Open Source Summit Europe 2025

Cloud-native technologies are reshaping infrastructure strategies, especially as organizations embrace hybrid and multi-cloud models. In this session, we explore how the combination of Multi-Linux environments, Kubernetes, and virtualization forms the backbone of sovereign, cloud-native platforms. As regulatory and supply chain pressures elevate the importance of digital sovereignty, open source solutions—like SUSE-supported projects Rancher, K3s, and Harvester—offer a path and choice to control, agility, and compliance without vendor lock-in. We'll examine how diverse Linux distributions operate within Kubernetes clusters, how virtualization enhances workload isolation and portability, and how cloud-native architectures can be designed to meet sovereignty requirements. Attendees will gain insights into real-world implementations and open standards that are driving the next generation of sovereign cloud infrastructure.
