Executive Summary
Amazon Web Services (AWS) continues to try to increase its UK market share, but Microsoft Azure is rapidly gaining ground. A report by the Competition and Markets Authority (CMA) highlights that AWS, despite its leading position, is experiencing a slight decline in market share.
In contrast, Microsoft Azure shows significant growth in both revenue and new user acquisition, accompanied by higher profit margins. The CMA is also investigating potential competitive barriers, such as Microsoft's software licensing practices and data egress fees.
