Do you still need VMware?

There is no universal reason to leave VMware—and no universal reason to stay. The virtualization market has changed enough that organizations should periodically re-evaluate whether their current hypervisor still fits.

VMware Cloud Foundation and VMware vSphere Foundation 9 now use a subscription-based licensing workflow managed through VCF Operations rather than the traditional 25-character license-key model. At the same time, Proxmox VE and Microsoft Hyper-V provide capabilities that cover a large portion of what many small and midsize environments actually require.

Why virtualization strategy is worth revisiting

Infrastructure spending has become increasingly subscription-oriented. Hypervisor licensing, public-cloud compute, storage, backup, security and management platforms can all become permanent operating expenses.

Subscriptions are not inherently bad. They can provide continually maintained platforms and shift capital expense into operating expense. The problem is when recurring spend is never compared with realistic alternatives.

The FinOps Foundation’s 2025 State of FinOps report reflects this broader focus on understanding and optimizing technology spend beyond public cloud, including SaaS, licensing, private cloud and data-center costs.

Proxmox VE is no longer just a homelab answer

Proxmox VE combines KVM virtual machines and Linux containers with integrated web management, clustering, live migration, high availability and a broad storage model. Proxmox VE 9.2 added dynamic workload balancing and expanded software-defined networking capabilities in 2026.

That does not make Proxmox an automatic replacement for VMware. It does mean the platform deserves to be evaluated as a serious production option rather than dismissed as a lab hypervisor.

Where Proxmox can make sense

• Small and midsize clusters with predictable 24×7 workloads.
• Mixed Windows and Linux environments.
• Organizations that want integrated ZFS or Ceph options.
• Businesses seeking to reduce dependence on feature-tiered hypervisor licensing.
• Teams comfortable operating Linux-based infrastructure.
• Environments where backup, monitoring and application integrations have been validated.

Hyper-V remains a strong option

Hyper-V is not a legacy footnote. Windows Server 2025 supports live migration, and when paired with Failover Clustering it can provide highly available virtual-machine infrastructure. In Microsoft-heavy environments, existing skills and Windows integration can make Hyper-V a very sensible destination.

Teams should still account for clustering, storage, management and Windows lifecycle requirements rather than assuming “included with Windows” means operationally free.

VMware still has legitimate strengths

A migration project should never begin with the conclusion already decided. VMware can remain the right answer where third-party integrations, vendor certification, automation, operational expertise or the wider VMware ecosystem create enough value to justify the platform.

If the environment is stable, fully integrated and its cost is acceptable, changing hypervisors simply because alternatives exist may introduce more risk than value.

Then there is the cloud question

Cloud adoption is often discussed as though workloads naturally progress from local infrastructure to public cloud. That is not how every workload behaves economically.

A workload that runs continuously, uses predictable CPU and memory, consumes substantial local storage and primarily serves users at one or a few sites may not benefit from metered infrastructure indefinitely. A properly sized local virtualization cluster can make multi-year cost much more predictable.

Conversely, highly variable, globally distributed, short-lived or managed-service-dependent workloads may be poor candidates for local infrastructure.

What about cloud repatriation?

Cloud repatriation means moving workloads from public cloud back to private or on-premises infrastructure. It should not be treated as an ideological reversal of cloud adoption.

Sometimes the economics changed. Sometimes the workload turned out to be steadier than expected. Sometimes latency, data gravity, compliance, storage cost or operational control becomes the deciding factor. And sometimes, after doing the math, staying in the cloud is still the right answer.

How RMH IT evaluates the decision

We start with an inventory rather than a preferred hypervisor:

• Hosts, processors, memory and actual utilization.
• VM operating systems and application dependencies.
• Storage capacity, performance and growth.
• Network, VLAN and firewall requirements.
• Backup, replication and disaster-recovery dependencies.
• Availability objectives and acceptable downtime.
• Vendor support and certification requirements.
• Current licensing and cloud spend.
• Hardware lifecycle and support expectations.
• Internal skills and the operational cost of the target platform.

The migration is not the hard part—the dependencies are

Moving a virtual disk between platforms is only one part of a virtualization migration. The real risk lives in storage performance, virtual networking, backup compatibility, application support, guest drivers, HA behavior, maintenance procedures and rollback planning.

The takeaway

VMware is no longer the only credible answer for production virtualization. Proxmox VE has matured substantially, Hyper-V remains capable, and public cloud remains extremely valuable when the workload benefits from the cloud operating model.

The opportunity is not to pick a new favorite vendor. It is to stop treating infrastructure placement as a permanent decision and compare the technical and financial fit of each option.
