Sovereign cloud: what it really means for a business

“Sovereign cloud” is one of the most used expressions of recent years, and also one of the most misunderstood. Some reduce it to “servers in my country”, others see it as a matter for governments and large public bodies. In reality it concerns any company that entrusts important data to the cloud: data about customers, employees and projects.

Let’s clear things up, without jargon.

The core question: who decides about my data?

A sovereign cloud answers three very concrete questions:

1. Where is my data physically stored?
2. Which laws apply to that data, and which authorities can request access to it?
3. Who really controls the infrastructure, the encryption keys and the access?

A cloud is sovereign when the answers are clear and consistent with the company’s choices: the data stays in the chosen jurisdiction, it is subject to that jurisdiction’s laws, and control remains in the customer’s hands.

Why server location is not enough

Keeping data in a European data center is necessary, but not always sufficient. The law the provider is subject to matters too. Some non-European regulations, such as the US CLOUD Act of 2018, allow the authorities of those countries to ask domestic providers for access to the data they manage, even when it is stored abroad.

That is why a sovereign approach looks at three levels:

• data sovereignty: where data is stored and processed;
• operational sovereignty: who runs the infrastructure, from where and with which controls;
• technological sovereignty: the ability to change provider without being locked into technologies or contracts.

What European regulations require

No law forces every company to use a “sovereign cloud”. But several regulations turn the choice of infrastructure into a decision with precise consequences.

• GDPR (EU Regulation 2016/679): whoever processes personal data must know where it ends up, ensure appropriate security measures and carefully assess transfers to countries outside the EU.
• NIS2 (EU Directive 2022/2555), transposed into national law in every member state: for the organizations within its scope, supply chain security, cloud included, becomes an obligation, and management bodies are directly accountable.
• Data Act (EU Regulation 2023/2854), applicable since September 2025: it introduces rules that make it easier and cheaper to switch cloud providers, limiting technical and contractual lock-in.
• AI Act (EU Regulation 2024/1689): for those using artificial intelligence, governing the data used to train and run models becomes part of risk management.

The common message is clear: a company must know where its data is and be able to prove it has protected it.

Sovereign does not mean closed

A common fear is that “sovereign” means giving up performance or features. It does not. A modern sovereign cloud offers the same possibilities as a large public cloud: scalable resources, private networks, automation, GPU computing for artificial intelligence.

In fact, it often offers something more:

• people close to you, who speak your language and know your market;
• lower latency, because the infrastructure is close to users and offices;
• more predictable costs and clearer contracts;
• less dependence on a single global provider.

How to evaluate a provider: the questions to ask

1. In which data centers will my data be stored, and can I choose them?
2. Which jurisdiction is the company running the service subject to?
3. Are customers’ networks and resources isolated from each other?
4. Who can access the infrastructure, and are activities logged?
5. Which security certifications do the data centers hold?
6. If I wanted to change provider one day, how would I get my data back, and at what cost?
7. What is the SLA, and what happens if it is not met?

In short

A sovereign cloud is neither a slogan nor a luxury for the few. It is a way of choosing infrastructure that starts from a simple question: who decides about my data? If the answer is “my company”, you are on the right track.
