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.”
