EU DMA Cloud Gatekeeper Proposal Targets Azure and AWS: What IT Admins Need to Know

EU cloud rules: what is confirmed and what is reported​

The reporting shifts a lot between "preliminary" and "final," so here is where things stand.

• November 18, 2025: The Commission opened three cloud market investigations. Two concern proposed gatekeeper designations for AWS and Azure. The third looks at whether existing DMA obligations can handle unfair or competition-limiting practices in cloud.
• June 25, 2026: The Commission told Amazon and Microsoft it had a preliminary view that they should be designated as gatekeepers for AWS and Azure. It preliminarily found that AWS and Azure, the largest and second-largest cloud services in the EU, are an important gateway between businesses and their customers.
• Thresholds: The finding came even though neither service meets the DMA's quantitative thresholds. Analysts say the case rests on qualitative criteria. The decisions would be the first to rely entirely on those qualitative criteria.
• Right to respond: Amazon and Microsoft can respond before any final decision. That makes this a proposed designation, not a finding that either company has broken the law.
• Early October 2026: Bloomberg reported that regulators are finishing the investigation. The Commission plans to name AWS and Azure as gatekeepers in November. The decision is still a draft, and its timing could slip, according to Bloomberg's sources. The Commission told Bloomberg its assessments were ongoing and no final decision had been made.

So the digest's "set to name" wording rests on anonymous sources. As of today, Azure is not a designated gatekeeper for cloud services.

What designation could mean for Microsoft shops​

Microsoft is already a designated gatekeeper under the DMA for other services. If the Commission confirms the cloud finding, cloud computing would be added to the list of core platform services for which Amazon and Microsoft are already designated.

The Commission's November 2025 description of its parallel inquiry names the likely pressure points:

• obstacles to interoperability between cloud services
• limited or conditioned access to data for business users
• tying and bundling of services
• potentially imbalanced contract terms

The ExchangeWire digest says classification would require interoperability and easier switching. The official material I reviewed lists those as subjects under investigation, not as obligations already imposed. Nothing I found sets a compliance deadline or a specific Azure setting that would change. One secondary analysis says a confirmed ruling could constrain egress fees, but that is that outlet's projection, not an official statement.

For admins, the practical points are modest for now:

1. Nothing changes in your tenant today. There is no new Azure setting or contract term tied to this.
2. Watch the renewal calendar. If you are negotiating EU Azure commitments, egress costs and portability terms are the likely areas to press on.
3. Document your dependencies. Knowing which workloads depend on Azure-specific services helps whatever the outcome.
4. Treat "gatekeeper" as a legal label, not a ruling on your vendor. Designation triggers conduct obligations. It does not mean Azure is unsafe or that migration is needed.

Counterpoints​

Critics argue the preliminary view stretches the idea of a gatekeeper. The International Center for Law & Economics says the Commission's position conflates gatekeeping with size. Supporters point to the Commission's statement that more than half of EU businesses rely on cloud services. They also point to its argument that AI tools and partnerships are now a deciding factor in cloud procurement. The ICLE brief and the analyses citing Synergy market-share figures are third-party views, not Commission findings.

The other two stories in the digest​

Apple and ad-tech blocking. AdExchanger reported on October 2 that, according to two sources with direct knowledge of WebKit updates, Apple scrapped an initial blocklist. It was replaced with a remotely updated library of hundreds of customer data platforms, ad-tech and martech firms, data sellers and identity-graph operators. The earlier list covered The Trade Desk, LiveRamp, ID5, Permutive and Audigent on iOS 27. Because browsers on Apple devices must use WebKit, other mobile browsers were also affected. AdExchanger could not publish or document the full list. It also had not confirmed whether Google properties are included. This is attributed reporting, not an Apple announcement, and it does not affect Windows.

Paramount and Warner Bros. Discovery. Axios reported that David Ellison announced the combined company will be named Skydance. Its ticker will be SKYD, according to an SEC filing, and Paramount and WBD expected to close on October 6. The digest cites a deal value of about $110 billion. A separate AP report I could not retrieve was said to give an $81 billion figure. I could not reconcile the two, so treat the value as unsettled.

Bottom line​

For Microsoft-focused readers, the one concrete fact is the Commission's June 25 preliminary position on Azure. A final November decision is reported but unconfirmed. Until it lands, cloud buyers should plan for possible changes to switching and interoperability terms, but not assume any have taken effect.
