A single hour of service disruption can cost a large company an average of $260,000. That is the conclusion reached by Aberdeen Group in 2024. The recent outages at AWS and Microsoft Azure are not just minor incidents; they are a warning sign about the vulnerability of information systems. The concentration of the global public cloud market exposes businesses to major risks in terms of business continuity and digital sovereignty.
As Sébastien Lescop, CEO of Cloud Temple, states in this article from Le Parisien : there's an urgent need to diversify infrastructures to limit exposure to outages and strengthen resilience.
More and more organizations are rethinking their strategies to build hybrid and multi-cloud architectures, balancing performance, security, compliance, and sovereignty.
Concentration of cloud providers: an operational and regulatory risk
Over the past ten years, hyperscaler suppliers (AWS, Azure, Google Cloud) have been the backbone of information systems. Centralising services and data with a limited number of players creates a number of risks:
- Vendor lock-in : Technological dependence
The use of a supplier's proprietary solutions creates a heavy dependence. Migrating to another player becomes complex and costly, sometimes almost impossible, and can even involve rewriting applications or abandoning critical functionality. - Business continuity risk: The domino effect
A widespread breakdown can paralyse thousands of critical services and millions of users simultaneously. Sales, productivity and operational capacity are directly threatened. - Regulatory exhibition: The jungle of jurisdictions
Hosting data in foreign jurisdictions complicates compliance with the RGPD, DORA and NIS2, which impose strict requirements on the location and sovereignty of data. - Economic and reputational risks : The price of unavailability
Service interruptions lead to direct financial losses, contractual penalties and an erosion of customer confidence.
These findings underline the need to adopt diversified cloud strategies, combining SecNumCloud qualified sovereign cloud, hybrid cloud and multi-cloud, to reduce dependency and strengthen the resilience of information systems.
Building digital resilience: three complementary levers
1. Multi-cloud: diversify to secure and optimise
The multi-cloud approach involves distributing workloads and data across several providers (local or international public clouds, sovereign cloud) to limit dependence on a single player.
The benefits:
- Reinforcing business continuity : automatic switchover of critical applications in the event of failure.
- Optimising performance : each workload is hosted on the most suitable service.
- Controlling costs : taking advantage of competition between suppliers.
This approach requires advanced technical governance: interoperability via Kubernetes, Terraform, OpenStack, unified security monitoring, and rigorous cost tracking. An expert integration partner is essential to orchestrate these environments.
2. The hybrid cloud: agility, control and sovereignty
The hybrid cloud combines private (on-premise), international public, and sovereign environments to balance performance, control, and security.
It allows you to :
- Storing sensitive data in controlled environments (financial, health, critical data...) via a trusted cloud.
- Exploiting the scalability of the public cloud for less sensitive workloads or peaks in activity.
- Ensuring business continuity thanks to a redundant architecture.
This approach balances innovation and control, meets the requirements of French and European regulations, and fits naturally into a multi‑cloud strategy.

3. The trusted cloud: a sovereign and secure foundation
For organizations subject to strict regulatory constraints, digital sovereignty is essential. SecNumCloud‑qualified trusted clouds guarantee:
- Data located and operated in France, outside the scope of extraterritorial laws.
- High level of security, traceability, and transparency, in line with the standards set by ANSSI (the French cybersecurity government agency).
- Legal protection through French‑based governance, offering full independence.
These environments complement the regulatory requirements of the RGPD, DORAand NIS2 to host critical applications.
