DECIDE CLEARLY.
CHANGE SAFELY.
VMware was never the problem.
Predictability has become one.
vSphere is a technically mature platform, and that has not changed. What has changed is the licensing model, the prices and the way customers and partners are treated. Whoever renews today is not deciding about three years, but about the next surprise. We make the exit decision solid: with facts, a fixed-price assessment and a path on which your day-to-day keeps running.
What has actually changed
since the takeover.
Five changes that affect your numbers. Each one on its own is bearable. Together they form a pattern: the terms change faster than infrastructure gets planned.
Infrastructure is planned over ten years.
Not over the next price list.
The decision about your hypervisor comes round every five to ten years. It deserves a basis that lasts longer than one renewal cycle, and a partner who will also advise against the move when staying is the better answer.
Proxmox VE does not stand alone.
It stands on Debian and KVM.
The question put to every open-source proposal is: how long will that carry? With Proxmox VE the answer is not a bet on one vendor. It is the sum of two foundations that have carried for decades.
Debian GNU/Linux
Proxmox VE is built on Debian, one of the oldest and most stable Linux systems, carried by a worldwide community rather than a corporation. No change of ownership can take that base off the market: the source is free, and the license guarantees it permanently.
Since 1993 · freely licensed · independent of any corporationKVM in the Linux kernel
The hypervisor under Proxmox is KVM, a fixed part of the Linux kernel and the most widely used virtualization technology there is. The same technology carries the large public clouds and millions of production servers. A hypervisor does not get more mature than that.
In the Linux kernel · carries hyperscalers worldwideOpen source, without counting cores
Fully open source under the AGPL. No per-core license and no minimum socket count. The subscription pays for the enterprise repository and vendor support, not for the right to virtualize.
High availability built in
Live migration, software-defined storage with ZFS or Ceph and integrated backup are part of the platform, not a bundle surcharge.
Developed in Austria
Proxmox Server Solutions GmbH has been developing in Vienna since 2005, with enterprise support and a partner model that has been stable for years. We are an official reseller partner.
The exit is a transition.
And a transition is our craft.
Six phases, commissioned phase by phase. Your VMware environment carries on unchanged until the new one demonstrably holds, with a way back at every cutover.
What you have, where you stand on licensing, which options are realistic and what follows from them. At a fixed price, even if the result is not to move.
Cluster design, storage concept with ZFS or Ceph, network, backup and restart. Sized for your availability targets.
The target environment is built, a proof of concept runs with your critical systems, load test and failover evidence before the first migration.
Your systems move in planned waves, the uncritical ones first. Each wave is signed off by the application owner before the next one starts.
The cutover follows a script with a defined way back. The point of no return is set deliberately, never suffered.
Support until the agreed sign-off, plus documentation, a recovery manual and training. After that your team takes over, or we do.
When we advise against the exit.
A recommendation only carries weight if the opposite is possible. In these situations we regularly advise postponing the move or leaving it, and we write that into the assessment.
Hard product ties
Applications whose support or certification is explicitly tied to vSphere, for instance in business applications or vendor-bound production IT. Undo the tie first, then move.
Special features in use
Anyone deep into vendor-specific features such as NSX or SRM needs an architecture answer first, not a migration tool. We check that honestly, feature by feature.
Contracts just renewed
Anyone who has just signed for three years migrates without commercial pressure. Then the rule is to prepare rather than rush. Assessment now, move at the end of the contract.
Let's run the numbers on your situation.
The VMware Exit Assessment gives you an inventory, the options and the costs over the lifecycle. As a paper that stands up in front of your management. At a fixed price, with a clear scope.
