Your VM Workloads, Cloud-Native Ready
Move Beyond VMware: Unify Your Infrastructure with Kubermatic
Situation
The Broadcom Ultimatum and the Hypervisor Tax
Broadcom’s acquisition of VMware has fundamentally reshaped the virtualization landscape. For enterprise organizations, migrating away from VMware has shifted from a long-term strategic option to an urgent economic mandate.
For many organizations, staying on VMware is now more expensive and riskier than moving away.
The Challenge: Enterprises face a narrow window to act, but migration is fraught with operational risk:
- Proprietary Silos: Replacing VMware with another proprietary stack offers no functional improvement.
- Tooling Overhead: Maintaining separate environments and separate teams for Virtual Machines (VMs) and modern containers drains IT budgets.
- Disruption Risk: Migration requires careful coordination and planning across teams and executives. Migration errors can disrupt critical systems.
How we help
The Unified KubeVirt Platform
Kubermatic enables a structured, de-risked escape route from VMware. We do not offer a simple “like-for-like” hypervisor replacement; we deliver true platform unification.
By integrating KubeVirt technology directly into the Kubermatic Kubernetes Platform (KKP), organizations can natively run legacy virtual machines alongside cloud-native container workloads within a single environment.
The Architectural Shift:
Kubermatic unifies compute, storage, and networking under the universal Kubernetes API, replacing proprietary VMware components with open-source, declarative equivalents:
| Legacy vSphere Concept | Kubermatic (KubeVirt) Equivalent | The Business Outcome |
|---|---|---|
| vCenter Server | Kubernetes API (Control Plane) | Shift from proprietary GUIs to automated, GitOps-driven workflows. |
| ESXi Hypervisor | KVM/QEMU in a virt-launcher Pod | The hypervisor becomes a process inside a pod, fully scheduled by Kubernetes. |
| Datastore (vSAN) | PersistentVolumeClaim (PVC) via CSI | Break free from monolithic storage; utilize any standard storage backend. |
| vSwitch / VLAN | CNI + Multus | Software-defined networking mapping legacy VLANs directly into Kubernetes. |
| vMotion | KubeVirt Live Migration API | Seamless workload mobility with zero downtime. |
The Migration Path
The biggest challenge is not the technical move itself. It is the operational mindset shift required across teams. Kubermatic Virtualization provides a gradual, 4-phase migration path:
1. Assessment and Strategy
Build a comprehensive VM inventory and establish performance baselines. Classify workloads to retire, refactor, or rehost (lift-and-shift) while identifying a low-risk pilot to validate the approach.
2. Platform Foundation and Pilot
Deploy the KubeVirt platform including KKP, storage (CSI), and networking (Multus). Conduct a controlled pilot to verify critical features like Live Migration and High Availability, resulting in a repeatable migration runbook.
3. Scaled Execution
Migrate workloads in organized waves. Use Rehost for fast, "as-is" transfers of legacy apps, or Refactor for high-value applications that require cloud-native optimization.
4. Optimization and Day-2 Governance
Fine-tune resources post-migration and implement GitOps for unified VM and container management. Finally, decommission legacy vSphere resources to fully realize TCO savings.
Real-World Use Cases
Legacy Application Rehosting (Immediate Cost Relief)
- The Mission: Eliminate VMware licensing costs immediately without modifying legacy application code.
- The Application: Lift-and-shift monolithic applications directly into KubeVirt pods. The legacy VM runs exactly as before, but the “hypervisor tax” is entirely eliminated.
Gradual Application Modernization (Refactoring)
- The Mission: Modernize legacy systems without disrupting mission-critical business operations.
- The Application: Run existing VMs on the Kubermatic platform to establish a stable baseline. Over time, engineering teams can progressively decompose the monolithic VM into modern microservices, side-by-side on the exact same platform.
Unified Edge Operations
- The Mission: Standardize operations across highly distributed environments like retail stores or factory floors.
- The Application: Run both legacy VM-based systems (like Windows point-of-sale or MES) and modern containerized AI workloads together at the edge, managed via a single centralized interface.
Outcome
Zero Tax, Unified Teams, and Total Freedom
By migrating from VMware to Kubermatic, organizations transition from restrictive legacy virtualization to an agile, future-proofed cloud-native foundation.
Zero Hypervisor Tax
Instantly eliminate costly, proprietary VMware subscriptions and avoid forced product bundling.
Operational Unification
Merge “Team VM” and “Team Container” into a single Platform Engineering unit. Manage VMs using modern GitOps and Ansible automation — treating legacy infrastructure as code.
Strategic Flexibility (No Vendor Lock-in)
Standardize entirely on the open Kubernetes API. Run your workloads anywhere — on bare metal, in the public cloud, or at the edge — on any certified hardware.
De-Risked Migration
Balance financial pressure with operational safety by utilizing our structured pilot-to-scale runbooks, ensuring high availability during the transition.
