EU Proposes AWS and Azure as Digital Markets Act Gatekeepers
The European Commission has issued a preliminary finding that Microsoft’s Azure and Amazon’s AWS should be classified as “gatekeepers” under the Digital Markets Act (DMA). If finalized, this designation would force both companies to meet strict requirements regarding data interoperability and competition, or risk fines reaching 10 percent of their total worldwide turnover. While both companies currently hold gatekeeper status for other services, this move targets their foundational cloud infrastructure as essential gateways for European businesses.
Why is the European Commission targeting cloud providers?
The Commission identifies Azure and AWS as the two largest cloud providers in the European Union, serving as critical intermediaries between businesses and their customers. According to the European Commission, these services possess “vast and entrenched user bases” that create significant barriers to entry for competitors. The Commission specifically cites “lock-in effects” and high switching costs as primary reasons for the potential designation, arguing that these factors prevent a fair and open market for enterprise technology.

The DMA designation process typically relies on quantitative thresholds, such as user counts. However, the Commission is pursuing Azure and AWS despite them not meeting these specific numerical markers, highlighting a shift toward qualitative assessments of market power.
How are Microsoft and Amazon responding to the findings?
Both companies have rejected the Commission’s preliminary position, citing concerns over the impact on innovation and European competitiveness. A Microsoft spokesperson stated that the cloud sector is already “highly competitive” and warned that ignoring the expansion of rivals like Google Cloud could tilt the market in a harmful direction. Meanwhile, an AWS representative argued that the move ignores the “breadth of cloud services” available to European customers and claimed that the existing Data Act already provides sufficient regulation for the industry.
What are the consequences of a gatekeeper designation?
Should the findings be confirmed, the companies will have six months to align their business practices with DMA obligations. These obligations include requirements for greater interoperability between systems and stricter rules on how customer data is accessed and shared. This process mirrors the regulatory pressure previously applied to other Big Tech firms, such as Apple and Meta, though the cloud sector presents unique challenges regarding enterprise infrastructure and AI development.
Market Comparison: The Regulatory Divide
| Entity | Stance on DMA |
|---|---|
| Microsoft/AWS | Argue that regulation is redundant and risks stifling innovation. |
| Open Cloud Coalition | Support the finding, citing concerns over licensing and ecosystem lock-in. |
Frequently Asked Questions
What happens if Microsoft and Amazon are officially designated as gatekeepers?
They must comply with DMA obligations regarding interoperability and data access within six months or face fines of up to 10 percent of their global turnover.
Does this apply to all cloud services?
The current preliminary finding specifically names Azure and AWS. Other providers are not currently subject to this specific gatekeeper process.
Is this decision final?
No. The Commission’s position is preliminary, and both companies have the opportunity to respond before a final determination is made.
Keep an eye on the “Data Act” and how it interacts with the DMA. As the EU continues to refine its digital strategy, the overlap between these regulations will likely dictate how enterprise software is licensed and deployed in the coming years.
