Docs: in an informal Azure investigation, EU regulators ask rivals and clients if Microsoft leveraged its market power and business info to squeeze competitors
Context & Ripple Effects
This informal outreach is an early signal that EU scrutiny of Microsoft was extending beyond individual products to how Azure’s position might shape competition. It foreshadows a later inquiry into alleged restrictions around customers’ use of rival identity-management software.
The issue also fits a broader cloud-competition record: Google later alleged unfair cloud practices tied to customers’ dependence on Microsoft products, while the Commission subsequently examined whether AWS and Azure’s strong positions warranted DMA designation.
First-order effects
- Azure rivals and customers become evidence sources for regulators, with their account and procurement information central to testing the alleged conduct.
- Microsoft faces an informal competition review of whether it used market power and business information to disadvantage competitors; the outreach itself does not establish a violation.
Second-order effects
- Competitors gain a formal channel to document interoperability, contracting, or information-use concerns, increasing pressure on Microsoft to defend its cloud practices.
- The inquiry broadens the competitive focus from cloud infrastructure alone to the surrounding enterprise software stack, a theme echoed by the later Entra ID-related probe.
Third-order effects
- If such inquiries produce enforceable findings, cloud competition policy could increasingly assess how infrastructure, operating systems, identity, and business data reinforce one another rather than treating them as separate markets.
- The case points toward more regulator attention to dependency in enterprise cloud ecosystems, alongside later scrutiny of Azure and AWS under the DMA framework; whether that yields new obligations depends on the outcomes of those reviews.
The trend: European competition scrutiny is increasingly examining whether hyperscalers can use control of enterprise ecosystems to extend cloud-market power into adjacent software layers.
