Ofcom says AWS, Azure, and Google may be limiting competition in the UK cloud computing market after a review since October 2022 and refers the case to the CMA
Amazon.com Inc. and Microsoft Corp.'s cloud services could face a full-blown antitrust probe in the UK after the country's digital regulator …
Context & Ripple Effects
Ofcom had already signaled that cloud computing would be part of a wider competition review, through its planned examination of cloud, messaging, and smart-device markets. This referral turns that preliminary scrutiny into a competition matter for the CMA.
The case centers on the market power of AWS, Azure, and Google rather than a single product dispute. Related coverage later records the CMA's formal public-cloud investigation, making this referral the handoff point between sector review and antitrust enforcement.
First-order effects
- AWS, Microsoft Azure, and Google face CMA scrutiny in the UK, adding regulatory risk to the terms and practices used to sell public-cloud services.
- UK cloud customers gain a formal competition channel for concerns about provider conduct, while Ofcom transfers the case from its market review to the CMA.
Second-order effects
- A CMA investigation pressures the largest providers to defend how their commercial arrangements affect customer choice; smaller cloud providers may gain a more prominent role in the competitive assessment.
- Enterprise cloud buyers may reassess the practical costs of changing providers as the investigation focuses attention on whether competition is working across the market.
Third-order effects
- The referral tests whether public cloud should be treated as a concentrated infrastructure market subject to sustained competition oversight, rather than as a software market governed chiefly by product innovation.
- If regulators find barriers to effective competition, cloud contracts and switching conditions could become a recurring antitrust focus as compute becomes more strategically important.
The trend: Cloud infrastructure is becoming a core competition-policy target as a small group of hyperscalers anchors more business computing.
