Google has formally withdrawn its formal EU antitrust complaint against a rival’s cloud licensing practices — a tactical retreat that arrives just days after the European Commission opened three coordinated market investigations into the cloud sector under the Digital Markets Act (DMA).
Background
The complaint that Google has now withdrawn was originally filed last year and accused Microsoft of structuring licensing and pricing terms in ways that effectively tethered enterprise customers to Microsoft Azure. The allegation focused on commercial terms for widely used enterprise software and on pricing differentials that make it materially cheaper for customers to run Microsoft workloads on Azure than on rival clouds. That private enforcement route has now been superseded by a public, Commission‑led inquiry: on 18 November the European Commission announced three market investigations — one each targeted at Amazon Web Services and Microsoft Azure, plus a horizontal study to test whether the DMA’s toolbox is fit for cloud infrastructure markets. The Commission will use a qualitative market‑investigation pathway to determine whether AWS and Azure function as “important gateways” that should be designated as DMA gatekeepers, even if conventional numeric thresholds do not neatly apply.
What happened this week — the essentials
- Google withdrew its antitrust complaint shortly after the Commission announced the cloud probes; Google’s public statement framed the withdrawal as a practical response to Brussels’ decision to investigate cloud market practices publicly.
- The Commission’s actions comprise three coordinated inquiries: two company‑specific market investigations (AWS and Azure) and a horizontal sectoral review to assess whether the DMA’s existing obligations can effectively address cloud‑specific concerns such as interoperability, data portability and preferential treatment of first‑party services.
- Independent market trackers put the current global cloud infrastructure market concentration in stark terms: the “big three” hyperscalers — AWS, Microsoft Azure and Google Cloud — together account for more than 60% of worldwide infrastructure spending, with AWS at roughly 30%, Microsoft around 20% and Google at about 13%.
Overview: why the Commission moved on cloud now
The DMA was designed to curb entrenched platform power in consumer‑facing markets, but Brussels now argues the same structural mechanics — scale advantages, network effects, switching frictions and vertical integration — are visible in cloud infrastructure. The Commission’s public rationale touches three intertwined policy drivers:
- Market concentration and lock‑in: national regulators and independent analysts have documented how a small number of hyperscalers capture a dominant share of enterprise cloud spend, creating durable advantages in pricing, geographic footprint and breadth of managed services.
- Switching frictions and commercial mechanics: regulators cite contractual egress fees, proprietary control‑plane primitives, and licensing differentials that raise the cost and complexity of moving production workloads between clouds. These frictions are exactly the behaviors that drive complaints from rivals and customers.
- Systemic resilience and AI: high‑impact outages and the rapid growth of AI workloads have made cloud concentration not just a commercial concern but a resilience and strategic‑sovereignty issue for governments and businesses. Access to specialized accelerators and integrated AI stacks amplifies provider‑specific lock‑in.
The Commission has set a roughly 12‑month timetable for the company‑specific market investigations, with a somewhat longer horizon for the horizontal study that will assess whether the DMA needs tailored interpretation or delegated acts to cover cloud‑specific problems.
What the probes will actually look at
Investigators will seek concrete, auditable evidence: contract samples, pricing and rebate data, migration test results, architectural documentation, performance logs and stakeholder testimony. Key lines of inquiry include:
- Data portability and egress — are exit fees and tooling structured in ways that materially deter migration?
- Licensing and pricing differentials — do software licensing terms make it cheaper or operationally simpler to run Microsoft or other vendor workloads on their own cloud?
- Self‑preferencing and bundling — do first‑party managed services, marketplaces or consoles receive preferential placement, pricing or performance?
- Interoperability and proprietary control‑plane primitives — are APIs and orchestration primitives practically open or are they engineered to impede multi‑cloud portability?
Why Google withdrew: a tactical pivot, not a retreat
Google’s public explanation was straightforward: it withdrew the complaint “in light of the recent announcement that the EC will assess problematic practices affecting the cloud sector under a separate process.” That wording — published by Google Cloud Europe’s public‑policy lead — signals a shift from a bilateral enforcement strategy (file a complaint) to a multilateral regulatory one (work with Brussels as it conducts a market investigation). This move has several tactical advantages for Google:
- It elevates the dispute from a bilateral complaint, with limited discovery, to a broad, public market investigation with a defined timetable and the power to impose ex‑ante obligations.
- It reduces the immediate onus on Google to prove specific legal violations, replacing that burden with a public evidence‑gathering process that can compel documents and testimony from multiple market actors.
- It reframes the issue as a sectoral challenge — interoperability, portability and resilience — which aligns with broader regulatory priorities and increases political salience across EU member states.
Those benefits explain why a private complainant might step back at a moment when Brussels has chosen to wield the DMA’s investigatory powers.
Legal mechanics and possible outcomes
If the Commission concludes — after the qualitative market investigations — that AWS or Azure (or both)
functionally act as DMA gatekeepers, the consequences are material and swift. Designation would add the cloud services to the list of core platform services subject to a prescriptive set of
obligations and prohibitions, including:
- Non‑discrimination toward third‑party business users;
- Interoperability and technical access duties where feasible;
- Data‑portability requirements and limits on tying or bundling;
- Restrictions on practices deemed to be self‑preferencing.
Designated gatekeepers face heavy enforcement tools under the DMA: fines can reach up to
10% of global annual turnover for a first breach and larger penalties for repeat offenses, plus behavioural or structural remedies where justified. The Commission’s market investigations can lead to designation via a qualitative pathway even if the usual numeric thresholds (EU turnover and user metrics) are absent — a crucial legal pivot that makes cloud an immediate DMA target.
Market context and the numbers that matter
Independent market trackers and industry analysts back up the Commission’s concerns about concentration. Synergy Research Group’s most recent trackers and aggregated charts put the global infrastructure market shares at roughly:
- AWS ~30%
- Microsoft Azure ~20%
- Google Cloud ~13%
Those figures are consistent across other industry datasets and confirm that the top three hyperscalers together account for well over 60% of global IaaS/PaaS spending. That concentration — especially when combined with differential pricing and specialized AI hardware access — helps explain why regulators view cloud as a potential gatekeeper domain. Caveat on precision: market‑share estimates vary by methodology (IaaS vs full cloud stack, geographic segmentation, quarter vs trailing‑twelve‑month windows). Nonetheless, the overall picture — a high level of concentration among the large hyperscalers — is robust across multiple data sources and national regulator briefs.
Practical implications for vendors and enterprise customers
The Commission’s probes — and Google’s withdrawal of its private complaint — change the regulatory calculus for every major cloud actor and for their customers. The immediate implications include:
- For Microsoft and AWS: expect deep document requests, detailed technical audits and a regulatory push to justify current licensing, marketplace practices and any preferential arrangements with ecosystem partners. If designated, they will face prescriptive obligations that could force product and commercial redesigns.
- For Google: the withdrawal is a pragmatic bet that a public, cross‑sector regulatory process is a more effective route to the remedies Google seeks. But it also reduces Google’s control over the pace and framing of the evidence that regulators will collect.
- For enterprise customers and public procurers: the probes increase the likelihood that contracts will be scrutinized and that regulators may require clearer, enforceable migration guarantees and interoperability terms. Procurement teams should treat the Commission’s action as a prompt to harden exit clauses and migration testing.
Short checklist for procurement and legal teams
- Audit current cloud contracts for egress fees, portability commitments and vendor‑specific licensing differentials.
- Add or strengthen migration acceptance testing and technical export guarantees in SLAs.
- Insist on independent performance audits and audit‑friendly contractual clauses.
- Evaluate multi‑cloud portability at the architecture level — not just at contract terms.
- Document the business case for vendor choice and any switching‑cost estimates, which will help if regulatory or procurement disputes arise.
Risks and unintended consequences
There is a strong public interest case for greater contestability and portability in cloud markets, but regulatory intervention also carries genuine risks and trade‑offs:
- Complexity of translating DMA obligations to cloud: the DMA’s metrics and remedies were designed for consumer platforms; mapping them coherently onto infrastructure‑level services raises thorny technical questions (control‑plane APIs, multi‑petabyte data portability, latency‑sensitive workloads). The Commission’s horizontal probe explicitly aims to test this mapping.
- Investment disincentives: heavy‑handed ex‑ante obligations or structural remedies could deter the capital‑intensive investments required for new data centers, specialized accelerators, and regional resiliency — the very infrastructure Europe wants to expand for AI sovereignty. Companies have warned regulators against remedies that might raise costs or slow innovation; those trade‑offs are likely to surface during stakeholder hearings.
- Regulatory overreach and fragmentation risk: inconsistent remedies across jurisdictions (UK CMA, EU Commission, national authorities) could fragment the market and complicate cross‑border enterprise operations, adding compliance costs.
Regulators will need to balance the benefits of stronger ex‑ante rules against the complexity of cloud technical realities and the risk of chilling future infrastructure investment.
What to expect next — timeline and cadence
The Commission has signaled an accelerated evidence‑gathering phase with the following rough milestones:
- Company‑specific market investigations (AWS and Azure): evidence gathering and analysis over approximately 12 months, after which the Commission may issue a formal designation decision under the DMA’s qualitative pathway.
- If designated: companies typically have a narrow window (commonly six months) to implement DMA obligations. Non‑compliance risks fines and additional enforcement measures.
- Horizontal DMA fitness study: this sectoral review could result in a final report and potential delegated acts to adapt DMA obligations to cloud‑specific needs; the horizontal probe’s timeline may extend beyond the company inquiries, reflecting detailed technical consultation.
Expect intensive stakeholder engagement, confidential document exchange and public hearings. Enterprises and vendors should prepare for a sustained regulatory dialogue rather than a quick resolution.
Strategic takeaways — who wins, who loses, and what to watch
- Regulatory leverage is rising: Google’s withdrawal accelerates a shift from private enforcement to systemic regulation. If Brussels secures robust remedies, the competitive landscape for cloud could change materially — opening opportunities for smaller providers and specialized AI infrastructure players.
- Microsoft and Amazon sit at the center of regulatory risk: both will have to defend not only their commercial terms but also deep technical design choices. The stakes include not just fines, but changes to product design and partner economics.
- Enterprises gain negotiating leverage: regulators scrutinizing contract terms gives customers an opening to demand stronger migration guarantees, audit rights and non‑discriminatory access commitments. Procurement teams should act quickly to capture those gains in renewed contracts.
Key signals to monitor over the next 12 months:
- Whether Brussels designates AWS and/or Azure as DMA gatekeepers and, if so, the specific obligations attached.
- Any public commitments or technical roadmaps published by the hyperscalers in response to evidence requests.
- The horizontal probe’s recommendations about adapting DMA obligations to cloud‑level realities — a potential blueprint for EU cloud governance.
Critical analysis: strengths and shortcomings of the current path
Strengths
- The Commission’s approach is comprehensive. By combining company‑level investigations with a horizontal study, Brussels avoids narrow remedies and seeks systemic fixes that could improve portability, non‑discrimination and resilience across the cloud stack. That mixed approach helps policymakers account for both legal and technical complexity.
- A public, evidence‑based DMA probe can compel cross‑industry disclosure that private complaints cannot, increasing the factual basis for durable remedies. For rivals and customers who have struggled to surface contract terms and pricing practices, this is a major enforcement win.
Shortcomings and risks
- Translating consumer‑facing DMA obligations into meaningful cloud requirements is non‑trivial. There is a real risk that prescriptive remedies will be analytically or technically unworkable, or that they will produce perverse incentives that harm investment in European infrastructure.
- The investigative timeline and legal complexity will keep uncertainty elevated for customers and vendors, potentially slowing procurement decisions and multi‑year cloud investments precisely when AI demand is accelerating. Regulatory clarity is needed, but not at the cost of precipitate remedies.
How to prepare — a tactical playbook for IT and procurement leaders
- Start a contract audit program. Identify clauses that create switching friction: egress fees, licensing differentials and exclusive bundle terms.
- Commission migration proof‑of‑concepts for critical workloads: test export formats, data transfer performance, and orchestration portability.
- Strengthen RFP language: require immutable and testable export deadlines, independent performance metrics and rights to third‑party audits.
- Map AI pipelines and specialized accelerator dependencies: where GPU or TPU access is a single‑vendor dependency, build contingency plans and replication paths.
- Engage legal and policy teams early: stay ready to provide evidence or testimony if your organization is approached by regulators.
Conclusion
Google’s withdrawal of its EU complaint is less an admission of defeat than a strategic re‑alignment: when Brussels steps in with sector‑wide investigations under the Digital Markets Act, private grievances gain amplification and the potential for broad, enforceable remedies. The Commission’s decision to test the DMA’s suitability for cloud markets is a watershed moment for European cloud governance — one that could reshape commercial terms, technical design choices and the economics of global cloud infrastructure.
That outcome could widen choice for customers and restrain exclusionary practices, but it also confronts regulators with thorny technical questions and trade‑offs between competition and investment. Over the next 12 months, enterprises, vendors and policymakers will need to navigate an unusually tight interplay of law, engineering and procurement. The winners will be those who prepare early — legal, procurement and architecture teams that translate regulatory risk into concrete contract protections, verified migration tests and resilient multi‑cloud strategies.
