When a company controls both the infrastructure and the applications running on it, anti-competitive behavior becomes acute.
In the ongoing effort to ensure that digital power does not become unchecked dominion, the European Commission has moved to classify Amazon Web Services and Microsoft Azure as digital gatekeepers under the Digital Markets Act — a designation that would bind these cloud giants to a new layer of transparency, accountability, and constraint. The cloud, long treated as mere commercial infrastructure, is now being recognized as something closer to essential public architecture, upon which the competitive fortunes of countless businesses depend. Europe is not seeking to dismantle these companies, but to remind them that scale carries obligation, and that those who hold the keys to the digital economy must answer for how they use them.
- The European Commission is formally moving to designate Amazon Web Services and Microsoft Azure as digital gatekeepers, a classification that would impose sweeping compliance obligations on their cloud operations across Europe.
- The stakes are significant: gatekeeper status could restrict how these companies bundle services, price offerings, and use customer data — threatening business models built on the seamless integration of infrastructure and applications.
- Amazon and Microsoft together command a dominant share of the European cloud market, leaving many businesses with little practical alternative, which is precisely the dependency the Digital Markets Act was designed to disrupt.
- Fines of up to ten percent of global revenue loom for serious violations, giving the designation real teeth and signaling that Brussels intends enforcement, not merely symbolic oversight.
- The designation phase is not yet complete, but the direction is unmistakable — Europe is constructing a separate regulatory tier for the largest tech platforms, and the cloud is its newest frontier.
The European Commission has set its sights on Amazon and Microsoft's cloud divisions, moving to classify them as digital gatekeepers under the Digital Markets Act — a designation that would subject their operations to heightened scrutiny, transparency requirements, and ongoing compliance obligations.
The DMA was designed to level the playing field in digital markets by imposing strict rules on companies whose infrastructure smaller competitors depend upon. By extending this framework to cloud services, Brussels is signaling that Amazon Web Services and Microsoft Azure are not merely commercial products, but critical gateways through which European businesses access computing power and data storage. When a company controls both the infrastructure layer and the applications running on top of it, the potential for anti-competitive behavior becomes acute.
Gatekeeper status would require the companies to meet heightened transparency standards, submit to regular audits, and demonstrate that their practices do not unfairly advantage their own downstream businesses. Fines of up to ten percent of global revenue could follow serious violations. Amazon holds roughly one-third of the global cloud market; Microsoft commands a strong second position. Their combined European footprint leaves many businesses with little practical choice but to rely on one or both — precisely the dependency the DMA seeks to address.
The designation would not ban either company from offering cloud services, nor automatically restructure their operations. It would instead establish a new regulatory relationship with European authorities. For the broader market, the outcome remains uncertain: smaller cloud providers might gain breathing room, or the compliance burden could paradoxically entrench the largest players further.
The Commission has not yet issued a formal classification, but the trajectory is clear. Europe is building a distinct regulatory regime for its most powerful digital platforms, and for Amazon and Microsoft, the question is no longer whether gatekeeper rules will apply — but how they will reshape their operations to meet them.
The European Commission has set its sights on Amazon and Microsoft's cloud divisions, moving to classify them as digital gatekeepers under the bloc's Digital Markets Act—a designation that would subject their operations to a new tier of regulatory scrutiny and compliance obligations.
The DMA, the EU's flagship legislation for policing the behavior of dominant tech platforms, was designed to level the playing field in digital markets by imposing strict rules on companies with outsized market power. The law targets firms that control essential infrastructure or services that smaller competitors depend on to reach customers. By bringing cloud services under this framework, Brussels is signaling that it views Amazon Web Services and Microsoft Azure not merely as commercial offerings, but as critical gateways through which European businesses access computing power and data storage.
The implications are substantial. Gatekeeper status would require Amazon and Microsoft to meet heightened transparency standards, submit to regular audits, and potentially face restrictions on how they bundle services, price offerings, or use data gathered from customers. The companies would need to demonstrate that their practices do not unfairly advantage their own downstream businesses or disadvantage competitors who rely on their platforms. For cloud providers operating at massive scale, these requirements translate into significant operational and compliance costs.
The move reflects a broader European strategy to rein in the market dominance of Big Tech. The DMA has already cast its net wide, targeting companies like Google, Meta, and Apple. But cloud services represent a particularly sensitive domain because they form the digital backbone of modern business. When a company controls both the infrastructure layer and the applications running on top of it, the potential for anti-competitive behavior—whether through preferential pricing, data access, or service prioritization—becomes acute.
Amazon Web Services holds roughly one-third of the global cloud market, while Microsoft Azure commands a significant second position. Their combined market share in Europe is substantial enough that many businesses have little practical choice but to use one or both. This dependency is precisely what the DMA seeks to address. By designating these services as gatekeepers, the Commission is asserting that the companies' market position gives them power over other businesses' ability to compete, and that power must be constrained.
The designation would not ban Amazon or Microsoft from offering cloud services, nor would it automatically break up their operations. Rather, it would establish a new regulatory relationship between the companies and European authorities. The firms would face ongoing compliance obligations, regular reporting requirements, and the threat of substantial fines—up to ten percent of global revenue for serious violations—if they breach the rules.
For the broader cloud market, gatekeeper status could reshape competitive dynamics. Smaller cloud providers and European alternatives might gain breathing room if the rules prevent dominant players from leveraging their scale in anti-competitive ways. Conversely, the compliance burden could entrench the largest players further, as smaller competitors lack the resources to navigate the same regulatory landscape. The outcome will depend heavily on how strictly the Commission enforces the rules and how the companies adapt their business models in response.
The move is still in its designation phase, meaning the Commission has not yet formally classified Amazon and Microsoft as gatekeepers. But the trajectory is clear. Europe is moving toward a model in which the largest tech platforms operate under a distinct regulatory regime, separate from ordinary commercial law. For Amazon and Microsoft, the question is no longer whether they will face gatekeeper rules, but how they will restructure their operations to comply with them.

A Conversa do Hearth Outra perspectiva sobre a história
Why does the EU care specifically about cloud services? Aren't they just another product?
Because cloud is infrastructure. When a business needs to store data or run applications, they often have no choice but to use Amazon or Microsoft. That dependency is what makes it a gatekeeper issue.
So the EU is saying these companies have too much power?
Exactly. The DMA assumes that when you control something essential that competitors depend on, you can abuse that position—by charging unfairly, favoring your own services, or blocking rivals. The rules are meant to prevent that.
What actually changes if they get designated as gatekeepers?
They'd face constant audits, transparency requirements, and restrictions on how they bundle or price services. They'd also face massive fines if they violate the rules. It's not a ban; it's a new regulatory relationship.
Does this help smaller cloud companies?
Potentially. If Amazon and Microsoft can't use their dominance to crush competitors, there's more room for alternatives. But the compliance burden is so heavy that it might actually entrench the big players further.
What's the timeline here?
The Commission is still in the designation phase. Once formally classified, the rules kick in. But this is clearly coming—the EU has already signaled its intent.
