The Sovereignty Stack // Part 5 — Series Finale Can You Actually Measure Digital Sovereignty? Can you identify the five technology dependencies your organisation would struggle most to replace? Not the five most expensive. Not necessarily the five most critical applications. The five dependencies where your organisation has the least strategic choice — where changing direction would be most costly, most disruptive, or most time-consuming. Most organisations can tell you where their applications run. They can tell you their cloud providers, their identity platform, their AI services. What they often cannot answer is the harder set of questions: Who ultimately controls those dependencies? How replaceable are they? And what would it actually take to leave? That is the difference between knowing your technology estate and understanding your sovereignty posture. And if digital sovereignty is an architectural property — which is the premise this series has...

The Sovereignty Stack // Part 4 Interoperability Is Not Enough — The Architecture of Strategic Choice Your Kubernetes strategy may be portable. Your service probably is not. A container can move between environments. But the identity model, secrets management, managed database, observability stack, API gateway, and operational knowledge that make that container a functioning service — those do not move automatically. In many cases, they do not move easily at all. You moved the workload. You did not necessarily move the capability. And that distinction sits at the heart of a question Enterprise Architecture rarely asks clearly enough. Does interoperability actually give us strategic choice — or just the appearance of it? After the first three parts of this series, the most common question from readers has been whether interoperability belongs under Platform Sovereignty or Standards Sovereignty. The answer is that it belongs across the entire stack — b...
