EU Considers Cracking Down on Big Tech's Cloud Power

Amazon Web Services, Microsoft Corp.’s Azure, and Alphabet Inc.’s Google Cloud risk being dragged into the scope of the European Union’s crackdown on Big Tech as antitrust watchdogs prepare to study the platforms’ market power.

The European Commission wants to decide if any of the trio should face a raft of new restrictions under the bloc’s Digital Markets Act, according to people familiar with the matter who spoke on condition of anonymity. The plan for a market probe follows several major outages in the cloud industry that wrought havoc across global services, highlighting the risks of relying on a mere handful of players.
