VMware Licensing Change Azure 2026: UK Cost Impact

Azure closes the BYOL loophole

Microsoft has confirmed it will stop selling the license-included version of Azure VMware Solution (AVS) from 31 October 2026, with existing customers required to bring their own Broadcom VCF licences and shift to a new Azure arrangement by 30 August 2027, according to The Register. Microsoft's own advisory tells customers to "allow plenty of time to purchase VCF licenses from Broadcom and complete the transition to AVS VCF BYOL", warning that current deployments will stop working once the window closes.

This matters because AVS bundled vCenter, vSAN, vSphere and NSX with the licences included, sparing customers a separate Broadcom purchasing relationship entirely. Broadcom's licensing rules now bar hyperscale partners from selling VMware licences at all, so Microsoft — like other cloud providers before it — has no choice but to push customers into buying VCF directly from Broadcom and carrying it to Azure themselves.

Why UK procurement teams should care now

For UK IT and procurement leads, this removes a genuinely useful hedge: a way to keep VMware workloads running in Azure without signing up to Broadcom's full-fat Cloud Foundation commercial terms. From next year, every AVS customer becomes a direct Broadcom licensing customer, with all the three-year subscription commitments, currency exposure on USD-denominated MSRP pricing, and renewal negotiation risk that implies.

Teams that assumed AVS was a stable, lower-friction VMware-on-Azure option should treat this as a trigger to reassess total cost of ownership immediately, not at renewal time. It's worth using a dedicated exercise to assess your Microsoft VMware licensing costs against BYOL VCF pricing before the October 2026 sales cut-off narrows your negotiating options.

What the VCF bundle actually costs

Broadcom's published packaging gives a sense of scale. vSphere Standard lists at $50 per core, vSphere Foundation at $135 per core, and the full VMware Cloud Foundation bundle at $350 per core MSRP, per Veeam's breakdown of the current tiers. VCF bundles in vSphere Enterprise Plus, vSAN Enterprise, Aria Suite Enterprise, NSX Networking, HCX Enterprise and SDDC Manager — most of which small and mid-sized UK sites never asked for and won't fully use.

Even the entry-level Essentials Plus Kit, sold as a 96-core package, comes in at $10,080 for a three-year term, while a modest two-host, 16-core-per-host deployment can run to $12,960 for vSphere Foundation or $19,440 once a three-host, three-year configuration is priced. It's worth taking the time to compare vSphere Foundation and Cloud Foundation bundles against your actual workload footprint before assuming you need the top tier.

Tesco's bill is the UK's cautionary tale

UK buyers don't need to speculate about worst-case outcomes — Tesco has already lived one. The retailer said one April 2026 quote for a year of VMware Cloud Foundation 9.0 plus mainframe software and support came to $23.5 million, roughly a 175% increase on what it believed it was entitled to under its 2021 agreement. Tesco also said Broadcom stopped supporting its virtualization software in January 2026, forcing it to pay for third-party support mid-transition.

The result is one of the largest live VMware exits in the UK market: Tesco is reportedly moving around 40,000 server workloads off VMware entirely. Whatever your organisation's size, the pattern — steep renewal increases layered onto support withdrawal — is the exact risk this Azure change now pushes AVS customers toward if they don't plan ahead. Running the numbers through a calculate your VMware migration costs exercise now is considerably cheaper than discovering them in a renewal quote.

Hypervisor alternatives worth evaluating

Broadcom has been candid that it isn't overly concerned about smaller customers leaving for other virtualization vendors — its strategy is built around large accounts committing to VCF. That leaves the door open for UK buyers to genuinely shop around. Options in active circulation include Microsoft's own Hyper-V stack, Azure Stack HCI for hybrid on-premises workloads, and open alternatives such as Proxmox, which has recently extended its own platform support.

Broadcom's decision not to renew VMware Cloud Service Provider contracts after 26 January 2026 has already forced some smaller hosting customers to migrate platforms once before, so this isn't the first disruption many teams have absorbed. It's a good moment to explore alternative hypervisor solutions and plan your VMware migration path with a phased approach rather than a rushed cutover, and to weigh whether consider migrating to Azure Stack HCI fits your hybrid requirements better than staying on Broadcom's roadmap.

Refreshing hardware alongside the licence decision

A hypervisor migration is rarely just a software decision — it's usually the point at which UK buyers also reassess ageing server estates that were sized around VMware's old licensing model. If you're moving workloads to a new hypervisor or rebuilding a cluster for Azure Stack HCI, it's worth reviewing your server configuration requirements at the same time, whether that means specifying through the Dell server configurator, the HPE server configurator, or the Lenovo server configurator to match new core-density and licensing-per-core realities.
