ATOS Les Clayes-sous-Bois

The Atos data center in Les Clayes-sous-Bois, inaugurated in December 2018, is a scalable, modular facility built on the company’s historic site west of Paris. Designed to meet rising demand for high-performance digital infrastructure, the center initially launched with 1,300 m² of operational space across two modules, with plans to expand to 8,000 m² by 2020 through eight modules in total.

Developed with a €60 million investment, the site was built in partnership with the Yvelines departmental council, which provided long-term land access to support Atos’ strategic growth. The facility targets energy efficiency and cutting-edge standards to host clients across sectors such as healthcare, defense, and industry, offering secure data hosting and storage services.

Positioned as a cornerstone in Atos' French data center portfolio—which includes 15 sites nationwide—this development reinforces the company's commitment to sustainability, security, and digital innovation.
