled for VMware vSphere → OpenStack. 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: vSphere licenses the physical CPU cores of each host (16-core minimum per CPU), not VMs. Count total physical cores across hosts and set $/core to your subscription tier.
All figures are illustrative and fully editable — adjust the cost-per-core 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: VMware vSphere vs OpenStack
Common trade-offs teams weigh when staying on VMware vSphere versus moving to OpenStack. 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
- Perpetual licenses eliminated — subscription-only renewals
- 160+ products collapsed into a few costly bundles
- Per-core pricing with 16-core-per-CPU minimums
- Widely reported 3–10× cost increases on renewal
- Ongoing per-core subscription cost to budget for
- Higher vendor lock-in to weigh
- Open source — no license fees
- No vendor lock-in
- Cost model: Free (self-managed)
- Requires a migration (~21 weeks, high effort)
- Community support by default — paid support optional
- Higher operational learning curve
