Microsoft and Amazon are hurting cloud competition, UK regulator finds
Дата публикации: 31-07-2025 06:04:22
The U.K.’s Competition and Markets Authority said that Microsoft and Amazon both hold “significant unilateral market power” in the cloud services market. The regulator is concerned that certain cloud market practices are creating a “lock-in” effect where businesses are trapped into unfavorable contractual agreements. The CMA recommended a further investigation into Microsoft and Amazon under a strict new U.K. competition law to determine whether they have “strategic market status.”
LONDON — Britain’s competition regulator on Thursday said that Microsoft and Amazon are hurting competition in the cloud computing industry and called for a probe into their market dominance under the country’s strict new tech rules.
The Competition and Markets Authority said that market concentration and barriers to entry in the cloud services market have enabled both Microsoft and Amazon to hold “significant unilateral market power” and reap financial gain exceeding the cost of capital expenditure over a sustained period.
Tech giants like Amazon, Microsoft and Google have built huge businesses by offering access to computing resources — such as data storage and processing — via the internet using data centers, large facilities that contain dedicated hardware.
The CMA is concerned that certain practices within the space, such as egress fees and unfavorable licensing terms, are creating a “lock-in” effect where businesses are getting trapped into contractual agreements that are difficult to get out of.
Microsoft said the regulator’s decision “misses the mark again, ignoring that the cloud market has never been so dynamic and competitive, with record investment, and rapid, AI-driven changes.”
“Its recommendations fail to cover Google, one of the fastest-growing cloud market participants,” a Microsoft spokesperson told CNBC via email.
Amazon also disputed the CMA’s findings and said recommendations for a fresh probe into the two tech giants’ dominance of cloud were “unwarranted.”
“It risks making the UK a global outlier at a time when businesses need regulatory predictability for the UK to maintain international competitiveness,” an Amazon spokesperson told CNBC.
Google praised the CMA’s move, calling it a “watershed moment” for the U.K. Swift action will be “essential to ensure British businesses pay a fair price and to unleash choice, innovation and economic growth in teh U.K.,” Chris Lindsay, Google’s vice president of customer engineering for EMEA, said in a statement.
‘Strategic market status’
The watchdog took issue with technical and commercial restrictions in the cloud market that make it harder for firms to switch cloud provider and find better offers or more innovative new services from alternative providers.
It also took aim at licensing practices from Microsoft that make it cheaper to use the tech giant’s cloud-based Windows Server on its Azure cloud than competing services, saying the issue “further restricts the already limited choice and attractiveness of alternative products and suppliers.”
Microsoft and Amazon both hold a roughly 30% to 40% share of the so-called infrastructure-as-a-service (IaaS) market, which entails processing, storage, networking and other raw computing resources, the CMA said. Google is the third-biggest provider but holds a much smaller 5% to 10% IaaS market share, it said.
To address the issues, the CMA recommended a further investigation into Microsoft and Amazon under the Digital Markets, Competition and Consumers (DMCC) Act to determine whether they have “strategic market status.”
The DMCC is a recently introduced law in the U.K. that aims to prevent anti-competitive behavior in digital markets — akin to the Digital Markets Act in the European Union. Firms designated strategic market players are considered as having substantial and entrenched market power and can be subjected to targeted interventions to address competition concerns.
