UK Antitrust Watchdog Raises Concerns Over Cloud Market Dominance by Amazon and Microsoft The UK’s Competition and Markets Authority (CMA) has raised significant concerns about competition in the cloud computing market, naming Amazon Web Services (AWS) and Microsoft Azure as the dominant players. In a provisional report released Tuesday, the CMA highlighted the limited choices businesses face in the £9 billion ($11.18 billion) cloud services market, which is growing at over 30% annually. Key Findings from the CMA Report Market Dominance: AWS and Microsoft collectively account for up to 80% of UK customer spend on cloud services, with Google trailing far behind as the third-largest provider. Barriers to Competition: The CMA identified several practices that could stifle competition, including: [object Object], [object Object], [object Object] The CMA’s inquiry group has provisionally recommended investigating AWS and Microsoft under new digital markets legislation. This move aims to address the lack of competition and ensure a level playing field for smaller cloud providers. The probe stems from a 2022 study by UK telecoms regulator Ofcom , which initially flagged concerns about the dominance of Amazon, Microsoft, and Google in the cloud market. Ofcom later referred the matter to the CMA for further action. Cloud computing is a critical backbone of modern businesses, enabling everything from data storage to AI development. However, the dominance of AWS and Microsoft has raised fears of monopolistic practices, which could lead to higher costs, reduced innovation, and fewer choices for businesses. The UK’s concerns echo similar regulatory actions worldwide. In the EU, AWS is reportedly in talks with Italy to invest billions of euros in expanding its data center business, further solidifying its presence in Europe. Meanwhile, Microsoft continues to expand Azure’s global footprint, leveraging its strong enterprise relationships. The CMA’s final report is expected later this year, and its recommendations could lead to stricter regulations or even fines for AWS and Microsoft. For businesses, this could mean more competitive pricing, better interoperability, and greater flexibility in choosing cloud providers.
