Reshaping Enterprise Cloud Strategy in a Highly Regulated European Environment
The long-term consequence of the DMA’s and Data Act’s success in this sector will be a fundamental alteration of enterprise cloud strategy. The regulatory oversight promises a market where switching costs are demonstrably lower, and where leveraging multi-cloud environments becomes a genuine strategic option, rather than a complex, heavily penalized exercise in vendor negotiation.
For any organization with a significant European footprint, the playbook needs updating for 2026 and beyond. Inertia, which has long favored incumbents like Azure and AWS due to massive sunk costs and complex licensing, is now facing unprecedented regulatory headwinds.
Do’s and Don’ts: Navigating the Near-Term Compliance Landscape (The Six-Month Horizon)
While we wait for the Commission’s definitive gatekeeper designations—expected in late 2026—the *risk* of designation remains a critical planning factor. Companies must audit their current commitments based on the potential DMA obligations that Microsoft and Amazon will face:. Find out more about EU DMA impact on Microsoft Azure compliance.
The DMA ‘Do’s’ for Incumbents (and Opportunities for Enterprises):
- Data Portability Mandates: Ensure you have a clean path to extract all data, metadata, and configurations in a non-proprietary format.
- Anti-Self-Preferencing: Scrutinize your contracts to ensure no language implies you are being forced to use a vendor’s specific database or analytics tool over a competitor’s just because you use their compute engine.
- Interoperability Requirements: Expect greater standardization around core services like identity management and virtual networking to simplify cross-platform deployment.. Find out more about UK CMA scrutiny of cloud market power guide.
The Strategic ‘Don’ts’ for Enterprises Today:
- Don’t Commit to Long-Term, Non-Cancellable Contracts: Until the DMA compliance framework is fully established, lock-ins extending past 2027 should be scrutinized heavily, especially given the Data Act’s zero-fee deadline.
- Don’t Ignore UK Developments: The CMA’s SMS recommendation means UK-based operations might face unique, bespoke requirements even before the EU fully enforces its rules. Keep an eye on the CMA Board’s next steps in early 2026.
- Don’t Stop Advocating: Continue to work with trade bodies like CISPE to provide regulators with the real-world friction points that will shape the final rules on licensing fairness.

The old model was: Pick the best provider, integrate deeply, and accept the switching cost as the price of admission. The new model must be: Pick the best *tool* for the job, ensure it runs equally well on two different hyperscalers, and negotiate with a baseline of architectural freedom.
Here are actionable tips for your enterprise cloud strategy right now:
- Conduct a “Portability Audit”: For your top three critical workloads on AWS and Azure, map out the exact steps, time, and cost required to migrate them to a third-party IaaS or a rival cloud. This exercise, informed by the spirit of the Data Act, will reveal your true lock-in level.
- Prioritize Data Act Compliance in New Contracts: Ensure any new B2B data processing contract explicitly references the Data Act’s switching obligations, even if the contract technically falls under the transitional clause until 2027. Clarity today prevents surprises tomorrow.. Find out more about Reducing customer lock-in cloud strategy strategies.
- Budget for Abstraction Layers: Invest engineering resources now in building abstraction layers (e.g., using open-source database systems or container orchestration like Kubernetes) that sit above the vendor-specific APIs. This is the technical armor against future compliance mandates.
This is an expensive, complicated process—it is the cost of sovereignty in the digital age. But the alternative, relying on the goodwill of a designated gatekeeper, is quickly becoming a legally untenable position in the European theater.
Conclusion: The Age of Mandated Openness is Here
As of this final day in November 2025, the message from regulators across the Atlantic is deafeningly clear: the era of the self-contained, proprietary cloud ecosystem is drawing to a close. The EU’s DMA investigations into Azure and AWS, targeting a 12-month conclusion, combined with the immediate impact of the Data Act (applicable since September 2025), are forcing a proactive reckoning for the world’s largest cloud providers. Simultaneously, the UK’s CMA has already confirmed the “significant unilateral market power” of these same providers, setting the stage for UK-specific interventions..

Key Takeaways for the Industry Today:
- Timelines are Real: Six months post-designation (by mid-2026 at the latest, based on the 12-month probe target) is the hard deadline for DMA compliance for any designated cloud service.
- Switching Costs are Decaying: The Data Act has already begun dismantling financial barriers, with total elimination of exit fees mandated by January 2027.
- Interoperability is King: Regulations are moving beyond punishing past behavior toward mandating the architectural openness that enables genuine multi-cloud strategy.
The regulatory pressure cooker is officially on high. Your enterprise strategy—whether for procurement, architecture, or vendor management—must reflect this new reality. The next 18 months will not be about waiting for antitrust rulings; they will be about implementing necessary, structural compliance changes dictated by the DMA and the Data Act..
