France Shifts National Health Data from Microsoft to Local Cloud Provider

9

France has officially decided to migrate its national Health Data Hub from Microsoft Azure to Scaleway, a French cloud provider owned by the telecommunications group Iliad. This move marks a significant pivot in how the country manages its most sensitive digital assets.

The Mission of the Health Data Hub

The Health Data Hub is designed to be a massive digital repository, replicating the entire French National Health Data System (SNDS). By centralizing the medical records of tens of millions of citizens, the platform aims to provide researchers with a high-quality, large-scale resource to drive medical innovation and long-term clinical studies.

While Microsoft was originally selected to host the infrastructure in 2019, the project faced significant hurdles that ultimately led to this strategic reversal.

Privacy, Security, and the “Cloud Sovereignty” Conflict

The decision to move away from Microsoft was driven by deep-seated concerns regarding data sovereignty and legal jurisdiction. Even though data might be physically stored on servers within French borders, the legal reality of US-based providers remains a sticking point for European regulators.

Key issues included:
Extraterritoriality: Under American law, US-based companies can be compelled to grant authorities access to data, regardless of where that data is physically located.
Regulatory Friction: France’s data protection authority, the CNIL, raised critical alarms regarding the potential for unauthorized access to sensitive medical information.
Legislative Mandates: In 2024, France passed a law requiring “sovereign-guaranteed” hosting for sensitive data, effectively making the use of non-European providers for such critical infrastructure legally precarious.

“This migration is part of a long-standing effort to maintain a high level of security and trust for all users of the platform,” stated Hela Ghariani, Director of the Health Data Platform.

A Growing European Trend Toward Digital Autonomy

France’s move is not an isolated incident; it is part of a broader continental movement to reduce strategic dependency on American “Big Tech.” European nations are increasingly prioritizing digital sovereignty to ensure that public administration and sensitive citizen data remain under local legal control.

Similar shifts are visible across the continent:
Germany: The state of Schleswig-Holstein is transitioning 30,000 government workstations away from Microsoft software.
Denmark: Various public administration sectors are adopting open-source alternatives like LibreOffice.
European Commission: The EU has bolstered this trend by awarding a €180 million cloud contract to a consortium of European providers, including Scaleway, OVHcloud, STACKIT, and Post Telecom.

Looking Ahead

The transition to Scaleway is expected to continue through the coming months. The Health Data Hub is projected to be fully operational between late 2026 and early 2027, at which point it will serve as a cornerstone for health-driven research and innovation across Europe.


Conclusion: By replacing Microsoft with Scaleway, France is prioritizing legal sovereignty and data privacy over the convenience of established US tech giants, setting a precedent for how European nations manage sensitive public information.
