As European investments in sovereign cloud, high-performance computing (HPC), and AI Factories continue to accelerate, OpenNebula and Waldur have announced a new integration designed to simplify how organizations deliver and manage AI-driven cloud services. The collaboration enables unified access to virtual machines, AI workloads, and distributed infrastructure through a single self-service interface, supporting Europe’s broader push toward digital sovereignty and federated AI ecosystems.
The integration between OpenNebula and Waldur is designed to support Europe’s growing focus on sovereign cloud infrastructure, AI Factories, and high-performance computing environments. By combining OpenNebula’s cloud and AI infrastructure management capabilities with Waldur’s self-service marketplace and federation layer, the solution enables organizations to operate complex distributed systems through a unified interface.
This approach aligns with the broader EuroHPC initiative, which aims to connect European supercomputing centers and AI infrastructure providers into a cohesive and interoperable ecosystem. The integration helps reduce operational complexity while improving accessibility to advanced computing resources.
With this integration, users can provision and manage both traditional virtual machines and AI workloads through Waldur’s centralized service catalog. OpenNebula provides the underlying infrastructure management, while Waldur delivers a user-facing marketplace that abstracts complexity across multi-site environments.
This enables organizations to support self-service provisioning, lifecycle management, and workload orchestration across distributed cloud and HPC systems. The platform is particularly suited for environments requiring multi-site deployment and federated infrastructure access.
A key feature of the integration is its ability to connect multiple OpenNebula instances through Waldur, creating a federated infrastructure layer. This allows organizations to manage resources across different locations while maintaining a unified operational view.
The model supports AI Factories and HPC centers that require scalable, interoperable infrastructure without locking into a single vendor ecosystem. It also enables consistent service delivery across research institutions, government platforms, and commercial cloud providers operating within sovereign cloud frameworks.
The integration is positioned as a foundational component of Europe’s emerging AI Factory and EuroHPC ecosystem. By enabling interoperability across cloud and HPC environments, the solution supports the development of large-scale AI infrastructure capable of handling distributed compute workloads and AI model deployment at scale.
Waldur, already widely adopted within the supercomputing community, plays a central role in the EuroHPC Federation Platform, which connects European HPC facilities under a unified operational framework. The integration with OpenNebula strengthens this ecosystem by extending support for AI-native workloads and cloud services.
Both OpenNebula and Waldur emphasize open, vendor-neutral design principles, enabling organizations to avoid lock-in while maintaining flexibility in infrastructure deployment. OpenNebula provides a unified control plane for cloud and AI infrastructure, while Waldur acts as an interoperability and self-service layer across heterogeneous environments.
This architecture allows organizations to preserve existing infrastructure investments while modernizing toward AI-ready cloud environments. It also supports the growing demand for sovereign infrastructure that aligns with regional data governance and compliance requirements.
The combined solution enables cloud and AI service providers to deliver multi-tenant environments where users can request and manage resources through a centralized catalog. This includes AI model deployment, virtual machine provisioning, and HPC resource allocation.
By standardizing service delivery through Waldur’s marketplace model, organizations can simplify access to complex infrastructure while maintaining control over underlying compute resources managed by OpenNebula.
The integration is particularly relevant for HPC centers, AI Factory initiatives, neocloud providers, and telecommunications operators. These organizations often manage large-scale distributed infrastructure that requires both operational flexibility and centralized governance.
By combining automation, federation, and self-service capabilities, the solution helps reduce operational overhead while enabling scalable AI and HPC service delivery across multiple environments.
The OpenNebula and Waldur integration reflects a broader shift toward interoperable, sovereign AI infrastructure across Europe. As AI workloads become more distributed and compute-intensive, organizations are increasingly adopting federated models that allow shared resource access without sacrificing control or compliance.
This collaboration strengthens the foundation for future AI Gigafactories and large-scale distributed computing environments, where seamless access to compute, storage, and AI services is essential for innovation and scalability.
OpenNebula Systems is the developer of OpenNebula, an open, vendor-neutral enterprise cloud and virtualization platform designed for sovereign clouds and AI factories. The company provides SLA-based support and professional services to enterprises, service providers, and public-sector organizations worldwide.
OpenNebula is increasingly adopted as a VMware replacement platform, enabling organizations to modernize and consolidate their infrastructure while preserving existing hardware investments and operational practices. At the same time, the platform has evolved to support AI Factories and AI Gigafactories, acting as a unified control plane for GPU-accelerated infrastructure, Kubernetes platforms, and large-scale AI workloads.
With a global presence and offices in Europe and the United States, OpenNebula Systems is a trusted partner for large-scale, mission-critical deployments, supporting more than 5,000 cloud deployments worldwide and infrastructures that scale to thousands of hosts and tens of thousands of GPUs.
OpenNode is a European software company and the creator of Waldur, an open source (MIT-licensed) platform for managing cloud, HPC, and AI infrastructure. Waldur gives providers a self-service marketplace and interoperability layer that turns complex, multi-vendor environments into resources users can request and consume on demand.
Widely adopted across the supercomputing community, Waldur is one of the core technologies of the EuroHPC Federation Platform and is deployed at leading European HPC facilities, national research systems, and government cloud services. OpenNode supports research institutions, public-sector bodies, and commercial providers with the software, integration, and expertise needed to run sovereign, federated infrastructure at scale. Headquartered in Tartu, Estonia, with a subsidiary in the United Kingdom, OpenNode pairs deep engineering expertise in HPC, cloud, and AI infrastructure with a commitment to open, vendor-neutral technology.
