Sovereign Cloud emphasizes control, transparency, interoperability, and compliance:
- Operate and store data under jurisdictions you choose.
- Prefer open standards and open source to avoid lock-in.
- Enable portability across providers and on-prem/edge.
- Make security, privacy, and auditability first-class.
If it increases digital autonomy (technical, operational, legal), it likely belongs here.
