European Union antitrust authorities have taken a decisive step to expand their oversight of Big Tech by formally proposing that Amazon Web Services and Microsoft Azure be classified as gatekeepers under the bloc's landmark Digital Markets Act. The designation follows an intensive seven-month investigation into cloud computing services and signals the EU's determination to regulate critical digital infrastructure beyond traditional platforms like search engines and social networks. This move represents a watershed moment in global tech regulation, as Brussels widens its enforcement arsenal into cloud services widely recognised as essential to artificial intelligence development and deployment across the continent.
The regulatory framework under which this decision sits was designed to curb the market dominance of technology giants by imposing binding obligations on companies deemed to control key digital gateways. Should the preliminary findings become final, both Amazon Web Services and Microsoft Azure would face a comprehensive set of restrictions aimed at preventing anti-competitive practices. These constraints would include prohibitions on self-preferencing—a practice where platforms favour their own services over competitors—alongside mandatory requirements for interoperability between systems and seamless data portability for users wishing to switch providers. The stringency of these measures underscores Brussels' conviction that cloud infrastructure has become so economically significant that competitive safeguards are now imperative.
EU technology chief Henna Virkkunen contextualised the decision within a broader strategic framework, emphasising that cloud services have matured into fundamental economic infrastructure across Europe. Her statement highlighted that over half of all EU businesses now depend on cloud platforms, while investment in public cloud infrastructure has reached record levels. This proliferation of dependence creates what regulators view as a structural vulnerability—where concentrated market power in cloud provision could translate into outsized influence over European digital competitiveness and technological sovereignty. For Virkkunen and her counterparts, the designation represents a necessary intervention to ensure that markets remain contestable and that smaller providers retain realistic pathways to competition rather than facing insurmountable barriers to entry.
The reasoning behind targeting these two specific companies reveals how EU regulators assess market dominance in the cloud sector. Commission investigators identified Amazon Web Services and Microsoft Azure as possessing significantly larger revenues, operational capacity and research investment than competing services. Crucially, both have cultivated extensive and deeply embedded user bases characterised by substantial switching costs and lock-in effects—conditions that make it extremely difficult for customers to migrate to alternatives even if they wished to do so. Additionally, the regulators highlighted the growing integration of artificial intelligence capabilities and exclusive partnerships within the cloud offerings from both companies, treating these bundled services as a decisive factor influencing procurement decisions among enterprise customers seeking comprehensive solutions.
Amazon Web Services responded swiftly to the preliminary assessment, characterising it as fundamentally misguided and economically counterproductive for Europe. The company's statement emphasised the diversity of cloud options available to European customers, arguing that the regulator's analysis downplayed genuine competition in the sector. AWS further contended that Europe already possesses adequate regulatory oversight of cloud services through the Data Act, and that imposing an additional regulatory layer through the Digital Markets Act would constitute excessive and overlapping compliance burdens. The company warned that such regulation risks discouraging European investment and innovation, potentially pushing technology development and capital allocation away from the continent to more regulatory-friendly jurisdictions.
Microsoft adopted a different defensive posture by redirecting scrutiny toward its rival Google. The software giant expressed concern that EU regulators had overlooked Google Cloud's expanding market presence and the competitive advantages conferred by integration with Google's Gemini artificial intelligence systems. By highlighting Google's growing influence in cloud provision, Microsoft sought to reframe the regulatory debate as incompletely addressing the actual competitive landscape. This counterargument reflects a broader strategy among major tech companies facing regulation to argue that enforcement agencies have misidentified which competitors pose the greatest market threats and that selective enforcement tilts competitive dynamics in unintended directions.
The designation process now enters a crucial phase in which both Amazon and Microsoft can formally respond to the Commission's preliminary findings before regulators issue their final determination. This period allows companies to submit evidence and arguments challenging the evidentiary basis for the gatekeeper classification, dispute the legal interpretation of relevant market dynamics, or demonstrate that the proposed remedies would impose disproportionate costs. The timeline for a final decision remains open, though EU authorities have indicated a resolution within coming months rather than an indefinite delay.
For Malaysian and Southeast Asian technology businesses, this regulatory development carries significant implications. Many regional companies rely on AWS and Azure for cloud infrastructure, and any obligations imposed by the EU could ripple through global service standards and pricing. The gatekeeper designation may force these platforms to implement additional compliance systems and potentially restructure service offerings or partnership arrangements to satisfy European requirements. Such changes could either increase costs for users globally or alter competitive dynamics in ways that benefit or disadvantage different categories of customers depending on how remedies are designed. Southeast Asian enterprises should monitor the final ruling closely, as it may establish precedents that influence how other jurisdictions approach cloud regulation in coming years.
