Why Europe Should Loosen Its Grip On U.S. Big Tech

During the October 20, 2025, Amazon Web Services (AWS) outage, when parts of the internet blinked off, the ripple effects were evident to everyone, from commuters asking Alexa for the weather to businesses trying to process payments. A single problem in an AWS region in the U.S. cascaded across popular apps and services worldwide before engineers resolved it. 

Technological incidents are bound to happen. Complex systems fail sometimes. But this incident didn't just affect one company; it affected the public at large, a situation that hits the nail on the head of an ongoing European debate: Are we too dependent on a few U.S. tech giants for the digital infrastructure of our daily lives and public services? The diversification to reduce single points of failure has already begun. Europe’s plan is increasingly based on open-source technologies and European options, a trend that received attention during the 2025 OpenInfra discussions.

This outage, however, was not the cause of the debate, but rather a visceral symptom of much deeper vulnerabilities. On the one hand, it provided a glimpse of how fragile digital infrastructure can be. The incident has crystallised the shift in Europe’s thinking: from a technical problem of resilience (how to survive an outage) to a core strategic challenge of sovereignty (how to control our own digital destiny). Furthermore, this outage highlighted the risk of a deliberate disruption. The October 20th outage wasn’t malicious, but a future crisis could result from geopolitics. As the U.S. and China increasingly view technology as an arena for statecraft, Europe's reliance on U.S. hyperscalers is no longer just a market convenience, but a core strategic dependency. The actual question isn't just 'What if AWS fails?' but 'What if the U.S. CLOUD Act compels data access against EU interests?' or 'What if a future administration weaponises this dependency in a trade dispute?'.

Europe is navigating a Digital Sovereignty Trilemma, attempting to optimise for three conflicting goals simultaneously:

• Strategic Autonomy: Control over its digital infrastructure, data, and legal frameworks, free from foreign statecraft.

• Economic Competitiveness: Access to the most innovative, scalable, and cost-efficient technologies (which are currently the U.S. hyperscalers') so its businesses can compete globally.

• Normative Leadership: Upholding its "human-centric" model based on fundamental rights, privacy (GDPR), and open, democratic principles.
  

The U.S. model prioritises competitiveness. The Chinese model prioritises autonomy. The EU is attempting to build a digital ecosystem that incorporates its values as a non-negotiable component. This clarifies why the challenge is so profound: Europe needs to make a fundamentally different alternative.

Who’s Already Shifting And Why 

It isn't just tech pundits. Public bodies and companies have begun shifting some of their IT operations away from U.S. platforms. In Germany's state of Schleswig-Holstein, for instance, the government recently transitioned away from Outlook to open-source alternatives as part of a broader initiative focused on digital sovereignty. 

Clear motivations drive these transitions:

• Continuity of service: The AWS outage made the risk of centralised failure visible to the public.

• Legal clarity and trust: Keeping sensitive data within European jurisdiction is easier to explain to citizens and regulators.

• Bargaining power: Less fear of being stuck because moving is too complicated or too expensive. This pressure is already working; providers started trimming data-transfer fees as the EU’s new rules began to bite.

• Geopolitical Autonomy: This is the driver that bridges the gap from resilience to sovereignty. Public bodies recognise that infrastructure controlling public data and utilities cannot be wholly subject to the laws and foreign policy of another nation. 

Europe’s Own Capacity

Two European rules are quietly changing the incentives.

1. The Data Act: This gives customers the right to switch cloud providers and forces providers to make that easy. Crucially, switching charges are on a countdown to being phased out entirely by January 12, 2027. This makes multi-cloud setups (spreading risk) less punishing for users.

2. NIS2: This EU cybersecurity law raises the baseline for essential services, pushing organisations to manage risk and report incidents more consistently.

Credible European options exist. OVHcloud, a French cloud computing company, for instance, has been expanding offerings that meet stringent French government security standards (SecNumCloud). The point isn’t that every workload should move tomorrow; it’s that having viable alternatives keeps the market honest. This is about reducing concentration risk, not ideology.

This capacity is being organised under blueprints like Gaia-X. The goal is not to build a single 'EU-AWS', but to create a federated system—a set of interoperability, trust, and data portability standards. This would allow customers to 'knit together' services from various European providers, such as OVHcloud, with the guarantee that they all meet EU standards. 

The Sovereignty Paradox: Confronting the Deeper Hurdles

While the political will is clear, the path is blocked by systemic hurdles. This creates a sovereignty paradox: the EU may have to sacrifice its global competitiveness to gain its digital autonomy. The most-discussed hurdles include:

1. The Scale: U.S. hyperscalers (Amazon, Microsoft, Google) operate at a scale almost impossible to replicate. Their R&D and capital expenditure budgets, measured in tens of billions annually, fund a relentless pace of innovation.

2. The Energy vs. Green Dilemma: A sovereign cloud requires a massive build-out of energy-intensive data centres, placing the EU's digital ambitions in direct conflict with its Green Deal objectives.

3. The Competitiveness Trap: If European sovereign alternatives are more expensive or less feature-rich, will EU businesses be forced to choose? The risk lies in selecting sovereignty (to meet EU law) at the cost of their global competitiveness.
   

Beyond these, two deeper, more fundamental hurdles exist:

4. The AI Innovation Gap: The true dependency is on large-scale generative AI models, and sovereignty over data is meaningless without sovereignty over the tools to process it. While the massive CAPEX chasm defines this innovation gap, the core challenge is Europe’s fragmented approach to closing it. The necessary financial and strategic collaboration between member states is missing. Individual national projects simply cannot compete with the consolidated R&D budgets of US hyperscalers. This failure to unify is the actual competitiveness trap, and only a more collaborative Europe can hope to keep up in the AI race.

5. The Human Infrastructure Gap: Digital sovereignty requires talent. The entire European tech ecosystem, from university curricula to developer mindshare, is overwhelmingly oriented toward U.S. hyperscaler certifications. This cultural and skills-based dependency is far "stickier" than any contract and will take a generation to reshape.

Future Short-Term Scenarios And Policy Recommendations

The future is not set. Two critical developments will likely shape it: Will the European market remain Fragmented or become truly federated and interoperable (the Gaia-X vision)? Will Europe remain a Follower or become a Global Leader in core technologies like AI?

This framework reveals four potential scenarios:

1. The Digital Colony (Low Competitiveness / Fragmented): This is the worst-case scenario. EU regulations like the Data Act and NIS2 create a complex compliance burden and bureaucracy, but fail to spur viable alternatives. The EU becomes a regulated market dominated by U.S. big tech, achieving neither sovereignty nor resilience.

2. Fortress Europa (Low Competitiveness / Federated): The EU successfully fosters local champions and the Gaia-X vision of federation works technically, but at the cost of innovation. It builds a 'digital wall' that achieves data sovereignty but isolates EU businesses from cutting-edge global AI, hampering competitiveness.

3. The Sovereign Champions (High Competitiveness / Fragmented): In this scenario, individual European companies become globally competitive, but the Gaia-X federated vision fails. Europe gains innovative firms but not a truly resilient, interoperable system. 

4. The Federated Network (High Competitiveness / Federated): The aspirational, best-case scenario. The Gaia-X vision succeeds. Interoperability becomes a genuine product. The EU creates a network of trusted, portable providers and becomes the golden standard, achieving both sovereignty and competitiveness.

   
   

This requires a three-pronged approach:

• First, leverage strategic public procurement by encouraging public bodies and essential services to prioritise interoperable, federated, and open-source solutions to create demand.

• Second, consolidate R&D investment to move beyond fragmented national projects and build foundational European models that close the innovation gap.

• Third, invest in human infrastructure by funding pan-EU certifications and university curricula that focus on the federated, open-source skills needed to build and maintain this new ecosystem.

Regulation alone is insufficient to overcome these hurdles; Europe must actively shape the market.

Conclusions

The AWS incident was a stark reminder of how fragile the current digital infrastructure is. Europe's path to greater technological independence does not require severing ties with U.S. tech giants; instead, it requires building a more resilient ecosystem with diverse options. Open-source technologies, credible European providers, and strategic regulations like the Data Act and NIS2 provide the necessary tools for this transition. Now, the key is for Europe to actively measure its dependencies, facilitate switching between providers, and consistently implement these strategies. Ultimately, resilience is cultivated through ongoing effort, not isolated events.
