European antitrust authorities have taken a decisive step to regulate cloud computing by formally designating Amazon Web Services and Microsoft Azure as 'gatekeepers' under the Digital Markets Act, bringing the world's two largest cloud service providers into the scope of the bloc's landmark technology regulations. The decision, unveiled in Brussels, represents a significant departure from earlier regulatory efforts that primarily targeted consumer-facing platforms such as search engines, social networks, and app stores, extending the regulatory framework deeper into the infrastructure layer that underpins the European digital economy.
The gatekeeper designation carries substantial regulatory consequences for both companies. Under the DMA framework, AWS and Azure would face binding obligations restricting self-preferencing practices—a concern centred on whether these providers give preferential treatment to their own AI tools and services over competing offerings. The companies would also be required to enhance data portability and ensure technical interoperability with rival services, allowing customers to migrate between providers more easily. These measures are designed to address concerns that the market power wielded by these cloud giants has created significant barriers to competition and locked customers into their ecosystems.
The designation emerged following a comprehensive seven-month investigation by the Commission, during which authorities examined the structural advantages and market dynamics within Europe's cloud computing sector. Regulators concluded that AWS and Microsoft Azure possess insurmountable competitive advantages, including significantly higher revenues, greater operational capacity, substantially larger investments in infrastructure, and entrenched customer bases that experience considerable switching costs. The findings highlighted how these two providers have systematically expanded their market positions across multiple layers of cloud services and related AI capabilities.
EU tech chief Henna Virkkunen emphasised the strategic importance of regulating cloud infrastructure, noting that over half of European businesses now depend on cloud services and that cloud computing has become essential infrastructure for artificial intelligence development. Her statement underscores Brussels' determination to ensure that critical digital infrastructure operates within competitive parameters rather than remaining concentrated in the hands of a handful of American technology giants. The framing reflects broader European concerns about technological sovereignty and the continent's ability to develop competitive advantages in artificial intelligence without dependence on controlled infrastructure.
The expansion into cloud regulation marks a crucial evolution in EU tech policy, signalling that antitrust authorities are prepared to intervene across the entire technology stack, not merely at consumer-facing layers. This approach recognises that competitive dynamics at the infrastructure level directly influence which companies can compete in higher-value services, including emerging AI applications. The move also reflects growing awareness that cloud computing gatekeepers exert disproportionate influence over technological development and innovation patterns across the European digital economy.
Amazon's response challenged the regulatory logic, arguing that the cloud services market is already sufficiently diverse and that European customers have access to a broad array of alternatives. The company contended that the DMA designation ignores existing regulatory frameworks, particularly the recently implemented Data Act, and that layering additional obligations under the DMA would impose redundant compliance burdens that ultimately deter investment and innovation in European cloud infrastructure. AWS specifically criticised the regulatory approach as potentially undermining European competitiveness by creating barriers to adopting cutting-edge technology services.
Microsoft adopted a different defensive posture, pivoting attention toward Google Cloud's expanding competitive threat. The company raised concerns that regulators had overlooked Google's growing power in cloud services and its advancing artificial intelligence capabilities through Gemini, arguing that failing to address Google's trajectory would create perverse market incentives that harm overall competition. This counter-argument attempts to reframe the regulatory debate by suggesting that singling out Microsoft and Amazon creates relative competitive advantage for other players rather than promoting balanced competition.
Regulators justified their targeting of AWS and Microsoft by emphasising that their AI tools and strategic partnerships have become decisive factors influencing cloud procurement decisions across Europe. This observation points to a critical market dynamic: large enterprises and government agencies increasingly view cloud provider selection as an AI acquisition decision, with AWS and Azure's proprietary artificial intelligence offerings and partnerships acting as powerful draws regardless of alternative providers' technical capabilities. The Commission's analysis suggests that competitive considerations increasingly occur at the intersection of cloud infrastructure and AI, requiring regulatory intervention at that nexus.
The pathway forward remains uncertain as both companies now have opportunities to challenge the Commission's preliminary findings through formal responses before the regulator issues a final decision in coming months. These counter-submissions will likely feature detailed economic analysis, competitive market data, and arguments about regulatory overreach. The eventual outcome carries implications extending far beyond Amazon and Microsoft, effectively establishing whether the DMA framework applies comprehensively across all layers of digital infrastructure or whether cloud services warrant different regulatory treatment based on their foundational importance to the broader digital economy.
For Asian technology companies and businesses relying on European cloud infrastructure, these developments signal increased regulatory scrutiny and potential compliance obligations for any service providers that eventually gain substantial market power within EU borders. The regulatory approach adopted here may also influence how other jurisdictions, including Southeast Asian economies, approach cloud services regulation in their own markets. Moreover, the extension of DMA obligations to infrastructure services may accelerate the development of European alternative cloud providers, potentially creating opportunities for regional technology firms to serve European customers seeking to reduce concentration risk.
The broader implication of this decision reflects a fundamental shift in how the European Union approaches technology regulation. Rather than limiting intervention to obvious consumer-facing platforms where harms are immediately visible, Brussels is intervening at infrastructure layers critical to future competitive dynamics. This proactive approach acknowledges that regulatory action limited to downstream applications cannot effectively address market power concentrated in foundational technologies, particularly in infrastructure services that influence artificial intelligence development trajectories across the continent.
