The Framework

The CMA’s provisional recommendations under the Digital Markets, Competition and Consumers Act 2024 would impose specific operational restrictions on AWS and Microsoft if they are designated with strategic market status.^[1] The proposed restrictions include mandatory elimination of egress fees that currently allow providers to recoup infrastructure costs, forced technical standardization that would require U.S. companies to redesign their proprietary architectures for interoperability, and fundamental restructuring of software licensing models, particularly targeting Microsoft’s ability to integrate its software products with Azure cloud services.^[2] The CMA explicitly stated it could impose structural remedies requiring companies to divest parts of their business to “improve competition.”^[3] These restrictions would be subject to ongoing monitoring and iterative refinement, giving UK regulators permanent authority to modify U.S. cloud operations as market conditions change.^[4] The investigation has been extended to August 2025 specifically to develop more detailed restrictions on Microsoft’s licensing practices, signaling regulators’ intent to fundamentally reshape how U.S. cloud providers can package and price their services.^[5]

Implications for U.S. Technology Leadership

These operational restrictions undermine U.S. technological leadership by forcing American companies to abandon the integrated service models and economies of scale that drove their global success. The mandatory elimination of egress fees removes a standard industry practice that helps providers manage network costs and incentivizes efficient data management, while forced technical standardization requires U.S. companies to expose proprietary interfaces and architectures to competitors.^[6] The licensing restrictions specifically target the competitive advantages of vertical integration, preventing U.S. companies from offering the seamless experiences that customers value.^[7] By mandating these changes, UK regulators are not addressing market failures but rather redistributing the benefits of American innovation to less capable competitors. This precedent is particularly damaging; if other jurisdictions impose their own technical standards and operational restrictions, U.S. cloud providers will face an impossible patchwork of conflicting requirements that fragment their global platforms and destroy economies of scale.

The long-term implications extend beyond compliance costs to fundamental business model disruption. These restrictions transform cloud services from integrated platforms into commoditized components, eliminating the differentiation that justified decades of U.S. investment in cloud infrastructure. The ongoing monitoring and iterative intervention powers mean U.S. companies can never achieve regulatory certainty, as UK authorities can continuously impose new restrictions based on evolving theories of competition.^[8] This regulatory uncertainty particularly disadvantages U.S. firms that must make long-term infrastructure investments while facing the constant threat of forced architectural changes.^[9] As other countries observe the UK’s ability to extract concessions from U.S. tech leaders through competition policy, they are likely to impose similar restrictions, creating a global race to fragment and commoditize American cloud services. The result is a systematic weakening of U.S. competitive advantages in the foundational infrastructure layer of the digital economy, achieved not through superior technology or innovation but through regulatory fiat that specifically targets the features that made American cloud providers successful.
