The European Union is making a significant move towards digital sovereignty. EU member states are now officially requiring high-risk AI systems and strategic data to be stored exclusively on cloud platforms certified as resistant to external influence. However, a key challenge remains: there is still no consensus on the precise definition of a “sovereign cloud.”
Europe Wants Its Data Back—But What’s a Sovereign Cloud?
Protecting Europe’s Most Sensitive Systems
EU governments want super-risky AI, especially stuff affecting health, safety, or basic rights, to run only on EU-run cloud servers, according to a Council doc from April 25th. This is all about dodging manipulation or spying from outside Europe.
Basically, these important apps should be on clouds with EU approval. They’re setting things up for new EU laws on AI and cloud security, planned for 2026.
France is already moving 30 million health records off Microsoft Azure to a European cloud, worried US laws might let American agencies get at that data.
More Than Just Cybersecurity
Just doing cybersecurity isn’t enough for Europe anymore. Political resilience is now key, especially in talks about cloud security rules (EUCS). It’s about keeping European data safe from outside laws, like US ones that might let American agencies grab data even if it’s on servers in Europe.
Even though no one totally agrees on what a “sovereign cloud” is, it’s becoming clear it’s more than just tech – it’s about who’s in control and having legal freedom.
Also, most cloud stuff is in a few big cities like Frankfurt, Amsterdam, Paris, and Dublin, which leaves other parts of Europe behind. To fix this, they might give tax breaks and funding for data centers in less developed areas.
The American Cloud Oligopoly
Basically, US tech giants run the cloud market right now. European companies’ share has shrunk a lot, while Amazon, Google, and Microsoft own over 70% of the EU market. France’s OVHcloud and German companies SAP and Deutsche Telekom have tiny shares. The EU wants to cut back on relying on these US firms but admits they’re also key for building stuff here.
Green Cloud? Not So Simple
There’s also a climate issue. EU reports show that the average data center guzzles 26 million liters of water per megawatt yearly. Right now, the EU has 1,240 data centers using 8.3 gigawatts, and that’s going up to 13 GW by 2027.
That much energy and water use clashes with the EU’s climate goals. Plus, they use PFAS chemicals in cooling, which makes things trickier.
The EU wants “super green” data centers, but nobody knows what that really means yet. They haven’t decided on any actual standards for being sustainable.
Bureaucracy: The Hidden Bottleneck
Building data centers in Europe takes ages—over 20 months for approvals, and sometimes years more thanks to supply issues or chip checks, especially for AI elements.
The EU’s trying to speed things up with permits, especially environmental ones, but they’re worried it might hurt green goals. To really make it work, everyone in government needs to be on the same page to avoid chaos.
Right now, Europe doesn’t have a huge AI training center like the US and China are building. Some big new projects might change that, but the EU needs a solid plan and faster investment.
Why It Matters?
Digital sovereignty isn’t just a political buzzword anymore. It’s becoming a requirement for defending Europe’s values—privacy, freedom, and open competition.
But without a clear and coordinated EU strategy, including robust cloud certification, fair infrastructure distribution, green standards, and faster permitting, digital sovereignty risks becoming just another empty slogan.
For young Europeans, this moment is crucial. The digital systems we build (or fail to build) today will define your future access to knowledge, innovation, and rights in an increasingly connected—and contested—world.
