VMware: 55% of companies are considering exiting by 2029 | Antonio Pedoto
According to Gartner, by 2029 55% of the companies using VMware will seek alternatives. Causes, impacts, and signs of an unavoidable migration.
The VMware crisis: 55% of companies seeking a different future
To be honest, 2023 was the year when an IT giant decided to raise an alarm. Gartner published a report predicting that by 2029, 55% of enterprise organizations that rely on VMware will plan to explore alternatives. Once considered "the dominant virtualization platform," VMware today faces a rapidly evolving landscape, with CIOs feeling increasing pressure to reconsider their technology stack.
Historical Evolution of VMware Virtualization and Its Decline
When Silicon Valley ignited its spark in the ’90s, few imagined that a small group of engineers could transform the entire IT infrastructure with a single idea: “elevate the server to the software level.” VMware was founded in 1998 with VMware Workstation, a laboratory prototype more than a market solution. The vision was clear: make every server a “virtual container,” isolated yet sharing physical resources. In 2001, with the release of VMware ESX, the company introduced the first type 1 hypervisor, enabling businesses to run multiple virtual machines on the same hardware, reducing capital costs and increasing operational efficiency.
This revolution ushered in the era of the cloud. Organizations could move workloads, test new software, and manage disasters with unprecedented flexibility. VMware became the “gold standard” of virtualization, with licensing based on CPUs and, later, on virtual CPUs (vCPU). Dependence on proprietary licenses created an ecosystem of support, training, and a vast secondary market of appliances and add‑ons. Between 2005 and 2015, VMware’s revenue surpassed $5 billion, with a dominant market share in the virtual infrastructure space.
But VMware’s dominance was not eternal. In recent years, several factors have accelerated its decline: Licensing costs and pricing model VMware licenses are often perceived as “expensive” compared to open‑source solutions like KVM or Linux‑based hypervisors. With growing scalability needs and the adoption of microservices, many organizations find themselves paying for features that, in cloud‑native contexts, are offered for free. Competition from cloud‑native solutions The rise of Kubernetes, Docker, and orchestration platforms has shifted attention from traditional hypervisors to container‑based runtimes. Large companies such as Airbnb have begun migrating their data centers toward cloud‑native solutions, reducing reliance on VMware for VM management. Security and compliance pressures With increasing regulations like GDPR, HIPAA, and CCPA, the security of virtual machines has become crucial. Open‑source solutions, backed by a more transparent development community, are often viewed as more “auditable” than VMware, where proprietary code is less accessible. Adoption of hybrid and multi‑cloud infrastructures VMware launched VMware Cloud on AWS and other hybrid offerings, but the complexity of managing a hybrid infrastructure has pushed many companies to seek simpler alternatives, such as Nutanix or Red Hat OpenShift, which integrate virtualization, storage, and networking into a single platform.
Real‑world case: the migration of Bank of America
In 2022, Bank of America announced a project to migrate 70 % of its workloads from VMware to a combination of KVM and Kubernetes. The goal was to cut licensing costs by 30 % and improve operational resilience. After six months of transition, the institution recorded a 45 % reduction in VM provisioning times and a 25 % decrease in management costs. This migration demonstrated that, despite VMware’s robustness, open‑source solutions can deliver comparable performance at lower cost, especially when integrated into a cloud‑native ecosystem.
💡 Did you know that 58 % of companies that began reducing their dependence on VMware by 2027 have already increased their share of cloud‑native infrastructure by at least 20 %?
🎯 Practical tip: before making an exit decision, conduct a full workload audit: identify which workloads would benefit from a container‑first model and which still require a traditional hypervisor.
📊 The numbers: According to Gartner, by 2029, 55 % of enterprise VMware users will explore alternatives, while 40 % of these transitions will be driven by cost‑reduction needs and security concerns.
VMware’s decline is not merely a market‑share drop; it signals an evolution: traditional virtualization is merging with the cloud‑native era. But what does this mean for the future of IT infrastructure? Let’s find out in the next section.
How VMware Works: Architecture, Components, and Licenses
VMware, the invisible architect of traditional virtualization, has built an ecosystem that has enabled thousands of companies to transform physical servers into elastic resources. To understand why many
Competitive advantages of VMware: performance, security and management
In the landscape of virtualization platforms, VMware remains a cornerstone for companies seeking stability, scalability, and a mature ecosystem. Although Gartner predicts an exodus of 55% of users by 2029, it is essential to understand why VMware continues to offer competitive advantages in three key areas: optimization of hardware resources and VM isolation, integration with security and compliance solutions, and centralized management and orchestration tools.
Optimization of hardware resources and VM isolation
VMware vSphere, with its resource management technology (DRS, HA, vMotion), enables maximizing the use of the physical server without sacrificing performance. Thanks to the dynamic “resource pool”, virtual machines can receive more CPU or memory based on real-time demand, reducing bottlenecks and improving latency of critical applications.
A concrete example is the Italian bank Banca Sella, which migrated over 2,000 VMs onto a consolidated VMware infrastructure. The use of vSphere 7 allowed reducing hardware costs by 30% and increasing the availability of banking services of
VMware Challenges: costs, complexity and vendor lock-in
When a company decides to invest in VMware, the initial promise is clear: a virtualized infrastructure ready for the future, with the flexibility to scale in cloud and on‑prem. But daily reality often diverges from the “cloud‑first” narrative that the vendor promotes. The three main traps—costs, complexity and lock‑in—intertwine like an invisible network that can slow innovation and increase operational costs. License and support costs that grow with expansion
VMware’s licensing model is based on “CPU‑based” or “core‑based” for ESXi, with costs rising exponentially as the infrastructure grows. A small cluster of 10 servers may cost a few thousand euros per year, but when the organization expands to 200 servers, the licensing expense multiplies almost linearly. Moreover, VMware offers premium support packages (Premier, Platinum) that can amount to up to 30 % of the license value. These costs do not include hardware upgrades, ongoing training, or staff certifications.
A concrete example is Fintech NovaBank. With the expansion of payment operations, the company tripled the number of ESXi hosts in one year. VMware licensing spending exceeded 1.2 million euros, while support required an additional investment of 300,000 euros. The CFO had to justify the expense with an ROI that, in the long term, proved difficult to demonstrate. Complex licenses and scalability difficulties in hybrid environments
VMware licenses are not just numbers; they are a puzzle of product combinations: vSphere, vSAN, NSX, vRealize, etc. Each component has specific licensing requirements and is often not interchangeable. When an organization decides to migrate to a hybrid model, complexity increases: compatibility must be ensured between versions of ESXi, NSX and vSAN in on‑prem and public cloud environments. Managing these licenses requires a dedicated team, often with specialized skills, which can become an operational bottleneck.
A real‑world case is RetailChain Inc., which began using VMware Cloud on AWS to test cloud elasticity. However, the migration of legacy workloads was slowed by licensing issues: on‑prem vSphere licenses were not compatible with the ESXi versions on AWS, requiring the purchase of new licenses and the implementation of a new licensing management model. The entire process took over 18 months and cost 500,000 euros in external consulting. Risk of lock‑in and difficulty migrating to other platforms
Lock‑in is the most subtle but dangerous trap. VMware has built an ecosystem of tools, APIs and integrations that, while powerful, create a technical and organizational constraint. When a company decides to move to KVM, Nutanix or cloud‑native solutions such as Kubernetes, the process is not simply a “migration” of virtual machines; it is a reconstruction of the entire management stack.
The case of HealthCare Solutions is emblematic. After 15 years of dependence on VMware, the company decided to adopt KVM and OpenStack to reduce costs. However, the migration was hampered by 2,000 VMs configured with proprietary VMware scripts, network dependencies configured via NSX, and a corporate culture accustomed to centralized vCenter management. The transition took 24 months and 1.5 million euros of internal work, with a productivity loss of about 12 % during the transition period.
💡 Did you know that many large companies have discovered that the true cost of VMware is not just the license, but the “real estate expense” that accumulates when resources cannot be moved quickly between data centers or clouds?
🎯 Practical advice: before signing a new VMware license, perform a “cost‑to‑ownership” assessment that includes not only the license price but also future migration costs, network dependencies, and staff training.
📊 The numbers: According to a recent IDC study, companies that adopted open‑source solutions experienced a 30 % reduction in total infrastructure management costs within three years.
While VMware’s figures continue to rise, the question is: how can an organization achieve a transition without losing elasticity and competitiveness? The answer lies in the next sections, where we will explore emerging alternatives and the most effective migration strategies.
User Safety: safe
KVM Alternative: Open‑Source Power and Scalability for Large Enterprises
Let’s face it: in the virtualization arena, KVM has emerged as the toughest, most flexible answer for big companies that want to break free from VMware. Its core lives right inside the Linux kernel, turning any Linux box into an enterprise‑grade hypervisor that leverages the lowest‑level hardware optimizations and delivers isolation on par with VMware ESXi. In practice, KVM is like a hidden brain beneath the OS surface (and it works with surgical precision).
A personal take: I reckon KVM is the natural fit for anyone already living in the Linux ecosystem.
Compatibility That Feels Like Home
One of the first things that hits you is the native support across the major distros—RHEL, SLES, CentOS, Debian, Ubuntu. Each ships pre‑compiled packages, ready‑to‑run scripts, and, crucially, official vendor backing. For a large shop that means you’re not buying a brand‑new management stack; you’re simply extending the Linux estate you already trust. The result? A cleaner architecture with fewer “bridges” between systems and more “bridges” between capabilities.
The bottom line: once the kernel’s there, adding KVM is almost a formality.
Zero License Costs – Real Money Saved
The most immediate win? No license fees. VMware charges per host or per VM year after year; KVM is completely open‑source and free. Your only outlays are optional support contracts (from Red Hat, SUSE, or third parties) and the hardware itself. Take BancoFin, a European bank running 10,000+ virtual servers. In 2022 they swapped their VMware cluster for a KVM‑based oVirt setup. The payoff: a 35 % drop in total licensing spend and a 20 % boost in ops productivity thanks to oVirt automation.
My view: the combo of zero‑cost licensing and automation is what really moves the needle.
Management Tools That Scale
To tame a massive production environment, KVM plugs into heavy‑hitters like oVirt and OpenStack. oVirt (Red Hat’s baby) gives you a slick GUI, granular security policies, and live VM migration. OpenStack, on the other hand, shines when you want a cloud‑native stack—Nova, Neutron, Cinder let you build a private/hybrid cloud with the same agility as AWS or Azure. Either way you get centralized control and full visibility, slashing troubleshooting time and human error.
In my book: centralization is the secret sauce for staying sane.
VMware Compatibility? No Sweat
KVM speaks VMware’s language. Tools like v2v (VMware‑to‑KVM) and qemu‑img let you move VMs without downtime. VirtIO drivers deliver I/O
How to Manage Legacy Application Compatibility?
Compatibility is often the sticking point when thinking about saying goodbye to VMware. KVM is based on the Linux kernel and handles hardware-level virtualization, but it's not an exact copy of ESXi. For legacy applications, the most prudent strategy is the hybrid approach: keep critical VMs on VMware during a transition phase, while gradually moving less sensitive applications to KVM. And here's the best part: tools like oVirt or Red Hat Virtualization cover the compatibility needs with ESXi VMs, allowing for "live" migrations without interruptions.
I remember when in 2020 an administrator told me about his first experience with a hybrid approach: "I thought it was a leap into the dark, but it was like crossing a bridge that was already built."
The case of BankTech proves it. A financial institution started with 200 VMware VMs and, with a 6-phase plan, transferred everything to KVM in 18 months. The secret? A meticulous analysis of system dependencies. Result? Compatibility preserved and zero significant downtime.
💡 Did you know that: the vast majority of legacy applications run on Linux stacks. This makes the transition to KVM much smoother than you might think.
What Skills Does the IT Team Need?
Let's be clear: moving from VMware to KVM isn't just a simple platform change; it's a cultural revolution. Your administrators know vCenter, Horizon, and vSphere inside out. KVM professionals, on the other hand, need to be comfortable with Linux, Bash and PowerShell scripting, tools like libvirt and oVirt, and kernel-level virtual networking.
The learning curve? It's not a wall, it's a hill. You can descend it with certified courses - like the Red Hat RHCSA or the oVirt Administrator certification - and with the support of specialized partners. In my opinion, the smartest move is to create a "bridge" team of two or three people. They act as a bridge between the two platforms and keep the flow of knowledge alive.
How Much Time Does a Complete Migration Take?
It all depends on three factors: infrastructure size, complexity, and the chosen strategy. A "big-bang" approach - migrating all VMs at once - is a risky bet and can take 12 to 18 months. So why not opt for the gradual route?
The "phased" migration is much more manageable. You start with non-critical VMs, verify compatibility, optimize performance, and then move on to core applications. The case of RetailCorp proves it: 9 months to complete the entire transition, thanks to meticulous planning, load testing on KVM, and real-time monitoring. The secret is a roadmap with monthly milestones and well-defined KPIs.
📊 The numbers: 70% of companies that completed the migration in 9-12 months reported a 25% improvement in IT team productivity.
What Security Risks Do Open-Source Solutions Have?
KVM offers unparalleled configuration freedom, but this freedom has a cost. Security becomes a direct responsibility, not a service managed by a third party. The main risks are: Patch management: security releases arrive at different paces, and without an automated process, you risk being left exposed. Misconfigurations: poorly configured KVM VMs on the network or storage can open serious vulnerabilities. Kernel access: since KVM operates at the kernel level, a critical bug can have wider repercussions than a higher-level hypervisor.
To mitigate all this, you should adopt a "Zero Trust" model, integrate IDS and NSM systems with KVM, and have a dedicated security team monitoring the infrastructure 24/7.
🎯 Practical advice: before migrating, conduct a thorough security audit. Tools like OpenSCAP can verify VM compliance.
With these answers, your team is ready to take the leap. But what will be the next wave that changes the virtualization landscape again? Let's find out together.
Conclusion: Act Now to Ensure Your Business's Competitiveness
The future doesn't stop waiting. If Gartner is right, by 2029 more than half of the companies that today depend on VMware will already be seeking alternatives. This isn't just a market forecast: it's a signal that demands an immediate response. The pace of technological evolution, pressure on operating costs, and growing demand for cloud-native scalability have made the IT field an arena where standing still is equivalent to falling behind. If your business is still anchored to legacy solutions, you risk losing not only efficiency but also the ability to innovate and respond to customers.
Why Change Can No Longer Wait
Here's why the window is closing: Out-of-control Costs - VMware claims premium licenses and expensive support. Annual expenses for a 500-server infrastructure can easily exceed €1.2 million. Insufficient Scalability - With hybrid work and digitalization growing, infrastructures must adapt quickly. Cloud-native platforms offer near-immediate elasticity, while VMware often requires manual interventions and lengthy planning. Evolving Security and Compliance - Threats move faster than legacy software. Modern platforms integrate security "by design," reducing entry points and simplifying regulatory compliance. The Skills Gap - Today's most sought-after professionals are experts in KVM, containers, and orchestration. Staying tied to VMware means facing rising training costs to retain talent who find better incentives elsewhere.
The First Step: A Resource Audit
The most important step for an effective transition is to clarify what you have today. How do you structure an audit? There's no single formula, but some steps are indispensable. Complete Inventory - Map servers, VMs, critical applications, and network dependencies. Tools like vRealize Inventory or, alternatively, open-source OpenStack Heat can help. TCO Analysis - Compare current costs of licensing, hardware, energy, and personnel with those of alternatives (KVM, Nutanix, public cloud solutions). Dependency Mapping - Identify applications tightly linked to VMware—for example, backups based on VMDK—and evaluate concrete migration risks. 12-18 Month Roadmap - Define clear milestones: pilot proof of concept, migration of non-critical workloads, performance testing, and finally full transition.
A well-conducted audit not only highlights inefficiencies but also provides concrete data to justify investment.
Useful Resources and Professional Support Specialized Consultants - Red Hat Consulting, Accenture Cloud & AI, and partnerships with Nutanix offer tailored evaluation and migration paths. Active Communities - VMware Communities, the KVM forum, and LinkedIn groups dedicated to Cloud Native are excellent for connecting with those who have already completed the journey. Migration Tools - VMware vMotion, KVM live-migration, Nutanix Move, and Azure Migrate significantly accelerate timelines. Continuous Training - Platforms like Udemy and Coursera, along with official certifications (VMware Certified Professional, Red Hat Certified Specialist), can close the skills gap for your team.
📊 The Numbers
KPI Current VMware Alternative Solution (KVM/Nutanix) ----- ---------------- -------------------------------------- Annual TCO €1,200,000 €750,000 Provisioning Time 4 hours 30 minutes Downtime Percentage 0.5% 0.1%
A Clear Example
Bank of Horizon, a regional bank with 800 branches, chose to abandon VMware for a hybrid KVM and Nutanix solution. After a 60-day audit, they discovered that 35% of VMs were oversized. The migration was carried out in three phases: a pilot across 20 branches, a test across 200 branches, and full rollout within 12 weeks. The results? A 30% reduction in operational costs, a 70% reduction in downtime, and a fivefold faster scaling capability. Leadership defined the choice as "one of the most important strategic decisions of 2023."
💡 Did you know: migrating to KVM saved over 40% on licensing costs, for the same computing capacity. All thanks to the open-source nature of the platform.
Change is no longer an option; it's a necessity. If you want your company to remain competitive, the next decision could make the difference between being a leader or a follower. Don't let technology reach you first: take command, plan, act.
What are the next steps your organization needs to take to transform this vision into reality?
