At a time when digital sovereignty and ecological transition are becoming top priorities, the sovereign datacenter stands out as a key lever.
During a round table organized by OUTSCALE, Antoine Fournier (Thésée Data Center) and David Chassan (OUTSCALE) shared their insights on this strategic topic.
A rich and thought provoking discussion centered on one essential theme: the role of sovereign datacenters in building a trusted, resilient, high-performance, and compliant digital ecosystem.
Digital Sovereignty: A Chain of Trust That Begins with Infrastructure
Digital sovereignty goes far beyond data localization. It relies on a chain of trust and the first and most tangible link is physical: the datacenter.
« Every cloud service, every AI, at some point, needs a physical infrastructure to operate. » Antoine Fournier, Thésée Data Center
The datacenter is not just a container, it is the very foundation of strategic autonomy. At OUTSCALE, this means a clear responsibility: working only with partners capable of guaranteeing the highest standards in security, compliance, performance, and sustainability.
Demanding Certifications: Guarantees of Trust and Transparency
One of the highlights of the round table was the emphasis on certifications as tangible proof of strong commitments to sovereignty:
- TIER IV: the highest standard of resilience for hosting critical data
- SecNumCloud 3.2: the ANSSI qualification, the French and European reference for trusted cloud infrastructure
- CISPE: the only certification recognized by the CNIL ensuring that data remains within Europe and is processed in full compliance with the GDPR
These certifications are not just labels, they are part of a transparent, controlled, and continuously improving approach. As an example, Thésée recently conducted a full scale intrusion test in collaboration with law enforcement to strengthen its internal security systems.
OUTSCALE & Thésée: An Industrial and Eco-Responsible Partnership
With over 380,000 clients and 45 million users worldwide, OUTSCALE embraces a strict industrial approach. Its partnership with Thésée is built on three strategic pillars: security, operational excellence, and eco-responsibility.
Together, we:
- Are committed to the Climate Neutral Data Centre Pact, aiming for climate neutrality by 2030
- Invest in technologies such as direct water cooling, waste heat reuse, and closed-loop systems
- Integrate energy efficiency criteria from the design phase (“PUE by design”)
« We must be industrial in our approach, with extremely rigorous choices. Deploying our cloud services in datacenters like Thésée means ensuring high levels of security, performance, and sustainability. » David Chassan, OUTSCALE.
Toward European Digital Autonomy…
The conclusion of this round table was clear: strategic autonomy is not declared, it is built. It is based on:
- Certified and reliable partnerships
- Resilient and ethical infrastructure
- A shared commitment to embedding digital transformation within a long-term vision, respectful of both sovereignty and the environment
OUTSCALE & Thésée embody this ambition.
Together, they are building the foundations of a trusted European digital future.
