Architecting Portable Systems on Open Standards for Digital Sovereignty

Digital sovereignty is about maintaining control over critical systems by reducing reliance on any single vendor. Full independence is impossible, but organizations should identify critical systems and apply portability strategies selectively. Open standards — including de facto standards like Kubernetes, PostgreSQL, and Kafka — are the primary mechanism for achieving portability, as they make vendor switching feasible and demand elastic. Real-world examples like HashiCorp's license changes and Broadcom's VMware pricing illustrate the risks of proprietary lock-in. Enterprise architects must establish guardrails that enforce portable design without creating excessive friction, balancing sovereignty goals against the operational cost of increased migration cadence.
