Open Sovereign Cloud Day

Open Sovereign Cloud Day brings together cloud native practitioners, maintainers, and private and public sector stakeholders to explore how open source technologies enable digital sovereignty across Europe and beyond.

As governments, enterprises, and critical industries seek greater control over data, infrastructure, and supply chains, cloud native technologies play a foundational role in building interoperable, resilient, and transparent systems. This event focuses on open, standards-based approaches to sovereignty—avoiding lock-in while supporting regulatory compliance, data residency, and operational resiliency.

Through real-world case studies, technical deep dives, and community discussions, Open Sovereign Cloud Day highlights how the CNCF and Linux Foundation ecosystems are being used to design, deploy, and operate sovereign cloud platforms—from public sector infrastructure to regulated industries and cross-border collaboration in a rapidly evolving geopolitical landscape.

This event is designed for those working on building and operating sovereign cloud infrastructure, navigating regulatory compliance and data residency requirements, developing open standards for interoperable platforms, contributing to cloud native projects with sovereignty considerations, shaping digital policy and procurement strategies, and deploying critical infrastructure in regulated sectors.

This event is one of our KubeCon + CloudNativeCon Europe CNCF-hosted Co-located Events. In-person attendees have the option to register for an All-Access In-Person KubeCon + CloudNativeCon pass that will include entry to ALL CNCF-hosted co-located events + KubeCon + CloudNativeCon.
