If your work touches virtualisation and you are weighing what to learn next, most of the advice going round amounts to “learn the new thing”. There is a published calendar that says something more specific.
Nineteen Commonwealth contracts with VMware, worth A$485.3 million, expire across 2027 and 2028. Broadcom, which bought VMware, has repriced it, and those buyers are weighing whether to renew or leave. The obvious advice is to learn whichever platform they move to. Having gone through the register, the alternatives, and what one of these programmes looks like from inside, I think that is the wrong lesson.
These are Commonwealth contracts because those are the ones published. The same repricing reaches banks, insurers and large private employers, whose contracts are not public — so what follows is the part of the market that can be counted, not the whole of it. The skills question does not change with the sector.
If this is not your field: virtualisation software lets one physical server run many separate computers. VMware has been the default for twenty years, so a large organisation may run thousands of systems on it. Leaving means moving every one of them.
When the contracts land
Most of the value expires in 2028
Published value of Commonwealth VMware contracts, by year of expiry
19 contracts, 11 agencies. Contract end dates, not a schedule of work.
The largest is the Department of Defence: A$178.1 million, to 11 December 2028. The sequence there is not the one you would guess.
Defence was reportedly told to reduce its VMware use under a “mandate” issued around September 2025 — and then, months later, signed the A$178.1 million renewal. iTnews reported this on 30 October 2026, noting the formality of the mandate is unclear and that Defence declined to comment on its scope. Cost is understood not to be the only driver; sovereignty is also a concern.
If the reported mandate reflects Defence’s direction, the intention to reduce VMware use came before the renewal rather than after it. Read that way the contract is runway rather than reversal — you keep paying for what you are still running while you move off it — and it says something about pace: a department that had decided to move signed for three more years.
The platform is not the hard part
Every credible alternative ends the VMware subscription. Nutanix bundles the software with its own platform licence, Microsoft includes it in Windows Server licensing, Proxmox is free to run, Red Hat includes it in an OpenShift subscription.
They are not interchangeable. Each replaces a VMware bill with a different bill, and the storage, networking, backup and support requirements differ with it. Ending one subscription is not the same as ending the cost.
All four also ship first-party tools for moving existing systems across — Nutanix Move, Red Hat’s Migration Toolkit, Proxmox’s importer, and from Microsoft both a long-standing capability in System Center and a free Windows Admin Center extension now in public preview. They differ in maturity, batch size, and whether the tool itself costs anything. The full comparison is here.
What none of them does is make the move easy. From the reporting on Defence, by someone inside it:
“They’ve spent their entire careers with one style of design and we’ve now made them shift and it’s been quite a challenge. [It’s been about] the training, the experience and making people understand why we’re going through this change — [that] it’s not change for change’s sake.”
That is the constraint as described from inside the largest of these contracts. Not the licence, not the tooling. The same report notes why: the software is embedded in IT operations, and for many administrators it is an ecosystem they know better than any alternative.
At that scale, moving means working out what depends on what, rebuilding backup and recovery around the new platform, re-certifying secure environments, retraining operators, and running old and new side by side until the switchover is safe. A conversion tool moves a system. It does not tell you what order to move things in, what will break, or how to get back if it does.
None of that is bought in a licence. It is bought in people.
Which is why the hiring figures read oddly
The alternatives are barely advertised yet
Advertised Australian roles naming each platform, 2 November 2026
Nutanix plus Proxmox = 9.6% of VMware roles. The forecast below turns on that ratio.
The obvious reading is that VMware is in decline and its skills are a liability. Against the contract calendar, that is at best incomplete.
VMware expertise stays relevant whether an organisation renews or leaves. A large installed base needs people to run it, and a move needs people who understand what is being replaced. The counts cannot tell you how much of the demand is which, and anyone citing them owes you the reading they mean.
One more thing they cannot tell you cleanly, and it is why the forecast below counts only Nutanix and Proxmox. Taken together, the three alternatives account for 125 advertised roles against VMware’s 239 — a bit over half, which sounds like a market that has already arrived. But Hyper-V is most of that, and Windows shops were running Hyper-V long before Broadcom repriced anything, so its count says more about the installed Microsoft estate than about anyone leaving VMware. Nutanix and Proxmox start from much smaller numbers, so their relative growth is a more focused signal — though still an indirect one, since those counts also carry ordinary operational hiring for installations that already exist.
So, what would I learn
You can get hands-on with each alternative in weeks, so a certificate in one is worth less than it looks — though being trusted with production takes considerably longer. What is scarce is the ability to move a large estate safely: a different skill, and a slower one to acquire.
Learn migration engineering rather than a platform badge. The work listed above — sequencing, dependencies, switchover and the way back — is what every one of these programmes needs, whichever destination wins. Conversion tooling is one part of it, not the whole.
Keep your VMware depth, and say so. On a CV, “moved N systems across, including the ones that would not go” beats any certificate. The failures are where the judgement shows, and the people reading your CV know it.
Add one alternative, picked from what the organisations you want to work for already run. On the figures above, Hyper-V is advertised about seven times as often as Nutanix, so for most readers it will be the one within reach.
Spend nothing yet. Hyper-V ships in Windows Pro and Windows Server, Proxmox is free, Nutanix has a free edition. Build something small on hardware you own and move a real system onto it — then move one that does not go cleanly. A certificate is worth something after you can do the thing.
And if you are deciding a renewal rather than preparing for one, the same finding points the other way: the threat to leave is only as good as your ability to carry it out, which is a question about people and months rather than products. Worth knowing too that the cheapest responses are not moves at all — an entitlement audit, or third-party support, can cut the bill without touching the platform.
What would make this wrong
Broadcom could discount materially on renewals in this region. If the price pressure goes, so does the wave.
The work might not be hired locally. If it goes to offshore delivery centres and global integrators rather than Australian hiring, the role counts stay flat however much money expires. I think this is the likelier of the two, and it is why I would weight migration skills — which travel — over platform badges, which do not.
And the honest limit. A contract register records what was bought and when, never intent. Nothing here establishes that any agency will leave — only what each committed to, and until when. The Defence reporting rests on unnamed sources and a department that declined to comment.
Forecast
A prediction that cannot be settled objectively is not worth making, so here is the rule alongside the call.
Advertised Australian roles naming Nutanix or Proxmox, as a share of advertised roles naming VMware, will exceed 15% — up from 9.6% at this measurement. Confidence: 40%. Resolves: 29 July 2028, on a single measurement taken that day by re-running the same four exact-phrase searches on the same job board, with the counts and the search URLs published alongside the result.
The resolution date is arithmetic: the last 2027 contract expires 29 July 2027, and a twelve-month window for hiring to become visible runs to 29 July 2028.
Below even odds deliberately: I think this work is more likely to be delivered by teams Australia does not advertise for. It is also a narrow instrument — one job board’s advertised counts, not migration activity. If that board materially changes its search coverage, query handling or how it counts results before 2028, I will document the change and may record the forecast as inconclusive rather than settle it on a measurement that is no longer comparable.
One thing I cannot answer
If the alternatives all end the licence cost, and the capacity to move is the scarce thing, then the rational move for a large buyer is to secure that capacity rather than to choose a platform. In the records I searched I did not find it — no panel, no framework, no advertised programme. Either buyers do not see it that way, or they are doing it through channels that leave no public record. I would like to know which.
