Digital transformation of organizations today relies on ever more complex and critical systems. In this context, the digital infrastructure becomes a strategic asset, at the heart of performance, security and compliance challenges. Digital sovereignty now imposes itself as a central objective for companies and administrations that want to regain control of their data and technological choices.
Building a sovereign IT infrastructure does not mean giving up innovation, but making controlled, sustainable choices that align with the values of Open Source. This article presents the key issues, possible technological directions and best practices for designing a robust and lasting infrastructure.
What is a sovereign digital infrastructure?
A sovereign digital infrastructure denotes a coherent set of hardware, software and organisational resources that enable an organisation to retain full control over its IT infrastructure, its data and its flows. It aims to reduce dependence on proprietary solutions and to guarantee long‑term technological independence.
This approach is based on open, auditable and interoperable architectures that can evolve without jeopardising the foundations of the information system.
The key challenges of digital sovereignty
Mastery and protection of data
Digital sovereignty entails strict control over the location, access and processing of data. A sovereign digital infrastructure allows organisations to meet regulatory requirements while strengthening the security and confidentiality of critical information.
Technological independence
Relying on Open Source solutions and a Infrastructure‑as‑a‑Service (IaaS) limits vendor lock‑in. This approach fosters better mastery of IT architecture choices, while preserving the flexibility needed to support evolving business needs.
Resilience and business continuity
A sovereign infrastructure enhances the overall resilience of the information system. By using controlled architectures and proven solutions, organisations improve their ability to ensure service continuity even in the event of a major incident.
Structuring technological choices
Open Source as the foundation of the infrastructure
Open Source is the cornerstone of modern sovereign infrastructures. It guarantees transparency of internal mechanisms, facilitates security audits and promotes interoperability. Technologies such as OpenStack enable the construction of sovereign cloud environments that meet security and compliance constraints.
Private cloud, On‑Premise and hybridisation
A sovereign cloud can take several forms according to needs: private cloud, On‑Premise infrastructure or hybrid architecture. The choice depends on the required level of control, regulatory constraints and performance requirements. In every case, mastery of the IT architecture remains a key factor of sovereignty.
Containerisation and standardisation
Containerisation contributes to modernising sovereign infrastructures by easing application portability and deployment automation. Orchestration solutions like Kubernetes fit perfectly into an Open Source‑driven strategy focused on performance and control.
Best practices for a sovereign infrastructure
Design a modular architecture
A sovereign IT architecture must be modular, scalable and interoperable. This approach allows the infrastructure to adapt to technological changes without relying on a single vendor.
Establish clear IT governance
Governance plays a central role in the durability of the IT infrastructure. It includes access management, security policies, documentation of technical decisions and continuous monitoring of environments.
Rely on expertise and support
Implementing and operating a sovereign digital infrastructure requires expert assistance. LINAGORA’s Open Source services cover the entire lifecycle of the infrastructure, from consultancy to operation, including deployment and technical support.
Conclusion
Building a sovereign digital infrastructure is a strategic initiative that reconciles performance, security and technological independence. By combining Open Source, sovereign cloud, rigorous governance and domain expertise, organisations obtain a solid foundation to support their digital transformation.
This vision of the IT infrastructure turns the information system into a true value lever, capable of evolving sustainably while remaining fully under control.
