- 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).

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 is OpenNebula?
OpenNebula is a powerful, enterprise-grade open-source virtualization and cloud management platform. It allows you to build and manage private and hybrid clouds with full control, using KVM virtualization and supporting multi-datacenter and edge deployments. Unlike bloated, proprietary solutions, OpenNebula gives you freedom, flexibility, and performance—without vendor lock-in.
Is this really simpler than VMware?
Yes — the Nubius Virtualization Platform is designed for clarity, speed, and control. Unlike VMware, which requires multiple complex layers (NSX, vSAN, Aria), our platform (based on OpenNebula + KVM) offers a unified interface that’s easy to operate from day one. No steep learning curve. No vendor maze. Just powerful results.
Can I keep using my own hardware?
Absolutely. You’re not locked into specific vendors. Our platform is hardware-agnostic and designed to work with your existing infrastructure, whether on-prem, colocation, or bare metal in the cloud. You keep control and avoid unnecessary spending.
Will I be stuck with high licensing costs like with VMware?
Not at all. Our pricing is flat-rate per host — no per-core or per-feature licensing. That means predictable costs and significant savings, especially as you scale. Many customers report up to 90% lower TCO compared to VMware.
Can my team operate it, or do we need to rely on Nubius 100%?
You choose. We offer both fully managed and co-managed models. You can operate the platform internally and rely on our team for Tier 3 support or special projects — or let us manage everything end-to-end. Flexibility is built-in.
What kind of infrastructure do I need to get started?
We’ll help you assess what’s best based on your workloads. Whether you have on-prem servers, a preferred colocation facility, or need help deploying in the cloud — we’ll tailor the setup and support to fit your environment and growth plans.
What kind of support is included — and what isn’t?
Every deployment includes premium support for the platform itself, covering the full OpenNebula stack: hypervisors, optimizations, and troubleshooting within the virtualization layer.
What’s not included by default are day-to-day operational tasks inside your virtual machines, application-level issues, or major infrastructure changes like adding new zones or network reconfiguration. For these, we offer flexible OpsAssist blocks, so you can get expert help exactly when you need it — without committing to a full-time service contract.
Are you an official OpenNebula partner?
Yes — Nubius Solutions is a certified Managed Cloud Partner of OpenNebula. We’re proud to be one of the few recognized partners in the Americas. This means we have direct access to the OpenNebula team, best practices, and premium support channels — so you get top-tier infrastructure expertise with every deployment.
