Why Nubius Virtualization Platform?
Simplify Virtualization Without Losing Control
Many vendors tack on fees, complexity, or lock‑in. We fix that by letting you deploy VMs or containers simply, predictably, and on your terms.
- VMware replacement no licensing headaches
- Fully managed from setup to optimization
- Flexible: deploy on-prem, in cloud, or colocation
- Based on OpenNebula with KVM for high performance
From Setup to Success
Provision
We deploy and configure your platform on bare metal (on-prem, cloud, or colo).
Operate
You access the UI and start launching VMs and managing services.
Support
We provide premium support and optional OpsAssist for daily operations.
Choosing the Right Virtualization Platform: OpenNebula vs the Rest
From VMware to Proxmox, see how OpenNebula compares and why more businesses are making the switch.
Replace VMware’s complexity and lock-in with open-source freedom and predictable pricing.
Why Switch from VMware to Our Virtualization Platform?
| Feature | OpenNebula (Nubius Platform) | VMware |
|---|---|---|
| Total Cost of Ownership (TCO) | Up to 90% lower TCO — 5x to 30x cost savings depending on server specs and scale | Per-core licensing increases costs rapidly as infrastructure grows |
| Flexibility & Customization | Open source, hardware agnostic, built for gradual migration | Proprietary stack with limited portability and high switching costs |
| Simplicity & Ease of Use | Quick to deploy and manage with a unified interface | Complex setup requiring many components (NSX, vSAN, Aria, etc.) |
| Multi-site & Hybrid Cloud | Native support for federated, hybrid, and edge environments | Limited features unless using 3rd-party or enterprise add-ons |
| Pricing Model | Flat-rate per host — predictable OpEx | Per-core licensing with higher costs at scale |
| Kubernetes & Containers | Includes certified Kubernetes (OneKE) with autoscaling, HA, and orchestration | Requires Tanzu — only available in higher bundles |
Proxmox VE is a solid choice for virtualization in small to mid-sized environments. But when your needs grow — from hybrid cloud integration to true multi-tenancy and global support — it begins to show limitations.
How Does OpenNebula Compare to Proxmox Enterprise?
| Feature | OpenNebula (Nubius Virtualization Platform) | Proxmox VE (Enterprise Edition) |
|---|---|---|
| Pricing Model | Flat-rate per server — scalable and predictable | Per CPU socket — can become expensive at scale |
| Enterprise Support | 24/7 global support with optional expert services | Business hours only (CET), limited ticketing per year |
| Hybrid & Edge Cloud Readiness | Built-in multi-cloud, hybrid, and edge infrastructure support | On-prem focus with no native hybrid or edge capabilities |
| Automation & Orchestration | Advanced orchestration, self-service portals, and federation | Limited automation — primarily cluster-level management |
| User Experience & Multi-tenancy | Enterprise-ready with unified UI and native multi-tenancy | Simplified UI — lacks enterprise multi-tenant design |
| Licensing Flexibility | Open-source core + optional enterprise add-ons — no vendor lock-in | AGPL-based core, but support tied to subscription model |

Got Questions? We’ve Got You Covered.
What are virtualization solutions?
Virtualization solutions are software platforms that abstract physical compute, storage, and network hardware into pooled virtual resources. A hypervisor layer allows a single physical server to run multiple isolated virtual machines, each with its own operating system and allocated resources. The result is higher hardware utilisation, faster provisioning, and workload isolation without buying additional physical servers.
What are the four types of virtualization?
The four most commonly cited types are server virtualization, desktop virtualization, network virtualization, and storage virtualization. Server virtualization partitions one physical host into multiple virtual machines. Desktop virtualization delivers user desktops from a centralised host. Network virtualization abstracts switching and routing into software-defined networks. Storage virtualization pools disks across multiple devices into a single logical volume.
What are examples of virtualization?
Common examples include running multiple Linux and Windows virtual machines on a single physical server, delivering virtual desktops to remote staff, creating software-defined networks and VLANs without additional switches, and pooling disks from several nodes into one logical storage volume. Containers and virtualized GPU workloads are further examples of the same abstraction principle applied at different layers.
What are the 5 stages of virtualization?
A virtualization project typically moves through five stages: assessment of current workloads and hardware, architecture design covering host sizing, storage, and network topology, deployment of the hypervisor and management layer, migration of workloads from physical to virtual, and ongoing optimisation covering capacity, backup, and performance tuning.
What skills are needed for virtualization?
Core skills include hypervisor administration, Linux and Windows server administration, networking fundamentals such as VLANs, routing, and firewalling, storage concepts including RAID, iSCSI, and distributed storage, and capacity planning. Backup and disaster recovery design, scripting for automation, and security hardening round out the required skill set. Most organisations either build this in house or use a managed provider.
What are the 4 components of virtualization?
The four components are the physical host hardware providing CPU, memory, storage, and network capacity, the hypervisor that abstracts and schedules those resources, the virtual machines with their guest operating systems and applications, and the management layer used to provision, monitor, and orchestrate the environment.
