Broadcom VMware Alternatives
A UK exit plan with 3-year TCO numbers
Looking for VMware alternatives after Broadcom? You are not alone — UK SMEs and mid-market organisations are reporting renewal quotes 3–5x previous spend. We compare Proxmox VE, Microsoft Hyper-V, Nutanix AHV and Azure VMware Solution against your specific renewal, with a written 7-day advisory and staged migration if you decide to move. Typical 3-year TCO reduction: 30–60%.
No upsell on the initial enquiry — send your renewal quote and we tell you whether to migrate or renegotiate.
Why this conversation got urgent
Subscription-only licensing has compressed product choice. Per-core minimums on VCF/VVF push UK renewals 3-5x previous spend.
Perpetual licences ended. Existing perpetual customers can stay on support only by moving to subscription.
Smaller VMware partners (LARs, MSPs) have been re-tiered or removed from the channel — reducing negotiation leverage on renewal.
Renewals that used to be a back-office formality now require a board-level TCO review with a costed alternative on the table.
Cyber-insurance and procurement audits increasingly ask about platform-vendor concentration risk and the existence of an exit plan.
The 30 January 2025 ECCTA UK identity-verification changes and 17 October 2024 NIS2 transposition both touched supplier-due-diligence narratives — concentration risk is now a regulator question.
Your realistic alternatives
None of these are drop-in replacements. Each has a different cost shape, operating model and skill profile. We compare three for you in the advisory.
Proxmox VE
Best fit: Cost-sensitive on-prem, KVM-based
Pros: Free core, large community, ZFS + Ceph storage built-in, low licensing exposure
Watch-outs: Smaller ecosystem than VMware; staff retraining required (~2-4 weeks)
Licensing model: Free core; optional support sub from ~€110 / CPU socket / year
Best for: 20-200 VMs
Microsoft Hyper-V
Best fit: Microsoft-heavy estates already running Windows Server Datacenter
Pros: Bundled with Windows Server licences (zero marginal cost), familiar to MS admins, SCVMM management
Watch-outs: Less mature for non-Windows guest workloads; some advanced features lag VMware
Licensing model: Included with Windows Server (Standard or Datacenter editions)
Best for: 20-500 VMs (mostly Windows guests)
Nutanix AHV
Best fit: HCI-style consolidation, mid-market, integrated platform
Pros: No separate hypervisor licence on Nutanix nodes, integrated management plane, strong DR
Watch-outs: Hardware lock-in to Nutanix-certified nodes, higher up-front cost than commodity x86
Licensing model: Bundled with Nutanix node licences (per-node)
Best for: 50-1,000 VMs
Azure VMware Solution / Public Cloud
Best fit: Workloads suitable for cloud, variable demand, regulated workloads with sovereignty options
Pros: Removes hypervisor licensing entirely (op-ex), elasticity, pairs with Azure Arc
Watch-outs: Egress costs, network re-architecture, sovereignty review, cost variance month-to-month
Licensing model: Pay-as-you-go (AVS hourly) or 1/3-year reserved instances
Best for: Variable — workload-by-workload assessment

How an SBH-led migration runs
- 1
Discovery (2-4 weeks)
VM inventory, dependency map, performance baseline, current licensing position, target audit/compliance posture. Output: discovery report and inventory spreadsheet.
- 2
Target selection (within advisory)
Three-year TCO across two or three target platforms scored against your change windows, skill profile and audit posture. Output: written recommendation with explicit reasoning.
- 3
Pilot (2-3 weeks)
Non-prod workload migrated to the chosen target. Runbooks proven; rollback rehearsed; performance baseline validated against VMware. Output: signed-off pilot.
- 4
Staged cut-over (4-9 weeks)
Production tiers moved on agreed change windows. Backups and DR validated each batch before proceeding. Output: cut-over completion record per batch.
- 5
Post-cut-over assurance
Performance, cost, and security posture verified. Cyber Essentials / CE+ / ISO 27001 evidence updated. Operational handover and runbooks for your IT team. Output: handover pack.
What we cover beyond the hypervisor
Cybersecurity posture
Migration is a change-window opportunity. Existing Cyber Essentials/CE+ findings (unsupported OS guests, weak MFA on mgmt, flat networks) close at the same time as the platform change.
Audit trail and compliance
Hypervisor changes touch ISO 27001 A.8.13/A.8.14 (continuity), NIS2 Article 21(2)(c). We document before/after evidence for the audit pack.
Change-window discipline
Staged batches with backup + DR verified before the next batch. Rollback rehearsed before the first production cut-over. No big-bang migrations.
Operational handover
Runbooks for the target platform, training for your existing IT team, BAU operating model defined before we leave.
How to engage
Two engagement tiers. Most UK businesses start with the advisory and decide on the migration only after the written recommendation.

Frequently asked questions
Why are UK businesses leaving VMware in 2026?
Following the Broadcom acquisition of VMware (close November 2023), the simplification of the product portfolio, the elimination of perpetual licences, and the shift to per-core subscription bundles (VCF, VVF) have materially raised total cost of ownership for most UK SMEs and mid-market estates. UK customers have widely reported renewal quotes 3-5x previous spend; some workloads attract 5-7x. Smaller VMware partners (LARs, MSPs) have also been re-tiered or removed from the channel, reducing negotiation leverage. Renewals that used to be a back-office formality now require a board-level TCO review.
My renewal is in 90 days — what should I do first?
Three things in parallel: (1) get the formal Broadcom renewal quote in writing and read the exact bundle composition; (2) commission a 7-day Migration Advisory engagement to compare three costed alternatives against the renewal — Proxmox, Hyper-V, and either Nutanix or Azure VMware Solution depending on your skills mix; (3) put a temporary 1-year extension request to Broadcom in writing in case you need the time. Most renewals can be paused 30 days, but only if you ask before the deadline.
Do I have to move everything at once?
No. Most migrations are staged: low-risk workloads first (dev, test, internal apps), then production tiers, with the most regulated systems last. Hybrid configurations (some VMware, some target hypervisor or cloud) are common during the cut-over window. We typically run 2-week production batches with backup and DR validated before the next batch.
What is the typical UK SME timeline?
For a 50-200 VM estate, scoping plus migration usually runs 8-16 weeks. Discovery and dependency mapping take 2-4 weeks; pilot migration 2-3 weeks; staged production cut-over 4-9 weeks depending on change-window cadence and storage size. For smaller estates (under 30 VMs), end-to-end is closer to 4-6 weeks. For larger estates with strict change windows or regulated workloads, 16-26 weeks is realistic.
How does this affect my Cyber Essentials, NIS2 or ISO 27001 posture?
Hypervisor changes touch firewall, secure configuration, patching, and often backup. Treat the migration as a controlled change with documented before/after evidence. Done well, a migration is also a chance to close legacy CE/CE+ findings (unsupported OS guests, missing MFA on management interfaces, weak segmentation) — we factor this into the migration plan from day one. NIS2 essential entities should also document the change in their risk register and update the supply-chain assurance file for any downstream customers asking.
Can SummitBridge Horizon execute the migration or only plan it?
Both. We scope, plan, and run the technical execution end-to-end for UK businesses, or partner with your internal team and existing MSP. Typical engagements include discovery + roadmap (advisory, £1,500), pilot, migration, and post-cut-over assurance (full service, from £3,500). We work alongside your existing IT team rather than replace them.
What about Broadcom's VCF / VVF bundles — can I just stay?
Staying is a valid option, especially for estates already on a multi-year ELA, with vSAN dependencies, or with strict change-aversion. We provide a renewal review that compares the renewed VMware quote against the realistic 3-year TCO of two or three alternatives — so the decision is fact-based rather than forced. Roughly 1 in 4 of our advisory engagements concludes "renew, but renegotiate the bundle composition" rather than migrate. The advisory pays for itself either way.
What about the AVS (Azure VMware Solution) middle path?
AVS lets you keep your VMware skills, runbooks and operational model while shifting commercial risk from Broadcom to Microsoft. It is genuinely a middle path for organisations with vSphere/vCenter operational maturity that do not want to retrain teams. Costs are workload-dependent and AVS RIs (1 or 3 year) are typically required to make the maths work. We model AVS alongside Proxmox/Hyper-V/Nutanix in the advisory.
Do you have Proxmox and Hyper-V engineering depth, or only consultancy?
Our SBH TechOps capability covers production experience on Proxmox VE, Hyper-V (with SCVMM), Nutanix AHV, and Azure VMware Solution. Advisory and migration execution are delivered through the SBH TechOps function (40 AI agents + 4 lobes orchestrating implementation), with named senior consultants supervising the engagement. We do not subcontract the technical work to undisclosed third parties.
What does the 7-day advisory deliverable actually look like?
A 12-20 page written report covering: discovery summary (VM inventory, dependencies, current licensing), three costed alternatives with 3-year TCO and operating model implications, a risk matrix (cybersecurity, compliance, change windows, rollback), a recommended path with explicit reasoning, and a phased implementation plan with effort estimates. The deliverable goes to a board or steering group; it is decision-grade, not a marketing artefact.
