Microsoft and Amazon Web Services reportedly face strict antitrust regulation from the European Union According to a report by Golden Finance, on June 19th, Microsoft's Azure and Amazon Web Services (AWS) will face strict antitrust regulation following a preliminary investigation by the European Union into monopolistic forces in the cloud computing market. According to reports, the European Commission is expected to release preliminary investigation results as early as next week, indicating that AWS and Azure may meet the regulatory requirements of the EU's Digital Markets Act (DMA). Insiders say that the EU is expected to make a final decision by the end of this year, but the timeline may still change. If the services of these tech giants are ultimately fully regulated by DMA, they will face a series of obligations, including interoperability requirements and restrictive measures against customer lock-in and self preferential behavior.
