Open Source as the Foundation of EU Digital Sovereignty

You can't claim digital sovereignty if your infrastructure depends on proprietary software from foreign companies. If Microsoft changes Windows licensing, if Oracle changes database terms, if VMware changes virtualization pricing — you're exposed. Open source eliminates this dependency. It's not just cheaper; it's strategically sovereign.

The Sovereignty Argument for Open Source

• No vendor kill switch — No single entity can revoke your right to use the software
• Inspectable code — You can verify there are no backdoors, no telemetry to foreign servers, no hidden dependencies
• Fork rights — If a project changes direction (Redis, Elasticsearch, HashiCorp), the community can fork
• European contributions — European developers and companies actively contribute to and lead major open-source projects
• No license compliance risk — Open-source licenses don't change retroactively (unlike proprietary EULAs)

The Sovereign Open-Source Stack

• Operating system — Linux (any distribution — Debian, Ubuntu, RHEL, SUSE)
• Container runtime — containerd, CRI-O
• Orchestration — Kubernetes
• Service mesh — Istio, Linkerd, Cilium
• Databases — PostgreSQL, MariaDB, Apache Cassandra, Redis (open-source fork: Valkey)
• Message queues — Apache Kafka, RabbitMQ, NATS
• Monitoring — Prometheus, Grafana, OpenTelemetry
• CI/CD — GitLab (EU company), Jenkins, ArgoCD, Tekton
• AI/ML — PyTorch, KubeFlow, MLflow, Triton
• Security — Falco, Open Policy Agent, Keycloak

European Open-Source Leadership

Europe already leads significant open-source projects: Linux (Linus Torvalds — Finnish/European), GitLab (Dutch-Ukrainian), SUSE (German), Nextcloud (German), MariaDB (Finnish), Collabora (UK). Supporting and expanding European open-source infrastructure is both a sovereignty strategy and an economic opportunity.

The EU Policy Framework

EU institutions increasingly mandate open source: European Commission's Open Source Strategy 2020-2023, EU Interoperable Europe Act (preference for open-source solutions), multiple member states with open-source-first policies. Aligning your infrastructure with open source aligns with both sovereignty goals and EU policy direction.
