An open-source integration between OpenNebula and Waldur has launched to unify AI workloads and cloud infrastructure across Europe’s sovereign supercomputing networks.
A major technological integration between two key European open-source cloud management platforms—OpenNebula, an AI infrastructure management platform, and Waldur, a self-service marketplace and federation portal developed by OpenNode—was officially established in July 2026.
The integration combines OpenNebula with Waldur’s self-service marketplace and federation layer via a dedicated provider site-agent plugin. Users can request, deploy, and manage both traditional virtual machines (VMs) and AI models or workloads through a single service catalog and interface. This capability allows Waldur to connect multiple separate OpenNebula instances, providing centralized access across distributed, multi-site cloud and AI infrastructures.
The solution avoids single-stack vendor lock-in, rendering interoperable, federated environments more practical for high-performance computing (HPC) centers, AI Factories, neoclouds, and telecom operators. The collaboration is designed to support Europe’s push toward data residency and sovereign cloud strategies, ensuring organizations maintain localized control over their infrastructure.
Developed by OpenNode and open-source contributors, Waldur serves as a core technology for the EuroHPC Federation Platform. This integration directly reinforces the EuroHPC initiative to link European supercomputing facilities and emerging AI Factories into a unified ecosystem. Executive leadership from both OpenNebula Systems and OpenNode noted that the combination makes highly complex distributed systems and massive future “AI Gigafactories” easy to consume without sacrificing open-source flexibility.
