An antitrust investigation has been opened into cloud computing in the UK after concerns were raised about the dominance of the US hyperscale providers, particularly Amazon's AWS and Microsoft Azure. The Competition and Markets Authority (CMA) has launched the probe on the recommendation of communications regulator Ofcom, after it concluded a year long study of the market.

Today's report follows an interim statement from Ofcom released in April, where it raised worries about the state of the market and the position of AWS and Azure within that. Its final statement says that it has uncovered "features that could limit competition" and says it is often difficult and expensive for businesses to switch providers.
