Powering Sovereign AI Factories and Neoclouds
From Metal to a Production-Ready AI Cloud Service
OpenNebula is a vendor-neutral open platform for building and operating secure, multi-tenant AI factories that deliver AI-as-a-Service environments for HPC centers, Neoclouds and Telcos.
Why OpenNebula?
Open and Sovereign by Design
Avoid vendor lock-in with an open platform that gives you long-term control over your AI infrastructure, software stack, and operational roadmap.
Production-Proven AI & Kubernetes
Run cloud-native Kubernetes workloads alongside large-scale HPC and AI environments on infrastructure trusted in production for more than 18 years.
Predictable Costs at GPU Scale
Reduce total cost of ownership with a transparent, infrastructure-centric pricing model designed for large-scale GPU clusters and AI factory deployments.
Integrated AI Ecosystem
Deploy and manage validated AI frameworks and tools—including NVIDIA NIM, vLLM, and Hugging Face—through a unified cloud interface for operators and end users.
Strategic Partnership with NVIDIA
OpenNebula integrates with the NVIDIA AI infrastructure ecosystem to provide an open, sovereign cloud management layer for building and operating enterprise-scale AI Factories. It is integrated with NVIDIA DSX OS and key NVIDIA infrastructure technologies, including GPUs, NVLink/NVSwitch, BlueField DPUs, Spectrum-X Ethernet, and InfiniBand, providing a unified management layer across compute, networking, and accelerated infrastructure.
As the only cloud platform validated through the NVIDIA AI Cloud-Ready ISV program, OpenNebula combines NVIDIA-validated infrastructure capabilities with multi-tenancy, automation, virtualization, bare metal, Kubernetes, and AI workload orchestration.

Trusted by Industry Leaders
A proven platform, validated by customers, partners, and leading technology ecosystems.
“OpenNebula has been a game-changer for our innovation team at Telefónica Innovación Digital, enabling us to deploy and manage AI-powered environments with unparalleled flexibility. As a private cloud solution, OpenNebula allows us to efficiently share infrastructure resources—including GPUs—across multiple teams, fostering collaboration and accelerating our development cycles. We can seamlessly provision, scale, and optimize AI workloads, eliminating the complexity of managing dedicated hardware and reducing operational overhead. OpenNebula not only enhances our efficiency but also ensures that all teams have on-demand access to high-performance computing resources, making AI development more accessible and streamlined.”
“We’re using OpenNebula to address and reduce the complexity of heterogeneous hardware and the various software that runs either AI workloads directly or other frameworks, all while dealing with the constant evolution of requirements and capabilities. What we really like about OpenNebula is how easy and, especially, flexible it is. It’s very intuitive and saves us time. And of course, the GPU passthrough—an absolute must for any type of AI workload—works flawlessly without any issues.”
“The collaboration between OpenNebula and Iguane Solutions began in 2018. We use OpenNebula as a core pillar of our AI platform, which consists of three layers: hardware, OpenNebula, and LLM core services. On top of this, we can integrate any application to run AI workloads. Together with OpenNebula, we are building the next generation of open source clouds.”
