Google’s abrupt withdrawal of its EU antitrust complaint against Microsoft’s cloud licensing is the latest twist in a transatlantic tussle over the future of cloud competition — and it comes as the European Commission has opened formal market investigations to determine whether Microsoft Azure and Amazon Web Services should be treated as “gatekeepers” under the EU’s Digital Markets Act (DMA). The move shifts the dispute from a bilateral enforcement complaint to a broader regulatory probe that could impose sweeping conduct obligations on two of the industry’s biggest hyperscalers, with implications for enterprise customers, European cloud players, and the shape of cloud competition for years to come.
The Commission’s market investigations create a genuine moment of potential change in cloud market rules. They promise clearer answers on interoperability, portability, and fairness — but they also risk creating administrative burdens and technical challenges that will need careful calibration. Ultimately, the path to more open, competitive cloud markets will require well-targeted remedies, harmonised technical standards, and continued pressure from customers who vote with contracts and migrations, not just public statements.

Background
What Google filed — and what it alleged
Google Cloud had publicly complained about Microsoft’s cloud licensing for more than a year, arguing that certain licensing conditions and contractual terms effectively lock customers into Microsoft Azure and discourage migration to competing clouds. The complaint amplified concerns about vendor lock-in, bundled licensing, and contractual terms that may impose financial penalties or operational friction on customers who choose multicloud deployments. Google reiterated these claims in its public blog post discussing the complaint and later appended an editor’s note to confirm its withdrawal in light of the Commission’s new investigation. Some reporting framed Google’s initial action as a formal antitrust complaint lodged with the European Commission in 2024, while other accounts have traced the origins of the grievances to earlier interactions among industry players and trade bodies. The public record is clearest around the company’s September 2024 blog and the formal complaint it lodged thereafter; where multiple dates appear in coverage, caution is warranted because reporting and corporate disclosures have referenced both 2024 and earlier exchanges.Why the Commission stepped in
In mid-November 2025 the European Commission announced three market investigations under the DMA aimed at the cloud sector. Two of those probes will specifically assess whether Amazon Web Services (AWS) and Microsoft Azure act as “important gateways” between businesses and consumers — in other words, whether they should be treated as gatekeepers even if they do not meet the DMA’s quantitative thresholds in a mechanical way. A third investigation will analyze whether the DMA’s rules are fit for the cloud market generally, including whether they are capable of addressing issues such as interoperability obstacles, conditioned access to data, and tying or bundling practices. The Commission set a one-year horizon for the investigations.What the probe covers — and what it could change
The Digital Markets Act: a short primer
The Digital Markets Act (DMA) is the EU’s regulatory framework designed to curb unfair platform practices and ensure contestability in so-called “core platform services.” If a service is designated as a gatekeeper, it becomes subject to a prescribed set of prohibitions and obligations — for example, restrictions on self-preferencing, requirements to enable interoperability or data portability, and obligations to allow fair access for third parties. The DMA aims to prevent market-dominant platforms from entrenching their positions and to open markets to rivals and customers. The Commission’s cloud-focused investigations are meant to test how these rules translate to a sector where infrastructure, software, and enterprise contracts interlock.Which behaviors are under scrutiny
The Commission explicitly listed areas of concern that include:- Interoperability barriers between cloud providers and enterprise software, which can raise switching costs.
- Conditioned access to data for business users, including limits on portability and export.
- Tying and bundling of cloud infrastructure with software or services that favor the incumbent provider.
- Imbalanced contractual terms that may impose asymmetric risks or fees on customers who choose competing clouds.
The competitive landscape today
Hyperscaler market structure in 2025
The cloud infrastructure market is heavily concentrated among the top three providers: AWS, Microsoft Azure, and Google Cloud. Independent market trackers reported that these three account for roughly 60–65% of global cloud infrastructure spending in 2025, with AWS leading and Microsoft and Google holding sizeable second- and third-place shares. Public estimates in late 2025 put AWS in the high-20s to low-30s percent range, Microsoft around 20%, and Google roughly 10–13%, depending on the dataset. That level of concentration is precisely what has focused regulatory attention — especially since cloud becomes the backbone for AI, government services, and critical enterprise functions.What drives lock-in in cloud
Customer lock-in in cloud environments is rarely a single factor. Instead, it is the result of multiple interlocking dynamics:- Long-term licensing terms and enterprise agreements that tie productivity software or platform services to a specific cloud.
- Platform-specific integrations, APIs, and performance optimizations that make migration costly to re-engineer.
- Data gravity: once a company’s data and workloads live in a provider’s ecosystem, moving them generates direct migration costs and indirect business disruption.
- Specialized cloud services (e.g., proprietary AI accelerators, managed AI platforms) that are not portable across providers.
Why Google withdrew the complaint — strategic and regulatory reasoning
From complaint to coordinate-with-regulator strategy
Google’s stated reason for withdrawing was pragmatic: the Commission’s decision to launch targeted market investigations under the DMA means the regulator will now assess the very concerns Google raised — not on a case-by-case antitrust complaint basis but through a structured DMA process. Google framed the withdrawal as a nod to regulatory efficiency and signalled it would continue to lobby for openness and customer choice in the EU and UK. The withdrawal also leaves the complaint’s substantive claims available to be considered in a broader, systemic inquiry rather than a narrow bilateral enforcement action.Litigation fatigue and the settlement background
There is a second, practical reason. Some of the cloud licensing concerns previously raised by smaller European cloud providers were settled with Microsoft through industry negotiations; Microsoft has publicly said it reached agreements to address many of these issues. That reduced the need for multiple concurrent complaints and left Google as a solitary complainant on some points — a weaker position politically and legally. Shifting the debate to the Commission’s broader DMA probe creates a higher-profile venue where systemic remedies can be considered and where Google’s arguments can be paired with industry evidence.Microsoft’s position and posture
Public commitments and a defensive strategy
Microsoft has positioned itself as law-abiding and cooperative with European regulators. The company has publicly emphasised investments in European datacenters, commitments to data sovereignty and EU-specific compliance measures, and a willingness to adapt product terms to satisfy policy objectives. Microsoft’s public statements have pointed to settlements and commitments it claims address several third-party concerns, arguing that its licensing model supports flexibility while preserving security and compatibility across enterprise customers.The practical business risk
If the Commission designates Azure as a gatekeeper — or otherwise enforces behavioral remedies specifically tailored to cloud — Microsoft would face significant compliance obligations. These could include measures to ensure non-discriminatory access, limitations on tying platform services with cloud infrastructure, and enhanced data portability or interoperability duties. Compliance would require both contractual changes and potentially technical rework on how services are integrated across Azure’s stack.What’s at stake for customers, competitors, and regulators
For enterprise customers
At the simplest level, customers want three things: choice, predictable pricing, and operational control. The Commission’s probe could deliver outcomes that reduce contractual friction and lower switching costs, if regulators force greater interoperability or clearer contractual terms. But regulatory action can take time and, depending on the remedy design, might also introduce short-term complexity as vendors update terms and systems. In other words, the prospect of more choice may coexist with transitional friction.For smaller cloud providers and European players
European cloud providers and regional players have lobbied for regulatory action precisely because of the scale advantage enjoyed by hyperscalers. A favorable DMA outcome could level the playing field by removing design choices that favor incumbents. But realistically, structural advantages — scale, breadth of services, and capital to invest in proprietary AI infrastructure — aren’t easily undone by regulatory decrees. The remedies could help competition at the margins (interoperability, contract fairness), but not necessarily reverse scale economics.For Microsoft and AWS
Designation under the DMA would be a material change. For Microsoft especially, which has integrated its productivity stack, developer tooling, and cloud infrastructure, obligations to prevent self-preferencing and to enable competitor access could affect commercial strategy and product roadmaps. AWS would face similar scrutiny given its scale and central place in enterprise infrastructure. The Commission’s process, though, is designed to be careful: a gatekeeper designation is not an automatic finding; it requires a factual record and legal analysis.Legal and practical pitfalls in proving harm
Antitrust and regulatory interventions must clear high evidentiary bars. Demonstrating that specific licensing terms cause anticompetitive foreclosure — rather than merely reflecting product integration or legitimate bundling — requires careful economic and factual analysis. Regulators will weigh:- Whether contractual practices are objectively necessary for security, interoperability, or compliance.
- The quantifiable costs of switching and whether those costs are reasonably attributable to provider behavior or to generic migration friction.
- Evidence of exclusionary intent or effects, rather than mere competitive advantage.
Potential regulatory outcomes and business consequences
- Gatekeeper designation for AWS and/or Azure, triggering DMA obligations and enforcement mechanisms.
- Behavioral remedies limited to specific practices (e.g., contractual terms, interoperability standards) without full gatekeeper designation.
- No designation but industry-wide guidance or voluntary commitments to address particular issues.
- Protracted litigation and appeals, if the companies contest the designation or specific remedies in EU courts.
Practical advice for IT decision-makers
Enterprises should act now to reduce exposure to supplier-specific friction and to position themselves for either a smoother transition or more favorable contract terms:- Conduct a vendor lock-in audit to identify services and datasets tied to any single provider.
- Negotiate explicit contractual portability and exit clauses that address migration timing, technical artifacts, and cost caps.
- Architect applications with portability in mind: favor open standards, containerization, and platform-agnostic data formats.
- Use encryption and key-management approaches that ensure control over data access independent of the cloud provider.
- Budget for multicloud testing and proof-of-concept migrations so switching isn’t a once-in-a-decade gamble.
- Document compliance and security requirements that must travel with workloads to reduce rework when migrating.
Risks and unintended consequences of regulatory intervention
- Overbroad remedies could force complex technical changes at scale, increasing costs for providers and potentially passing them on to customers.
- Fragmentation risk: mandates that require interoperability at the protocol level could yield multiple compliance approaches and an interoperability zoo unless harmonized standards are adopted.
- Innovation chilling: if providers are restricted from bundling or from building proprietary optimizations, some product innovations may slow or become less economically viable.
- Regulatory gaming: vendors may shift commercial practices or geographic packaging in ways that comply with letter-of-the-law but undermine the DMA’s policy goals.
What to watch next — timeline and milestones
- The European Commission’s investigations are expected to run on a roughly one-year timetable from their November 18, 2025 start, with follow-on actions possible thereafter. That means stakeholders should expect incremental findings, rounds of information requests, and the possibility of interim measures or commitments.
- Public consultations and technical fact-finding: the Commission will solicit evidence from market participants, which is an opportunity for enterprises and regional providers to influence the record.
- Potential remedial proposals: if the Commission identifies specific problematic practices, it could seek commitments from Microsoft or AWS or propose DMA-based obligations tailored to cloud services.
- Secondary proceedings: national competition authorities and sectoral regulators (e.g., data protection or telecom authorities) may open parallel inquiries or adopt complementary measures.
Concluding assessment
Google’s decision to withdraw its complaint against Microsoft is strategic rather than conciliatory: it hands the issue to the European Commission’s DMA machinery, where system-level remedies and sector-wide analysis can be pursued. That shift raises the stakes for both Microsoft and AWS because a DMA-based finding of gatekeeper status would bring formal, ex ante obligations that are more prescriptive than classical antitrust remedies. For enterprise IT leaders, the immediate lesson is practical: take control of migration risk and strengthen contractual protections while watching the regulatory process — because the outcome could reshape vendor conduct and contractual norms across the cloud market.The Commission’s market investigations create a genuine moment of potential change in cloud market rules. They promise clearer answers on interoperability, portability, and fairness — but they also risk creating administrative burdens and technical challenges that will need careful calibration. Ultimately, the path to more open, competitive cloud markets will require well-targeted remedies, harmonised technical standards, and continued pressure from customers who vote with contracts and migrations, not just public statements.
