In a move that reflects Europe’s deepening concerns over data sovereignty and foreign technological dependence, France has decided to move its national Health Data Hub away from Microsoft's cloud infrastructure and into the hands of domestic provider Scaleway. The decision marks one of the most significant shifts yet in Europe’s growing effort to reclaim control over sensitive public data.
The Health Data Hub contains medical information relating to millions of French citizens and serves as a major research platform for healthcare analysis and innovation. Since 2019, the system had been hosted on Microsoft Azure, a decision that triggered years of political and legal controversy due to fears surrounding American surveillance laws and extraterritorial access to European data.
French authorities have now selected Scaleway, a subsidiary of Iliad, after an extensive evaluation involving more than 350 technical criteria related to security, resilience, and operational capacity. The migration is expected to be completed between late 2026 and early 2027.
Why Europe Is Growing Wary of American Cloud Giants
The decision is part of a much broader European movement toward what policymakers increasingly describe as “digital sovereignty.” Governments across Europe have become increasingly uneasy about relying on American technology firms for critical infrastructure, especially after repeated debates surrounding the US CLOUD Act, which can compel US companies to provide data to American authorities even if that data is stored overseas.
In France, these concerns intensified after Microsoft reportedly acknowledged before a French Senate inquiry that it could not fully resist certain US government data requests involving French citizens. That revelation significantly strengthened calls for sovereign cloud infrastructure controlled entirely within European legal jurisdiction.
The shift also aligns with France’s wider technological repositioning. Earlier this year, the country announced plans to reduce reliance on Microsoft products across government systems, replacing several US-based platforms with domestic or open source alternatives.
A Defining Moment for Europe’s Tech Independence
France’s decision extends beyond healthcare infrastructure as it clearly represents a symbolic turning point in Europe’s evolving relationship with Big Tech.
For years, European nations depended heavily on American cloud providers because of their scale, maturity, and technological dominance. But growing geopolitical tensions, concerns around privacy, and the strategic importance of data have begun reshaping that equation.
By transferring one of its most sensitive national databases to a domestic provider, France is effectively signalling that technological convenience can no longer outweigh sovereignty concerns. The move may now encourage other European governments to reassess where their own critical data resides.
At its core, this is no longer simply a cloud migration story. It is a declaration that, in the age of AI and mass data infrastructure, control over information has become inseparable from national security itself.
