Key Takeaways

  • The European Commission is advancing plans to classify Amazon Web Services and Microsoft Azure as gatekeepers under the Digital Markets Act.
  • The designation could reshape cloud competition in Europe by targeting data portability, interoperability, and bundling practices.
  • AWS and Microsoft both contest the move, with Microsoft pointing to Google Cloud’s absence and AWS warning of potential impacts on investment.

The European Commission’s recommendation to designate Amazon Web Services and Microsoft Azure as gatekeepers under the EU Digital Markets Act arrives as the region's cloud market rapidly expands. The concentration of market power around a small group of providers has pressured regulators to intervene, introducing the possibility of binding obligations for essential digital infrastructure.

These services power how enterprises across Europe run applications, manage data, and build digital operations. According to IDC, spending on public cloud services in Europe is projected to surpass $200 billion by 2027. That forecast explains why the Commission considers the sector strategically sensitive. Hyperscale adoption has accelerated, and enterprises often consolidate workloads on a small number of large providers. Regulators remain focused on ensuring these foundational platforms do not introduce obstacles that hinder competition.

The Commission’s 2025 market investigations into cloud computing laid the groundwork for this recommendation. Those probes examined whether AWS and Azure serve as critical gateways between businesses and end users. Investigators also assessed whether the current DMA rules, originally tailored to consumer-facing digital services, adequately cover the distinct dynamics of cloud infrastructure.

From a market share perspective, structural concerns persist. Synergy Research Group estimates that AWS, Microsoft Azure, and Google Cloud collectively hold roughly 70% of the European cloud infrastructure market. That concentration has drawn scrutiny for several years, but renewed enforcement interest is tied to the rise of AI workloads. The Commission aims to ensure that platforms dominating AI training and deployment do not create unfair lock-in by design or default.

A gatekeeper designation under the DMA would add cloud computing to the list of core platform services subject to obligations on interoperability, data access, contract structuring, and anti-tying restrictions. In practice, regulatory oversight would target egress fees, cloud credits, preferential bundling with enterprise software suites, and conditions that make multi-cloud strategies expensive or difficult. While some enterprises report tangible lock-in effects, others accept the trade-offs for the performance and integration advantages of larger platforms. The Commission expects DMA enforcement to clarify allowable practices.

The policy environment around cloud sovereignty is concurrently shifting in Europe. The proposed EU Cloud and AI Development Act aims to limit dependency on non-European hyperscalers in sensitive industries like finance and healthcare. Although that initiative operates separately from the DMA, the two frameworks are complementary. Sovereignty requirements in public procurement are expected to emerge, and regulatory pressure for interoperability could encourage competition from regional providers.

AWS and Microsoft have voiced objections to the regulatory moves. Amazon published a policy blog arguing that the DMA was never intended for cloud computing, adding that the Commission’s preliminary findings overlook the diversity of services available in Europe. An Amazon Web Services spokesperson reinforced that message, stating that the findings risk discouraging European investment and innovation. The company pointed out that the region already regulates the cloud sector through the Data Act, which establishes rules on data portability and interoperability.

Microsoft’s response emphasizes concerns regarding Google Cloud's absence from the gatekeeper designation. According to Microsoft, omitting Google Cloud and Google’s Gemini AI platform could unintentionally tilt the competitive landscape. This argument centers on whether enforcement evenly captures all major providers in the ecosystem.

Geopolitical tensions further complicate the regulatory proceedings. The Trump administration has repeatedly framed European tech regulation as an attack on American companies. Placing AWS and Microsoft Azure on the gatekeeper list adds to existing trade frictions, though European policymakers remain focused on structural market dynamics.

The Commission is conducting a separate procedure to determine whether the DMA checklist is suitable for cloud computing. The DMA’s original structure targets consumer-facing digital services, while cloud infrastructure introduces distinct characteristics, from infrastructure layering to enterprise-specific procurement cycles. The Commission expects to deliver related recommendations by May 2027, indicating continued evolution of the regulatory framework.

Analysts are monitoring these regulatory developments closely. Reports from Bloomberg highlight how the gatekeeper designation could affect egress pricing and AI development partnerships. Industry researchers note that large enterprises are reevaluating cloud resilience and vendor diversity as regulations shift. IT leaders are exploring nuanced hybrid strategies to balance compliance risks with the compelling economics of hyperscale providers.

In the security domain, ENISA’s certification schemes continue to play a central role. These standards guide compliance expectations for hyperscale cloud platforms and could influence responses to future DMA obligations. If interoperability requirements align with ENISA frameworks, providers may consolidate compliance across multiple regimes to manage the administrative workload.

Enterprise buyers are evaluating how new regulatory obligations for AWS and Microsoft Azure will alter multi-year cloud strategies. Changes to pricing or data portability will directly impact infrastructure planning. Organizations in industries with heavy regulatory oversight are actively modeling the potential impacts on architecture and vendor selection to ensure long-term flexibility.

While the designation remains a recommendation, Europe is preparing to treat hyperscale cloud services as a critical infrastructure layer requiring strict regulatory oversight. Market participants are assessing whether the DMA interventions will effectively accelerate competition or introduce new operational friction across the digital ecosystem.
