When we started exploring options to replace our old virtualization system, we weren’t just looking for new features—we were looking for a reliable, future-proof OpenNebula implementation that could scale, integrate with our existing investments, and avoid vendor lock-in.
The mission was clear: find a virtualization solution that would last, deliver flexibility, integrate seamlessly, and not drain the budget. But first, we had to overcome some very real challenges.
The Problems We Needed Our OpenNebula Implementation to Solve
1. Outdated features and poor isolation
Our previous platform lacked modern networking standards. Deployments in one VM could affect others, risking outages.
We needed a true private cloud with fully isolated internal networks.
Our OpenNebula implementation solved this by introducing VXLAN-based networking, giving us stronger isolation and far more subnet flexibility.
It also allowed customers to manage their own ISOs, upload custom images, create templates, and handle more tasks without backend intervention, something they couldn’t do before.
2. Security and privacy demands
High-end customers want control; dedicated firewalls, VPNs, and strict access rules.
By integrating OpenNebula with OPNSense, we gave each private cloud its own dedicated VPN/firewall stack, improving flexibility, security, and control.
3. Vendor lock-in and pricing pressure
The old platform kept raising prices and changing pricing models, much like what’s happening with VMWare today. Our OpenNebula implementation freed us from these constraints, offering predictable costs and no vendor lock.
4. Integration flexibility
We had already invested heavily in upgrading our storage systems, and needed a virtualization platform that could integrate seamlessly, not only with storage but also with our customer portal for billing and service management.
OpenNebula’s API and available integrations made this straightforward.
5. Future-proof technology
We weren’t looking for a quick fix; we needed a platform that would continue evolving, support emerging standards, and let us expand our services.
Why We Chose OpenNebula Over OpenStack, Proxmox, and CloudStack
When evaluating options, we looked at OpenStack, Proxmox VE, and Apache CloudStack:
- OpenStack – Extremely powerful but overly complex for lean, high-performance setups. Heavy operational requirements made it less attractive.
- Proxmox VE – Simple and cost-effective, but missing advanced enterprise networking, multi-site federation, and hybrid-cloud capabilities.
- Apache CloudStack – Stable for large-scale public cloud environments, but more complex to integrate with our existing workflows.
OpenNebula offered the right balance: enterprise-grade capabilities, easier deployment, seamless integration, and lower operational overhead.
The Results of Our OpenNebula Implementation
Years later, we can confirm it was the right choice. OpenNebula has continued to evolve, adding orchestration, GPU support, hybrid multi-cloud integration, and more—while remaining stable and cost-effective.
Some of the benefits we’ve seen:
- Better performance with isolated, optimized environments.
- Less downtime, even during major changes.
- Greater end-user autonomy through self-service tools.
- Lower operational costs by avoiding licensing traps.
- Peace of mind for IT teams and management.

Beyond Deployments: Optimization and Modernization
In recent projects, we’ve been working closely with customers who already have OpenNebula but aren’t getting the best out of it.
We’ve found and fixed bottlenecks caused by improper configurations, improved stability, and addressed performance issues in environments we didn’t originally implement.
We’ve also been engaged in evaluating entire virtualization stacks for customers stuck on outdated platforms, showing them exactly how OpenNebula overcomes their current pains, modernizes their infrastructure, and sets them up for growth.
Our Partnership with OpenNebula
When we founded Nubius Solutions, we became an official OpenNebula Managed Cloud Partner, one of the few in the Americas.
You can find us listed on OpenNebula’s Business Partner page, alongside other certified experts.
This partnership ensures we have direct access to OpenNebula’s roadmap, resources, and support, bringing even more value to our customers.
