Why are companies migrating away from VMware?
Broadcom's $69 billion acquisition of VMware has fundamentally changed the economics and relationship for VMware customers. 98% of VMware customers are now evaluating alternatives.
150%+ Average Price Increase
VMware licensing costs surged 150% on average under Broadcom, with extreme cases reaching 1,500%. Perpetual licenses eliminated — subscription-only model enforced.
Forced Bundling (72-core minimum)
Minimum purchase raised from 16 to 72 cores. Standalone products (ESXi, vSAN, NSX) discontinued. Customers forced to buy bundles they don't need.
Partner Program Terminated
Broadcom ended VCSP Advantage Partner Program (October 2025). VMware Cloud on AWS end-of-sale in 2025. Smaller customers deprioritized.
Vendor Lock-In Risk Escalated
Single-vendor dependency on Broadcom with unpredictable pricing trajectory. No perpetual license fallback. Migration becomes more urgent each renewal cycle.
Reduced Innovation & Support
Post-acquisition workforce reductions. Slower product updates. Support quality declining according to customer reports across forums and surveys.
Open Source Momentum
OpenStack powers 45M+ cores globally. OpenInfra Foundation launched VMware Migration Working Group. Dedicated migration tools now mature and production-ready.
