Our commitments
Modularity
Faced with the growth in computing power needs, new scalable infrastructures are needed, offering power densities per rack up to thirty times greater than traditional cloud data centers and integrating advanced, more efficient cooling solutions.
Security
The architectures incorporate advanced data protection devices, guaranteeing their confidentiality and integrity. The infrastructures and processes comply with European regulatory requirements and international information security standards, in particular ISO 27001.
Sustainability
Eclairion is committed to the responsible design and operation of its infrastructures, combining sobriety of materials, limitation of the artificialization of soils, high energy and water efficiency, use of carbon-free energies and valorization of residual heat.
Sovereignty
The deployment of infrastructures for hosting artificial intelligence clusters in Europe is a key issue of economic and digital sovereignty. Faced with the rise of AI in strategic sectors and its impacts on competitiveness and employment, the development of an ecosystem and sovereign AI models, hosted within the European Union, is essential.
