The French Ministry of National Education has successfully deployed a massive open-source file-sharing platform called Nuage, now serving 400,000 active accounts among its 1.2 million employees. The project represents a significant shift toward digital sovereignty, aiming to keep sensitive student and staff data within European borders rather than relying on US-based cloud providers like Microsoft or Google.
Why France is building its own cloud
The primary driver behind Nuage is data control. Benoît Piédallu, the national project manager for digital services at the ministry, emphasized that keeping data on-premises was non-negotiable. The goal was to prevent sensitive information from being stored by external vendors in the United States.
Cost efficiency also played a major role. The ministry allocates approximately 10 euros per user annually for the project, keeping the total budget under two million euros per year. This is significantly lower than the costs associated with proprietary enterprise cloud solutions, especially when considering the scale of deployment across thousands of schools and administrative offices.
Technical architecture and infrastructure
Nuage is built on Nextcloud Files, an open-source solution developed by German vendor Nextcloud. For document editing, the platform integrates Nextcloud Office, which utilizes Collabora’s open-source software stack. The entire system runs on Linux Debian virtual machines managed internally by a small team of three staff members: two dedicated to platform management and one handling infrastructure.
The data is hosted in two state-owned data centers located near Paris and in the south of France near the Pyrenees. This dual-location setup ensures redundancy while maintaining strict geographic control over where the data resides. The ministry completed the initial deployment in 2020, with the final version released in 2022.
User adoption and storage growth
Adoption has been organic rather than forced. Without major national communication campaigns, around two-thirds of the 400,000 active users access the service weekly. Each user receives 100GB of storage, though the average usage is only about 3GB per person. Despite this low individual average, the total volume is substantial: Nuage currently stores 570 million documents amounting to 1.2 petabytes of data.
Storage demand is growing linearly, with approximately 40 terabytes of new capacity required each month. The ministry projects user numbers will reach 600,000 by the end of the year. Interestingly, officials are hoping to slow this growth slightly due to rising hardware costs and data center capacity limits, rather than accelerating it through marketing.
Challenges with office suites
While the file synchronization features have been well-received, the integrated office suite has faced some friction. Users accustomed to Microsoft Office often find the Collabora-based interface unfamiliar and lacking in specific features they rely on daily. Piédallu noted that while users are happy with the storage aspect, they still prefer the familiarity of proprietary tools for complex document editing.
Local administrations and school districts are not mandated to use Nuage. Many continue to use Microsoft SharePoint and Office tools alongside or instead of the new platform. The ministry still pays around 2.5 million euros annually for Windows licenses across 50,000 devices, indicating that a complete transition away from Microsoft is not yet complete.
What this means for you
This case study highlights the growing trend of European governments seeking alternatives to US-dominated cloud infrastructure. For everyday Windows users, it underscores the viability of open-source solutions like Nextcloud for personal or small-business file sharing if data privacy and cost are primary concerns. While the learning curve for office suites remains a hurdle, the core functionality of secure, self-hosted storage is proving robust at scale.
