Amazon and Microsoft have a combined market share in the range of 60% to 70% of the cloud computing market while Google (GOOGL) has a market share between 5% and 10%.
Ofcom pointed out that besides high switching costs, technical restrictions and discounts that encouraged customers to stick to a single provider even if better quality alternatives were available could all be considered anti-competitive.
The regulator stated, “High levels of profitability for AWS, and substantial consistent growth in Microsoft’s profits, indicate there are limits to overall competition. We are concerned that constraints on customers’ ability to use more than one provider could make it harder for smaller cloud providers to win business and compete with the market leaders.”
