After Broadcom moved VMware to subscription-only bundles, VMware Cloud Foundation now lists at roughly $350 per core per year with a 16-core-per-CPU minimum, which is why a large share of buyers are pricing Proxmox VE, open source with optional support near $1,120 per socket per year, and Nutanix, licensed per core with bundled hyperconverged storage, against renewal quotes that have doubled or tripled. The decision is no longer VMware by default. It is a three-way cost, risk, and effort comparison where the cheapest license can carry the highest migration bill and the most expensive platform can still be the right answer for the most demanding estates.
This comparison sets out the 2026 cost picture for all three, the migration effort each demands, the support and risk profile, how to negotiate a Broadcom renewal if you stay, and where each one fits. The repricing itself is covered in our software contract negotiation guide; for firm-side help see our software licensing advisory.
What Broadcom changed
Broadcom retired VMware perpetual licenses and the old product menu, consolidating everything into two subscription bundles, VMware vSphere Foundation and the larger VMware Cloud Foundation, sold per core on annual or multi-year terms with a 16-core minimum per CPU. Standalone products that buyers used to license narrowly are now folded into bundles, so an organization that wanted only vSphere and vSAN frequently finds itself quoted the full stack. The practical effect for many mid-sized estates has been a two-to-threefold increase in annual cost at first renewal.
The 16-core minimum is its own cost driver. A server with two 8-core CPUs, 16 cores in reality, is still licensed as if it had 32 cores because each socket is rounded up to the 16-core floor. Older hardware with low core counts is penalized hardest, which is why the repricing has also accelerated hardware refresh decisions: if you are paying for 16 cores per socket regardless, you may as well populate the sockets with high-core-count chips and consolidate onto fewer hosts.
That shock is what put Proxmox and Nutanix on the shortlist. Neither is a drop-in replacement, and the migration is real engineering work, but the recurring cost gap is large enough that even a costly migration can pay back inside two to three years for the right estate. The comparison below prices the platforms and then weighs the switching cost that the license saving has to cover.
The 2026 cost comparison
The three platforms price on different units, so a fair comparison normalizes to annual cost for a representative host. The table below models a single dual-socket server with 32 cores total, a common building block, at list before negotiation.
| Platform | License basis | Representative annual cost, 32-core host | Storage |
|---|---|---|---|
| VMware Cloud Foundation | Per core, 16-core/CPU min | About $11,200 per year | vSAN bundled |
| VMware vSphere Foundation | Per core, 16-core/CPU min | About $4,500 to $6,400 per year | Add-on |
| Proxmox VE | Per socket support (optional) | About $2,240 per year (2 sockets, top tier) | Ceph / ZFS included |
| Nutanix Cloud Infrastructure | Per core subscription | About $9,000 to $13,000 per year | Bundled HCI storage |
Proxmox is the outlier on license cost because the hypervisor and clustering are free open source; you pay only for an optional support subscription per socket. Nutanix lands in the same range as VMware Cloud Foundation on license, but it bundles hyperconverged storage and management that would be separate or extra-cost elsewhere, so a like-for-like comparison must include what each price actually contains. VMware Cloud Foundation is the most expensive on paper and the most complete, which is precisely the bundling that the repricing made contentious.
Price the bundle contents, not the sticker: Nutanix and VMware Cloud Foundation include hyperconverged storage and management in the per-core price; Proxmox includes storage through Ceph or ZFS but support is optional and self-managed. Comparing a bare hypervisor cost to a full HCI stack overstates the saving. Normalize to the same delivered capability before deciding.
A three-year total cost model
License cost is only the visible part. A defensible decision models three years of license, support, migration, retraining, and the operational headcount each platform demands. The table below sketches a 20-host estate, 640 cores, to show how the picture shifts once migration is amortized.
| Cost line, 20-host estate | VMware VCF (stay) | Proxmox (migrate) | Nutanix (migrate) |
|---|---|---|---|
| Annual license / support | About $224,000 | About $45,000 | About $200,000 |
| One-time migration | None | $120,000 to $250,000 | $80,000 to $180,000 |
| Three-year total (indicative) | About $672,000 | About $300,000 | About $730,000 |
The model makes the trade explicit. Proxmox shows the largest three-year saving but loads almost all the risk and effort into a self-managed migration and ongoing self-support. Nutanix barely beats staying on VMware over three years once migration is counted, so its case rests on strategic fit and exit from Broadcom rather than near-term saving. Staying on VMware and negotiating the bundle scope and minimums down is often the lowest-risk way to recover a meaningful share of the increase without any migration at all.
One caution on the model: these figures are indicative and shift with core density, support tier, and the discount actually negotiated. A real decision rebuilds the table with the estate own host inventory, the workloads that must stay supported, and the specific renewal quote on the table, because the crossover point between staying and migrating moves substantially with each of those inputs. The point of the model is the method, not the round numbers.
Migration effort and hidden cost
The license saving only matters net of the cost to get there. Moving off VMware means converting virtual machine formats, rebuilding networking and storage integration, retraining operations staff, and revalidating backup, DR, and any third-party tooling certified only for vSphere. Proxmox and Nutanix both provide migration tooling, but the work scales with estate size and the number of integrated systems.
| Migration path | Typical effort | Main friction |
|---|---|---|
| VMware to Proxmox | High | VM conversion, new ops skills, no vendor hand-holding |
| VMware to Nutanix | Medium | Hardware/HCI alignment, lift via Nutanix Move tool |
| Stay on VMware, renegotiate | Low | Bundle scope and the per-core minimum |
For a small to mid estate, a Proxmox migration can be completed by an in-house team over a few months and pays back fast given the near-zero license cost. For a large, regulated, or tightly integrated estate, the migration risk and retraining can outweigh one or two renewal cycles of VMware cost, which is why some buyers stay on VMware and instead negotiate the bundle scope and minimums down. The renewal-negotiation route is detailed in our contract negotiation guide and supported by our software license management guide.
Ecosystem and tooling certification are the quiet third factor. Backup products, disaster-recovery orchestration, monitoring, and security agents are frequently certified and supported only against vSphere, and moving to Proxmox or Nutanix can mean replacing or revalidating part of that stack. The migration budget has to carry those secondary changes, not just the hypervisor swap, and in tightly integrated estates the dependent tooling, rather than the virtual machines, is what makes a move expensive.
Support and operational risk
The platforms differ sharply on who carries the operational risk. VMware and Nutanix are commercial products with vendor support, certified hardware compatibility lists, and a partner ecosystem, which matters in regulated and mission-critical environments where a supported configuration is a compliance requirement. Proxmox is open source with optional commercial support from its maintainer, which is capable but expects a competent in-house team and offers a smaller third-party ecosystem.
The risk question is not only technical. A self-supported platform shifts cost from license fees to staffing and on-call burden, and that trade only works if the team has the depth to carry it. For organizations that ran VMware as a managed appliance with a thin platform team, the honest comparison includes the cost of building the skills Proxmox assumes you already have, or the consulting to stand them up.
Count the people, not just the licenses: The Proxmox saving partly converts a license cost into a staffing cost. Before committing, confirm the team can carry self-support and on-call, or budget the hires and training that the open-source path assumes. A saving that creates an unplanned headcount gap is not a saving.
Negotiating the Broadcom renewal
For the many estates where migration is not worth the risk, the saving has to come from the contract itself, and there is more room than the first quote suggests. The levers are the bundle choice, vSphere Foundation rather than the fuller Cloud Foundation where the extra components are unused, the core count actually required after consolidation onto higher-density hosts, the term length traded for a better per-core rate, and a written cap on the renewal uplift so the increase does not repeat every cycle.
The credible alternative strengthens every one of those levers. A buyer who has genuinely scoped a Proxmox or Nutanix migration, even if they intend to stay, negotiates from a stronger position than one who has not, because the account team knows the switch is real. Arriving at the renewal with a costed migration plan, a consolidation model that lowers the licensable core count, and a benchmark of comparable per-core pricing is what turns a take-it-or-leave-it quote into a negotiation.
Where each platform fits
Proxmox suits cost-sensitive estates with capable Linux operations teams, lab and non-production workloads, and organizations comfortable owning their own support. Nutanix suits buyers who want a turnkey hyperconverged platform with a single vendor for compute, storage, and management, and who value an easier migration path off VMware than open source offers. VMware remains the strongest fit for the largest, most feature-dependent estates, those relying on NSX networking, advanced DR, or a deep ecosystem of vSphere-certified tools, provided the bundle and minimums are negotiated rather than accepted. In practice many large organizations land on a hybrid posture, keeping the most demanding production workloads on VMware while moving development, test, and lower-tier environments to Proxmox or Nutanix, which captures part of the saving without betting the most critical systems on a single migration.
The verdict: choose VMware, Proxmox, or Nutanix
Choose Proxmox when license cost is the dominant concern, you have or can build Linux and Ceph operations skills, and the estate is small enough that an in-house migration pays back quickly. The license saving is the largest of the three, but you are buying a self-supported platform.
Choose Nutanix when you want to leave VMware with the least re-architecture, value a single vendor for hyperconverged compute and storage, and can absorb a per-core cost in the VMware range in exchange for an easier migration and bundled HCI.
Stay on VMware when the estate depends on features and integrations no alternative matches cleanly, the migration risk to a large regulated environment is unacceptable, and the better move is to negotiate the Broadcom bundle scope, drop unneeded components, and cap the per-core minimum. In that case the saving comes from the contract, not a platform switch. For an independent read on which path your estate should take, see our software licensing advisory and negotiation guide.
