Broadcom’s acquisition of VMware in late 2023 had predictable consequences and some unpredictable ones. The predictable part: licensing costs rose sharply, sometimes by multiples, as Broadcom moved customers onto bundled subscription models and discontinued perpetual licenses. The less predictable part: the exodus happened faster than most analysts expected. By 2025, organizations that had been on VMware for a decade were actively migrating, and the question shifted from whether to migrate to which platform to migrate to.
The answer depends on what kind of organization you are. A cloud-native team that had been running VMware largely out of inertia will have different requirements from a regulated enterprise whose VMware environment underpins its operational resilience obligations. This comparison covers seven alternatives across that spectrum, starting with the cloud-native end.
| # | Platform | Type | Licensing | Migration Difficulty | Kubernetes Support | Sovereign Option |
| 1 | Civo | Sovereign cloud platform | Pay-per-use | Low (for cloud-native) | Native | Yes |
| 2 | Proxmox VE | Open-source hypervisor | Free / €115/yr enterprise | Medium | Via add-ons | Self-managed |
| 3 | Nutanix AHV | Enterprise HCI | Subscription | Low-Medium | Yes (NKP) | Self-managed |
| 4 | XCP-ng / Vates | Open-source hypervisor | Free / commercial | Medium | Via add-ons | Self-managed |
| 5 | Scale Computing HC3 | SMB HCI platform | Subscription | Low | No | Self-managed |
| 6 | OpenStack (Canonical) | Open-source cloud | Free / support subscription | High | Yes | Self-managed |
| 7 | SUSE Harvester | Open-source HCI | Free / SUSE support | Medium-High | Native (K8s-based) | Self-managed |
Civo
The VMware migration conversation tends to focus on replacing VMware with another virtualization platform. That’s the right question for organizations that need to keep workloads on-premises for sovereignty, compliance, or latency reasons. But for a significant share of VMware-hosted workloads – particularly web applications, microservices, CI/CD pipelines, and ML infrastructure – the migration is better framed as an opportunity to move to cloud-native infrastructure that never needed a hypervisor in the first place.
Civo’s Kubernetes-native platform is built for exactly those workloads. Containerized applications that were running in VMware VMs largely for convenience can move to Civo’s managed Kubernetes environment without re-architecture: the application logic stays the same, the operational layer becomes significantly simpler, and the platform handles cluster provisioning, scaling, and lifecycle management. Kubernetes clusters provision in under 90 seconds.
For organizations in regulated sectors – and a high proportion of long-standing VMware customers are regulated organizations – Civo’s UK and EU sovereign cloud options address the compliance questions that complicate moving away from on-premises VMware. ISO 27001, SOC 2, and Cyber Essentials certification, G-Cloud 14 listing, and contractually guaranteed UK data residency mean that the cloud migration doesn’t introduce a compliance gap. GPU instances (A100, H100, B200) within the sovereign boundary enable AI workloads that couldn’t easily run in a VMware environment.
- Kubernetes-native platform; sub-90-second cluster provisioning
- Best suited for containerized and cloud-native workloads migrating off VMware
- ISO 27001, SOC 2, and Cyber Essentials certified; G-Cloud 14 listed
- UK and EU sovereign cloud with contractually guaranteed data residency
- Zero egress fees; transparent billing; A100, H100, and B200 GPU instances
- $250 free trial credit for one month
Proxmox VE
Proxmox VE has become the default recommendation for organizations that need a direct VMware replacement on existing hardware. It’s open-source, free at the base level, and provides the core enterprise virtualization capabilities that VMware users rely on: KVM full virtualization, LXC containers, high availability clustering, live migration, storage replication, and a built-in backup server.
The optional enterprise subscription starts from approximately €115 per CPU socket per year, granting access to the stable enterprise repository and SLA-backed support. By comparison, VMware vSphere Foundation under Broadcom’s subscription model runs to approximately €4,500 per CPU socket per year. The cost saving is significant enough that organizations have cited it as the primary migration driver. VM format conversion from VMware’s VMDK to QEMU’s qcow2 is documented and supported, though large-scale migrations require careful planning and staging.
- KVM virtualization plus LXC containers in a single platform
- Free open-source base; enterprise subscription from €115/CPU/year
- HA clustering, live migration, Ceph storage, built-in backup server
- Active community; extensive documentation; growing ecosystem of enterprise partners
Nutanix AHV
Nutanix positions itself as a full VMware replacement rather than a hypervisor alternative: its HCI platform bundles compute, storage, and virtualization into a single architecture managed through a unified Prism interface. AHV (the Nutanix hypervisor) is included at no additional cost with Nutanix licenses. The migration tooling, including Nutanix Move, automates VM migration from VMware with minimal downtime.
The platform suits enterprises that want VMware’s feature depth and management polish without VMware’s licensing structure. Nutanix’s subscription model is less expensive than Broadcom-era VMware for most organizations, while providing comparable operational capabilities. The trade-off is vendor lock-in: Nutanix’s tightly integrated stack simplifies operations but commits the organization to a single vendor in the same way VMware did.
- Full HCI platform: compute, storage, and AHV hypervisor in one architecture
- Nutanix Move tool automates VM migration from VMware
- Prism management interface; enterprise feature parity with VMware
- Subscription pricing; lock-in risk similar to VMware
XCP-ng / Vates
XCP-ng is an open-source Xen-based hypervisor maintained by Vates, a French company that provides commercial support and the Xen Orchestra management interface. It offers a VMware-like operational experience – VM lifecycle management, HA, live migration, storage management – on a fully open-source foundation with no per-VM or per-socket licensing.
For organizations that found Proxmox’s KVM-based approach too different from VMware’s architecture, XCP-ng’s Xen foundation offers a more familiar virtualization model. The active community and Vates commercial support options provide an enterprise-grade option for organizations that need SLA-backed support without VMware licensing costs. Migration from VMware requires VM format conversion, similar to Proxmox.
- Xen-based open-source hypervisor; free with optional Vates commercial support
- Xen Orchestra management UI; HA, live migration, storage management
- More familiar to VMware-experienced teams than KVM-based alternatives
- French-owned commercial support via Vates
Scale Computing HC3
Scale Computing targets the SMB and edge computing market with its HC3 hyperconverged platform. It’s designed for organizations that want simple, low-maintenance virtualization infrastructure with minimal IT overhead – a common profile among organizations whose VMware deployments were smaller and whose primary concern after the licensing shock is avoiding operational complexity, not adding it.
HC3 clusters are managed through a single interface, scale horizontally by adding nodes, and handle VM migration from VMware via Scale Computing’s migration tool. The platform is not suited to large enterprise deployments or complex workloads, but for smaller organizations running a manageable number of VMs and looking for a straightforward exit from VMware costs, it’s a practical choice.
- HCI platform targeted at SMB and edge deployments
- Simple node-based scaling; minimal IT overhead
- Migration tooling from VMware supported
- Not suited to large enterprise or complex workload requirements
OpenStack (Canonical Distribution)
OpenStack is the open-source cloud infrastructure platform used by many major cloud providers and large enterprises. The Canonical Distribution of Ubuntu OpenStack is the most widely deployed enterprise version, with commercial support and a documented migration path from VMware environments. It provides a full IaaS layer – compute, networking, storage, and orchestration – on commodity hardware.
OpenStack suits large organizations with significant in-house engineering capacity and complex workload requirements. The migration and operational complexity is higher than Proxmox or Nutanix, but the flexibility and scale ceiling are correspondingly greater. For organizations building private cloud infrastructure at scale rather than replacing VMware on a handful of clusters, it’s the most capable open-source option.
- Full open-source IaaS; compute, networking, storage, and orchestration
- Canonical distribution with commercial support and upgrade paths
- Suited to large organizations with engineering capacity; complex to operate
- Industry-standard API compatibility with public cloud providers
SUSE Harvester
SUSE Harvester is an open-source hyperconverged infrastructure platform built natively on Kubernetes, combining KVM virtualization with container workloads in a single environment. It’s designed for organizations that want to run both VMs and containers on the same infrastructure without separate management planes, which is increasingly relevant for teams migrating VMware-hosted workloads that include a mix of legacy VMs and modern containerized applications.
Harvester integrates with Rancher for multi-cluster management and is backed by SUSE’s enterprise support. The migration difficulty is moderate to high, reflecting both the Kubernetes-native architecture and the relative immaturity of migration tooling compared to more established alternatives like Proxmox or Nutanix. For organizations committed to a Kubernetes-first infrastructure strategy, Harvester’s native integration is a compelling long-term architecture.
- Open-source HCI built on Kubernetes; runs VMs and containers on shared infrastructure
- Rancher integration for multi-cluster management; SUSE enterprise support
- Native Kubernetes architecture; well-suited to Kubernetes-first infrastructure strategies
- Migration tooling less mature than Proxmox or Nutanix alternatives

What to Look for in a VMware Alternative
- Workload type first. Cloud-native and containerized workloads are better moved to a cloud platform than a VMware replacement. Legacy and stateful VMs typically need an on-premises hypervisor or HCI solution. The right answer depends on what the workloads actually are, not just what VMware was doing.
- Migration tooling. How well the platform handles VM format conversion, network remapping, and storage migration determines how disruptive the transition is. Assess migration tooling specifically, not just the destination platform’s features.
- Licensing model longevity. The primary reason organizations are leaving VMware is a licensing model change. Before committing to any alternative, evaluate whether the licensing model is sustainable over a 5 to 10-year horizon. Open-source platforms with optional commercial support are structurally more stable here than commercial platforms with subscription models.
- Support structure. Open-source platforms offer community support, commercial subscriptions, and third-party partners. Evaluate which combination your team needs – particularly if you’re reducing VMware-specific expertise as part of the migration.
- Compliance and sovereignty. If your VMware environment was hosting regulated workloads, the alternative needs equivalent or stronger compliance credentials. Moving to a less-certified platform to save on licensing is a compliance risk as well as a cost decision.
Frequently Asked Questions
Why are so many organizations leaving VMware in 2026? Broadcom’s acquisition of VMware in 2023 resulted in significant licensing cost increases, the discontinuation of perpetual licenses in favor of subscription bundles, and a strategic pivot toward large enterprise customers. Organizations that had been paying manageable perpetual license fees found themselves facing subscription costs that were, in some cases, three to five times higher. The migration wave that followed is the natural consequence of that pricing shift.
Is Proxmox genuinely enterprise-ready, or is it still primarily for smaller deployments? Proxmox VE 9, released in August 2025, added enterprise capabilities including centralized multi-site management (Proxmox Datacenter Manager) that bring it closer to vCenter-level functionality. It’s used at enterprise scale by managed service providers and hosting companies globally. The main gap versus VMware is third-party ecosystem depth – backup, monitoring, and management tool integrations are less extensive than VMware’s mature partner network.
Can regulated organizations migrate from VMware to cloud-native infrastructure? Yes, if the cloud platform meets their compliance requirements. The key questions are data residency, jurisdictional governance, and certification scope. Sovereign cloud platforms with ISO 27001 certification, contractual residency guarantees, and G-Cloud listing can accommodate regulated workloads that VMware was previously hosting on-premises. The migration also requires verifying that application-level compliance controls are maintained through the transition.
How long does a typical VMware to Proxmox migration take? It depends on the environment size, workload complexity, and whether VMs can be migrated with downtime or need live migration. Small environments (under 20 VMs) can often be migrated within days; larger environments with complex network configurations, storage dependencies, and zero-downtime requirements can take weeks to months with proper staging and testing. All sources recommend migrating non-critical workloads first.
What happens to VMware licenses after migration? Once you terminate the VMware subscription, access ends. Organizations should plan migration to be complete before termination to avoid a gap in compute availability. Any contractual obligations around notice periods or minimum terms should be reviewed before setting a migration timeline. Some organizations negotiate an exit with Broadcom; others simply let subscriptions lapse and migrate proactively.
