Total Cost of Ownership -- VMware On-Premises vs Azure¶

A detailed TCO comparison of on-premises VMware (pre- and post-Broadcom acquisition), Azure VMware Solution (AVS), and Azure IaaS re-platform for enterprise workloads.

Executive summary¶

The Broadcom acquisition has transformed VMware from a predictable, moderately priced virtualization platform into one of the most expensive infrastructure components in the enterprise stack. This analysis compares four scenarios across 3-year and 5-year horizons:

1. On-prem VMware (pre-Broadcom): the baseline most organizations are migrating from
2. On-prem VMware (post-Broadcom): the new reality after license conversion
3. Azure VMware Solution (AVS): VMware on Azure dedicated infrastructure
4. Azure IaaS re-platform: native Azure VMs replacing VMware entirely

The analysis uses a reference environment of 100 ESXi hosts running 1,500 VMs as the baseline. All figures are illustrative and should be adjusted for your specific environment.

Reference environment¶

1. On-premises VMware costs -- pre-Broadcom baseline¶

This represents the cost structure most organizations had before November 2023.

Licensing (perpetual + SnS)¶

Many organizations purchased perpetual licenses for vSphere and vCenter years ago. The annual cost shown is Support and Subscription (SnS) renewal only. Organizations that purchased NSX, vSAN, and Aria separately paid additional perpetual license fees that are now sunk costs.

Infrastructure costs¶

Operations costs¶

Pre-Broadcom annual total: $5,586,625¶

2. On-premises VMware costs -- post-Broadcom¶

Broadcom's changes affect this baseline dramatically.

New licensing model¶

Cost impact analysis¶

The table above understates the impact for many organizations. The most affected customers are those who:

- Previously licensed only vSphere and vCenter (low SnS) but now must buy VVF or VCF bundles
- Had per-incident or basic support and now face mandatory premium support tiers
- Used perpetual licenses with low SnS rates that are being forcibly converted to subscription
- Negotiated special pricing that Broadcom is not honoring at renewal

For these customers, the licensing line item alone can increase 3x--12x.

Hidden costs in the post-Broadcom era¶

3. Azure VMware Solution (AVS) costs¶

AVS provides VMware vSphere, vCenter, NSX, vSAN, and HCX on dedicated Azure bare-metal infrastructure. All VMware licenses are included.

AVS host pricing¶

Azure pricing varies by region, reservation commitment, and enterprise agreement. Use the Azure Pricing Calculator for current pricing.

AVS sizing for reference environment¶

The reference environment (100 on-prem hosts, 1,500 VMs) typically consolidates to fewer AVS hosts due to higher per-host density and elimination of spare capacity requirements:

AVS included services (no additional VMware license cost)¶

• vSphere Enterprise Plus
• vCenter Server
• NSX-T Advanced (Data Center)
• vSAN Enterprise
• HCX Enterprise (migration tool)
• VMware lifecycle management (Microsoft-managed patching)

AVS additional Azure costs¶

AVS total annual cost (optimized sizing)¶

4. Azure IaaS re-platform costs¶

Re-platforming eliminates VMware entirely. VMs are converted to Azure-native VMs via Azure Migrate.

Azure VM sizing for reference environment¶

Savings with Reserved Instances¶

Storage costs¶

Networking costs¶

Azure IaaS total annual cost (3-year reserved)¶

5. Three-year TCO comparison¶

6. Five-year TCO comparison¶

The 5-year on-prem projections include a hardware refresh in year 4 ($1.5M capital). AVS and Azure IaaS have no hardware refresh costs.

  4     $23,846,500    $26,760,000     $23,455,200  $9,314,720

7. Hidden costs comparison¶

Costs frequently missed in TCO analyses:

8. Cost optimization strategies¶

AVS cost optimization¶

• Right-size clusters: start with minimum nodes, scale based on actual utilization
• Stretch clusters: use AVS stretch clusters for HA instead of duplicate clusters
• Reserved instances: 1-year and 3-year reservations for AVS hosts reduce costs 20--40%
• Azure Hybrid Benefit: apply existing Windows Server and SQL Server licenses to reduce costs
• Auto-scale: scale AVS clusters up during business hours, down overnight (where workloads allow)

Azure IaaS cost optimization¶

• Reserved Instances: 3-year RIs save up to 55% on compute
• Azure Savings Plan: flexible commitment across VM families, 1-year or 3-year
• Spot VMs: up to 90% savings for fault-tolerant, batch, and dev/test workloads
• Auto-scaling: scale VM Scale Sets based on demand
• Right-sizing: use Azure Advisor to identify oversized VMs
• Dev/test pricing: reduced rates for dev/test subscriptions
• Azure Hybrid Benefit: bring Windows Server and SQL Server licenses (saves up to 40%)
• Burstable VMs (B-series): up to 60% cheaper for low-utilization VMs

CSA-in-a-Box data workload optimization¶

For data workloads modernized via CSA-in-a-Box:

• Fabric capacity autoscale: right-size F-SKU based on actual demand
• Databricks auto-termination: shut down idle clusters automatically
• Direct Lake: zero-copy Power BI analytics eliminates data movement costs
• ADF pipeline optimization: use Mapping Data Flows only for complex transforms; dbt for SQL transforms
• OneLake tiering: hot/cool storage tiers based on access patterns

9. Migration cost considerations¶

10. Federal pricing considerations¶

Azure Government premium¶

Azure Government pricing carries approximately 25% premium over Azure Commercial for most services. This premium covers:

• Dedicated government-only infrastructure
• US-person-only operations staff
• FedRAMP High authorization maintenance
• Additional compliance and audit costs

Broadcom federal pricing¶

Federal VMware pricing under Broadcom is negotiated per-agency through federal enterprise agreements. Reported impacts:

• DoD-wide VMware enterprise agreements are under renegotiation with significant increases
• Civilian agencies report 2x--4x increases at renewal
• Some agencies are exploring inter-agency purchasing vehicles to leverage collective bargaining

Cost comparison for federal (Azure Government pricing)¶

AVS in Azure Government is more expensive than on-prem VMware when the on-prem hardware is already paid for. The value proposition for AVS in Gov is elimination of datacenter costs, operational burden reduction, and compliance simplification -- not raw compute cost savings. For pure cost savings in Gov, Azure IaaS re-platform is the stronger option.

11. Broadcom contract negotiation during migration¶

If you are in the process of migrating but your Broadcom contract is up for renewal:

1. Negotiate short-term extensions (6--12 months) rather than multi-year renewals
2. Request per-CPU pricing rather than bundled pricing if you only need vSphere
3. Leverage Azure migration commitment as negotiating leverage -- Broadcom is more flexible when they know you are leaving
4. Document all pricing changes for internal budget justification and audit trail
5. Engage procurement early -- Broadcom negotiations are slower post-acquisition
6. Consider interim AVS -- move critical workloads to AVS immediately to reduce on-prem license footprint
