Reinvent the Cloud Strategy
Toward Sovereign and Sustainable Digital Transformation
Guiding Principles
A modern Cloud strategy is built on three essential foundations:
• MASTERING CLOUD-NATIVE: Building robust human and technological capacity to control cloud-native environments.
• SCALING DIGITAL INFORMATION SYSTEMS: The ability to build and operate digital information systems at scale with a focus on scalability, resilience, and cost-efficiency.
• MAINTAINING A HYBRID ECOSYSTEM: Seamless integration within hybrid ecosystems (private cloud, sovereign/trusted cloud, and public cloud) to preserve flexibility, security, and performance.
Mastering Cloud-Native
Cloud mastery cannot be outsourced. It requires developing human and technological capabilities to design, operate, and secure modern cloud architectures. This is a prerequisite for ensuring sovereignty, performance, and long-term compliance.
Key focus areas:
• Resilient and scalable application and technical cloud architecture
• Advanced container orchestration
• Observability and intelligent operations via logs (SRE model)
• Automation of the development lifecycle (CI/CD, Infrastructure-as-Code)
• Mastery of open source (native, cloud features, OSS software)
• Full stack architecture: end-to-end control from datacenter to application
• Multi-cloud security framework
• Implementation of Zero Trust (ZTDA) principles
• Upskilling for key roles: AppOps, DevOps, DevSecOps, Cloud Architects
Scaling Digital Information Systems
Cloud becomes a strategic enabler when it drives a strong dynamic of digital system creation, whether through native development or legacy transformation. The goal is to industrialize innovation while maintaining high resilience and security.
Key focus areas:
• Integration of cloud roles into development teams
• State-of-the-art cloud-native application architecture (scalable, modular, resilient)
• Alignment with best cloud-native practices (Netflix-like architectures, configuration-as-code, microservices)
• Capability to quickly deliver new services to production
Maintaining a Coherent and Hybrid Ecosystem
Modern IT systems are inherently hybrid. A strong Cloud strategy must orchestrate internal cloud, public clouds, and sovereign clouds in a framework of technological continuity, unified governance, and managed reversibility.
Key focus areas:
• Internal cloud as a space for sovereignty and full-stack learning
• Technological consistency between private, public, and sovereign cloud
• Building complementary public-trusted cloud pairs
• Managing SaaS dependencies:
• Identifying strategic solutions for tight integration with information systems
• Implementing secure access to others via Zero Trust models
Mastery & Sovereignty: Key Success Factors
Success in Cloud transformation depends on the ability to:
• Build a progressive learning journey embedded in project roadmaps.
• Anticipate regulatory constraints, interoperability limits, and reversibility challenges.
• Define an enterprise-level reference Cloud stack (products, practices, orchestrators, security).
• Integrate sustainability (ESG) from design to vendor selection.
• Maintain active governance capable of steering technology decisions with agility and consistency.
Strategic principle: favor “no-regret moves” that allow progress without irreversible dependencies while maintaining adaptability to ecosystem changes.
Operating Model
A Cloud strategy is not just technical; it is embodied in a structured operational model combining:
• Clear Cloud governance led by strategic and technical bodies.
• Cross-functional Design Authorities (cloud, security, data, AI, sustainability) defining standards, best practices, and priorities.
• Value-driven investment planning based on product milestones and resource pooling.
• An integrated Build & Run model with upskilling in key roles: DevOps, SRE, DevSecOps, FinOps, etc.
This model enables industrialized Cloud adoption while ensuring flexibility, security, and strategic alignment.
