Enterprise virtualization is going through a rethink, and it grew obvious after Broadcom’s acquisition of VMware. Pricing and licensing changes have pushed many organizations to look at alternatives, though that doesn’t mean they’re dropping VMware overnight. Proxmox VE keeps showing up among the options for building private-cloud virtualization, especially for companies that want to take back control of cost, hardware, and data.
VMware alternatives in 30 seconds
- A CloudBolt study says about 90% of the organizations surveyed are looking at alternatives to VMware.
- More than half report license increases above 25%, though it varies with contracts and configurations.
- Replacing the hypervisor moves slower than the wish to switch, because it touches a critical layer.
- Proxmox VE combines virtualization, high availability, and distributed storage with Ceph, plus backup integration.
- Gradual migrations and proof-of-concept tests let you check performance, compatibility, and operations before production.
There is an apparent contradiction here. Plenty of willingness to consider other platforms, but migration isn’t happening as fast as the interest suggests.
The reason sits in the nature of virtualization. Switching platforms isn’t like swapping out a business application. The hypervisor lives under servers, databases, applications, storage systems, and services that may have run for years.
So for many organizations the question has moved on. It is no longer just which product can replace VMware, but how to make the move without taking on more operational risk than the problem they’re trying to fix.
Why leaving VMware can take months or years
Changing providers can touch cluster design, storage, virtual networks, backups, disaster recovery, monitoring, and internal procedures.
Then there is the knowledge built up in the technical teams. A company that has run VMware for ten years doesn’t just have virtual machines on it; it has procedures, automation, tools, and people used to running it.
A migration has to account for all of that.
That’s why some companies renew their contracts while they look around, and others move certain services first and keep VMware for the more critical workloads for now.
This coexistence phase draws less attention than a full migration, but it lowers the risk.
The CloudBolt study captures exactly that gap between wanting an alternative and being ready to pull it off. Cost pressure can start the process, but the final call usually comes down to technical and operational factors.
Proxmox VE is gaining ground for private cloud
One platform riding this shift is Proxmox Virtual Environment (Proxmox VE), an open-source virtualization solution that runs virtual machines through KVM and Linux containers through LXC.
Its model appeals most to organizations that want to run private cloud on dedicated infrastructure without tying themselves to the commercial terms of the big virtualization vendors.
Proxmox VE can build multi-node clusters, migrate virtual machines, and set up high availability. Pair it with Ceph, the open-source distributed storage system, and you can spread data across many servers.
That lets you design hyperconverged setups where compute and storage share the same cluster, though Ceph isn’t required. Proxmox can also use external storage over various technologies and protocols.
The right architecture depends on the size of the environment, performance needs, redundancy, and each organization’s recovery goals.
For backups there is Proxmox Backup Server, built specifically to work with Proxmox VE. Third-party tools support the platform too.
That growing ecosystem matters, because one of the old obstacles to replacing VMware was never just the hypervisor. Companies need mature tools for backup, monitoring, automation, and recovery around it.
A proof of concept before touching production
Rising costs can push organizations to move faster, but rushing a critical platform swap can turn a money problem into an operations problem.
A safer path usually starts with an inventory of the current VMware environment.
Before you pick an architecture, you want to know how many virtual machines you have, what they consume, what storage they use, how their networks are set up, and what they depend on.
You also need to flag the workloads that need high availability and set RPO (Recovery Point Objective) and RTO (Recovery Time Objective) targets for critical services.
With that in hand, you can build a proof of concept (PoC).
The test should do more than confirm a VM boots on Proxmox. Use it to measure storage and network performance, simulate a node failure, test restores from backup, and see how the cluster handles different incidents.
It also helps train the team that will run the platform later.
The next step can be migrating lower-risk workloads before the critical applications. VMware and Proxmox can run side by side for a while as you validate the new setup.
This approach has another benefit: it separates the technology decision from the commercial deadline.
An organization might decide Proxmox fits all of its infrastructure, only some services, or that VMware needs to stay for now. There is no single architecture that fits every company.
Where the infrastructure lives matters too. A private cloud on dedicated servers in data centers in Spain or elsewhere in Europe lets you decide where data physically sits and who runs each layer.
That control can weigh heavily for European organizations worried about data sovereignty, predictable costs, or vendor lock-in.
The situation around VMware has pushed many companies to revisit infrastructure choices they’d put off for years. Proxmox VE comes up often in that review, but the real shift is elsewhere: organizations are rethinking who controls their virtualization platform, what it costs to run, and how much freedom they’ll have to change it in five or ten years.
Frequently Asked Questions
Can Proxmox VE replace VMware in a company?
It can in many cases, but whether it works depends on your existing applications, storage, networks, backups, and availability needs. A proof of concept is wise before migrating critical workloads.
Is Proxmox VE suitable for high availability?
Yes. Proxmox VE can create clusters and configure high availability for virtual machines and containers, as long as the infrastructure is designed properly.
Does Proxmox require Ceph?
No. Ceph is one storage option among several, handy for certain distributed and hyperconverged setups, but Proxmox VE supports plenty of other storage solutions.
Should you migrate all VMware virtual machines at once?
Not necessarily. A gradual migration lets you test less critical workloads first, validate performance, backups, and recovery, and cut risk before moving critical services.
