The UK’s competition watchdog has recently cast a critical eye on the burgeoning cloud computing market, asserting that the formidable presence of tech giants like Microsoft and Amazon is stifling innovation and competition within the nation’s digital economy.
Following an extensive 21-month investigation, the Competition Authority (CMA) released its conclusive report, highlighting that Microsoft and Amazon Web Services (AWS) collectively command a substantial share, up to 70 percent, of the UK’s customer spending in the critical cloud infrastructure sector. This dominant position, according to the watchdog, necessitates a thorough assessment for Strategic Market Status under the UK’s progressive new digital regulations, indicating a significant moment in UK regulation.
In response, both Microsoft and AWS have vehemently rejected the CMA’s findings. A Microsoft spokesperson underscored the dynamic and fiercely competitive nature of the cloud market, emphasizing record investments and rapid advancements fueled by artificial intelligence, while also arguing that the report overlooked Google’s accelerating market growth, challenging the notion of market dominance.
Similarly, AWS contended that the regulator had dismissed compelling evidence of robust competition within the UK’s broader IT services industry, cautioning that the proposed regulatory interventions could inadvertently produce detrimental consequences for the vibrant digital landscape.
Conversely, industry leaders like Chris Lindsay, Vice President of Customer Engineering EMEA at Google Cloud, lauded the CMA’s definitive finding that restrictive licensing practices are detrimental to cloud customers and overall competition. He called for prompt intervention from the CMA’s Digital Markets Unit to ensure equitable pricing, foster greater choice, and stimulate economic growth for British businesses leveraging cloud services.
Paul Mackay, VP of Cloud at Cloudera, emphasized the opportune timing of the report, noting its release coincides with a period of rapid AI integration and escalating concerns regarding data sovereignty across Europe. This convergence of factors further underscores the urgency of addressing potential monopolistic practices in the cloud domain.
While the CMA refrained from initiating immediate investigations under the Digital Markets, Competition and Consumers Act, it has recommended prioritizing the designation of SMS status for both Microsoft and AWS in 2026, subsequent to the completion of ongoing probes into other major tech entities, Google and Apple. Attaining SMS status could subject these tech giants to legally binding conduct requirements, potentially altering their service pricing, licensing models, and interoperability standards, impacting the future of cloud computing.
Although AI’s direct impact on cloud competition is currently limited, the CMA anticipates its influence will expand significantly in the future, particularly given the intrinsic links between major cloud providers and cutting-edge AI model developers. The UK’s digital economy increasingly relies on this burgeoning cloud infrastructure market, which has witnessed nearly 30 percent year-on-year growth in customer expenditure.
The report concludes with a stern warning: with market power concentrated among a select few and rising apprehensions over interoperability and vendor lock-in, only decisive regulatory action can ensure a truly level playing field, fostering innovation and fair competition for all participants in the critical cloud sector.
