Open Sovereign AI + Cloud Day Europe 2027

Open Sovereign AI + Cloud Day Europe 2027 is a one-day, CNCF-hosted co-located event of KubeCon + CloudNativeCon Europe, held in Barcelona, Spain on March 15, 2027. It looks at how open source technology supports digital sovereignty in Europe and elsewhere, with open, standards-based approaches that avoid lock-in while meeting requirements for regulatory compliance, data residency and operational resiliency. The 2027 programme is organised around six topics: sovereignty in practice, data and AI sovereignty, operational resiliency, supply chain and technology sovereignty, security and compliance, and public sector and regulated use cases. The event first ran as Open Sovereign Cloud Day in Amsterdam in March 2026, where an OVHcloud recap singled it out among the 16 co-located events. For 2027, AI was added to its name. KubeCon Europe itself runs March 15 to 18, 2027.

European data-residency rules and AI regulation are making sovereignty a procurement requirement, and it is hard to pin down what that means for a Kubernetes and AI stack. This day puts CIOs, public sector buyers and platform teams in one room with the maintainers of the open source projects those stacks run on. You come away with the patterns others use for residency, compliance and supply-chain control. The full KubeCon week then lets you check vendors' claims against end users. Book an All-Access pass, since there is no co-located-only ticket.
