Digital Sovereignty in Practice

The internet was built on the promise of a borderless world. That promise is fading.
Today, political tensions, extraterritorial legislation, dependence on a handful of global technology providers, and fragile supply chains are reshaping the digital landscape. Digital sovereignty has be-come a practical challenge for governments, organizations, and the architects who design their digital infrastructure.
Digital Sovereignty in Practice bridges the gap between policy and technology. It explains why Eu-rope's ability to control its own digital infrastructure, data, and critical technologies has become a strategic priority, and shows how these ambitions can be translated into practical architectural deci-sions.
Drawing on real technologies and implementation strategies, the book explores topics including cloud infrastructure, open-source virtualization, European cloud providers, cybersecurity, secure collabo-ration platforms, procurement frameworks, and the legal and geopolitical forces shaping today's digi-tal world.
Whether you are an architect, technology leader, policymaker, student, or cybersecurity profession-al, this book provides both the strategic context and the practical guidance needed to design resilient digital infrastructures for an increasingly fragmented world.
Digital sovereignty is not achieved through declarations or strategy papers. It is built - one architec-tural decision at a time.
