At first glance, cloud computing looks like a technical service: compute, storage, or software delivered over the internet. In practice, cloud infrastructure now carries core processes of business and government, from data storage to AI training to security architectures. That makes cloud more than an IT topic. It is a strategic factor for economic and political agency.
This is where digital sovereignty comes in. It means the ability of states, companies, and institutions to stay self-determined even in a globally connected economy. That doesn't mean cutting yourself off from the global ecosystem. It means keeping room to maneuver of your own, especially when geopolitical tensions arise.
A few providers, structural dependencies
The market is shaped by a handful of large providers, such as Amazon Web Services, Google Cloud, and Microsoft Azure. They pool enormous economies of scale and deliver not just infrastructure but whole ecosystems of developer tools, data platforms, and AI services. That's attractive for companies, but it creates dependencies. Part of this is legal: data held by US providers may sit in European data centers but is additionally subject to US law, so US authorities can under certain circumstances gain access. Market power, technical infrastructure, and legal access end up coinciding.
Lock-in through integration and data gravity
Dependency also arises technically. If you build applications, data structures, or AI models on a particular cloud architecture, you adapt to its interfaces, services, and proprietary standards. That makes innovation and scaling easier but a later switch harder. Then there's so-called data gravity: compute tends to follow the data. Once large amounts of data sit on one platform, analytics and AI workflows get built there too, and changing providers turns into a major IT project.
Multicloud, open standards, and open source
Many organizations therefore rely on multicloud or hybrid architectures so applications aren't permanently tied to a single platform. Open standards for data formats and interfaces help applications run across systems. Open source can also reduce reliance on proprietary systems, since the code is transparent and can be developed further on your own. But new dependencies appear when key projects are funded or steered by only a few players. Open code alone doesn't create sovereignty.
There are first attempts to make sovereignty measurable. The Digital Sovereignty Index rates things like self-operated infrastructure and open technologies. In the latest evaluation, Finland leads with about 64.5 points, and Germany follows with around 53.
Regulation alone isn't enough
In Europe, digital sovereignty is often discussed through regulation, such as the AI Act, the Data Act, or new security requirements. Such rules set important frameworks, but they don't replace infrastructure of your own. Sovereignty emerges when you produce relevant technology yourself and help shape the infrastructure. Europe brings strong industrial cores, research capacity, and a large single market to the table.
The challenge is to think regulation, innovation, and infrastructure together: building European data center and cloud capacity, investing in AI and digital infrastructure, and regulating in a way that fosters competition. Sovereignty isn't a state you fully reach or lose. It comes from the interplay of technological skill, economic strength, and political design.
For your company, that means a cloud strategy is about far more than cost and scalability. If you build data, applications, and AI systems on particular platforms, you lock in long-term dependencies. The question isn't whether Europe can become fully independent from global providers. What matters is whether its own capabilities and infrastructure grow strong enough that cooperation remains possible from a position of real agency.
