EU Data Act Reshapes Cloud Switching: Google, Microsoft, AWS Adapt

Executive Signal Summary

The EU Data Act, which took effect on September 12, 2025, aims to make switching cloud providers easier by reducing artificial barriers to data portability. Google, Microsoft, and AWS have adjusted their data transfer pricing: Google waives egress fees for eligible multicloud workloads in the EU and UK, Microsoft has billed transfers at self-cost since August, and AWS offers reduced rates for specific use cases upon request. The article explains common misconceptions, such as free not applying to all charges, and highlights practical challenges for enterprises including data formats and APIs, identity and permission mapping, observability, compliance documentation, and migration windows. It recommends inventorying data flows, running realistic pilot tests, unifying interfaces, and practicing rollback scenarios. The author also mentions Gaia-X as a complementary European initiative for federated, trusted data sharing.

US Government Excludes Microsoft from Visa Program

The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
