Microsoft (MSFT) and Amazon Face EU Digital Markets Act Scrutiny Over Cloud Dominance

Key Takeaways

• The European Commission may reveal next week that Microsoft Azure and Amazon Web Services meet the threshold for Digital Markets Act regulation.
• A conclusive determination is anticipated by the close of 2025, although the schedule remains flexible.
• Upon formal classification, both platforms must comply with requirements regarding interoperability, preventing vendor lock-in, and eliminating preferential treatment of proprietary services.
• This investigation stems from a November 2024 EU declaration recognizing both corporations maintain “exceptionally dominant market positions” in cloud infrastructure.
• Multiple significant service disruptions affecting AWS and Azure have intensified regulatory focus on the sector.

The European Union is advancing toward subjecting Microsoft’s Azure and Amazon Web Services to regulatory oversight through its Digital Markets Act legislation. Bloomberg reports the European Commission may unveil its initial assessment within the coming week.

The DMA framework specifically addresses major digital platforms that possess what European authorities characterize as “gatekeeper” market influence. Should Azure and AWS receive official gatekeeper status, they’ll be obligated to adhere to regulations crafted to ensure competitive fairness.

Implications of Gatekeeper Classification

Once designated under the DMA, both cloud platforms must satisfy interoperability standards. Additionally, they’ll encounter limitations designed to eliminate practices that trap customers within their ecosystems and prohibit giving preferential treatment to their own offerings over competitor alternatives.

Regulators expect to finalize their determination before 2025 concludes. Nevertheless, individuals with knowledge of the proceedings indicate the timeline remains subject to adjustment.

The examination began in November 2024 following the European Commission’s acknowledgment that Microsoft and Amazon maintain exceptionally strong market positions within cloud computing. This declaration initiated the official investigation process.

European lawmakers established the DMA to combat monopolistic practices among dominant technology companies operating across the continent. The legislation has previously been enforced against corporations including Apple and Google in different technology sectors.

Service Disruptions Intensify Regulatory Pressure

Regulatory attention on these cloud infrastructure leaders has intensified following several prominent service failures. AWS experienced an extended outage lasting approximately 15 hours that affected major clients including Apple, McDonald’s, and Epic Games. A distinct Azure disruption in October disabled Alaska Airlines’ passenger check-in infrastructure and interrupted legislative operations at the Scottish Parliament.

These technical failures highlighted the extent to which modern digital commerce relies upon a concentrated group of cloud service providers.

Both Microsoft and Amazon declined to provide statements when contacted for this report.

The Commission has yet to release its official assessment publicly. Should the initial conclusions remain unchanged, both organizations will receive an opportunity to submit responses prior to any binding determination.

Cloud computing infrastructure has emerged as a priority surveillance area for EU regulatory bodies, reflecting the sector’s rapid expansion and the extensive number of enterprises dependent upon these platforms.

This probe represents one component of the EU’s comprehensive effort to enforce competition standards across the largest operators in digital infrastructure services.
