Roubaix, France – Kellermann Street in Roubaix, with its red brick buildings and the sounds of daily life, might seem like any other suburban street in northern France. However, one building stands apart: Roubaix 8, one of OVHcloud’s nine data centers in the region. Inside, a portion of the company’s 120,000 servers reside, representing an estimated 20-25% of the cloud provider’s global operations.
Gaining access requires donning protective gear and passing thru a security airlock. Inside lies the core of a European cloud hosting provider, a company generating billions in revenue and entrusted with vast amounts of data from both public and private entities. Recent geopolitical shifts have amplified interest in OVHcloud’s long-standing commitment to a “European and sovereign cloud.”
The promise of witnessing the infrastructure behind everyday digital activities – streaming,social media,and AI tools – becomes a reality within these walls. The tangible reality of data storage and processing becomes apparent.
A Symphony of Servers: Inside the Data Center
The first impression is a powerful hum of ventilation. Orange cables snake across the ceiling, leading the eye through corridors to the electricity arrival and control rooms, deliberately isolated due to fire risks. Grégory Lebourg, director of environmental programs, noted that lessons learned from a 2021 fire at a Strasbourg data center have led to notable changes. “Having experienced a lightning strike, we are necessarily more sensitive,” Lebourg said, alluding to the incident.
Since the fire, the company has invested €60 million in a “hyper-resilience plan” to prevent future incidents, according to Solange Viegas Dos Reis, the group’s legal director. Viegas Dos Reis added that insurance companies are now eager to work with OVHcloud, a stark contrast to the situation in 2021 when “no company wanted to insure us.”
Beyond the security checkpoints lies the heart of the data center. Instead of rows of refrigerated cabinets, long aisles of “bays” fill the space, servers stacked within metal structures reaching several meters high. Antoine Renaut, regional manager of data centers, estimates that each square meter houses between 25 and 60 servers.

Water Cooling: An Innovative Approach
Inside the data center, a network of yellow, black, red, blue, white, and green cables connects the servers. Copper pipes carrying cold and hot water are also present, highlighting OVHcloud’s unique cooling system.
OVHcloud’s water-cooling system, developed in 2003, sets it apart. “We are independent of the outside temperature,” Lebourg stated.Unlike competitors who rely on air conditioning, ovhcloud uses water to cool its servers, a system protected by hundreds of patents. The water-cooling system removes approximately 70% of the heat emitted by the servers.
The system circulates water through an exchanger placed above the processor, capturing heat that is then released outside, sometimes reused. This approach reduces the need for energy-intensive air conditioning,resulting in significant savings and environmental benefits,allowing OVHcloud to compete with larger American ”hyperscalers” like AWS,azure,and Google Cloud,according to Lebourg.
from Factory to Data Center: A Vertically Integrated Approach
OVHcloud designs and assembles its servers in its own factory, located a few kilometers from the data center. A similar factory exists in canada to serve North America.Inside the factory, workers assemble components onto metal frames, creating servers from parts sourced globally.
Employees undergo training to assemble the servers, a process that resembles “LEGO assembly.” Frédéric Lockart, who oversees the workshop and recycling operations, noted that a server is produced approximately every three minutes. Servers have a lifespan of up to nine years, with performance cycles of three years. Older servers are still viable for customers who do not require the latest technology.
At the end of their lifespan,servers are dismantled,with 60% of the components recycled. Some parts are reused, while others are sold to brokers. Unusable components are crushed.

Securing Sensitive Data
Roubaix 8 houses SNC (SecnumCloud) rooms, also known as “Critical +,” with restricted access. These rooms provide the highest level of cybersecurity, protecting stored data from extraterritorial laws. this certification is increasingly required for sensitive state data.
Viegas Dos Reis emphasized that OVHcloud’s independence stems from manufacturing its own servers and operating its own telecom networks. She added that the company’s ownership structure, with 80% still held by the family of founder Octave Klaba, further contributes to its sovereignty.
viegas Dos Reis noted an increase in customer interest due to concerns about the dominance of American cloud providers. “We now host the IGN and the CNRS,” she said. She believes that OVHcloud’s commitment to sovereignty is a key differentiator. “Being at OVH is good,because we are sovereign,” Viegas Dos Reis stated.She added that sovereignty is now a priority for business leaders, not just IT departments.
While the decision to switch to a European cloud provider can take months or years, OVHcloud hopes to capitalize on the growing demand for sovereign cloud solutions.
As the doors close on the ovhcloud facility, the work continues. Servers are assembled, tested, and recycled, while outside, life on Kellermann Street continues, unaware of the activity within the Roubaix 8 data center.

Inside OVHcloud’s Roubaix Data Center: Your Questions Answered on European Cloud Sovereignty
The digital world runs on data. But where does that data live? And who controls it? In an era of increasing digital dependence and geopolitical uncertainty, the concept of a “sovereign cloud” is gaining traction. Let’s take a deep dive into the heart of OVHcloud’s operations in Roubaix, France, to understand what European cloud sovereignty really means.
What is OVHcloud and Why Is It Critically important?
OVHcloud is a leading european cloud provider offering a range of cloud services, including hosting, compute, and storage. It’s a critically important player in the global cloud market, particularly for businesses and organizations seeking a European-based cloud solution. Its importance stems from its commitment to data sovereignty, which means keeping data within European borders and under european laws.
What Does “European Cloud Sovereignty” Mean?
European cloud sovereignty refers to the practice of keeping data stored and processed within the borders of the European Union, subject to EU laws and regulations.
