When a company talks about cloud sovereignty, the conversation almost always ends up in the same place: where are the servers located? If the answer is “Europe,” many organizations consider the issue resolved.
But the reality is much more complex.
Physical infrastructure is only one part of the equation. It also matters who owns that infrastructure, who operates the network, under what legislation the provider works, who manages the systems, and what certifications truly back those operations.
Digital sovereignty doesn’t start when a virtual machine boots up. It begins much earlier—at the moment when the entire technological chain supporting the service is designed and controlled.
The keys to cloud sovereignty in 20 seconds
- The location of the data center is important but not enough to speak of digital sovereignty.
- Ownership of the infrastructure, the applicable jurisdiction, and who operates the systems also matter.
- Stackscale is part of Grupo Aire, a European telecom and digital infrastructure operator with its own network and services.
- Grupo Aire holds certifications such as ENS High, ISO 27001, ISO 27017, ISO 27018, ISO 22301, ISO 9001, and ISO 14001, among others.
- Choosing a cloud provider also means choosing a control model over the data and infrastructure.
For years, the market focused on computing capacity, available services, or the hourly cost of a virtual machine. However, the acceleration of artificial intelligence, increasing European regulations, and geopolitical tensions have shifted the debate toward a deeper issue: who truly controls the infrastructure on which a company’s critical data runs.
Server location is no longer enough
A company can run its workloads in Madrid, Paris, or Frankfurt and still depend on technological or legal decisions made outside Europe.
Physical location remains important for latency, regulatory compliance, and data residency, but it alone cannot answer fundamental questions such as:
- Who manages the platform?
- What legislation affects the provider?
- Who controls the network over which data circulates?
- Where are backups stored?
- What happens if an organization decides to change providers?
These issues are part of the concept of cloud sovereignty and are becoming increasingly significant in sectors such as government, industry, healthcare, defense, and financial services.
It’s not just about complying with regulations. It’s also about reducing technological dependencies and maintaining decision-making capacity over infrastructures deemed strategic.
Infrastructure is also part of sovereignty
Often, cloud is perceived as an abstract service where resources are deployed from a web console.
Behind this simplicity lies a physical infrastructure composed of data centers, fiber networks, storage, electrical systems, cooling, virtualization platforms, and operational teams working around the clock.
The greater the control a provider has over this infrastructure, the less dependent it is on third parties to deliver the service.
This is one of the factors that sets major specialized operators apart from models where critical components depend on different companies.
Stackscale and Grupo Aire: European infrastructure under one group
In Spain, there’s an example of this integrated model.
Stackscale is part of Grupo Aire, a European telecom and digital infrastructure operator providing services to companies, public administrations, and carriers.
Being part of the group allows combining cloud infrastructure with a proprietary communications network, enterprise connectivity, data center interconnection, and managed services—all within a single technological ecosystem.
Stackscale offers the cloud infrastructure layer through solutions such as dedicated servers, private cloud, storage, virtualization platforms, GPUs for AI, and architectures designed for critical business workloads.
This integration reduces reliance on multiple providers to build hybrid infrastructures and ensures that connectivity and computing evolve in a coordinated manner.
Certifications are also part of the infrastructure
Talking about sovereignty isn’t just about where servers are located.
It also involves demonstrating that the infrastructure is managed according to internationally recognized standards.
In this regard, certifications from Grupo Aire are particularly important, including:
| Certification | What it provides |
|---|---|
| ENS High | Ensures compliance with the requirements set by Spanish public administrations for high-criticality systems. |
| ISO 27001 | Information security management system. |
| ISO 27017 | Specific security controls for cloud services. |
| ISO 27018 | Protection of personal data in cloud environments. |
| ISO 22301 | Business continuity management. |
| ISO 9001 | Quality management. |
| ISO 14001 | Environmental management. |
While these certifications do not replace a solid technical architecture, they provide objective evidence of the processes managing the infrastructure.
The especially relevant combination of ENS High, ISO 27017, and ISO 27018 combines specific cloud service requirements with controls aimed at protecting information and personal data.
Artificial intelligence once again highlights infrastructure
The advent of generative AI has shown that the real bottleneck isn’t just the software.
Models can run on any compatible platform, but the availability of GPUs, electrical capacity, low-latency connectivity, high-performance storage, and proximity between these elements directly depend on the infrastructure.
For this reason, major global providers are investing billions of euros in new data centers and high-capacity networks.
Europe faces the same challenge from a different angle: strengthening its technological capacity without relying solely on external infrastructures.
In this context, having European operators with proprietary infrastructure becomes a relevance that a few years ago would have seemed secondary.
The right question is no longer where the data is
Many organizations still start their selection process by asking where the servers are physically located.
It’s a necessary question.
But it’s no longer enough.
The decision should be broadened to include other equally important issues:
- Who controls the infrastructure?
- Who operates the network?
- What certifications back the service?
- What legislation is applicable?
- How could the entire infrastructure be migrated if necessary?
Answering these questions allows for a much broader evaluation of cloud sovereignty than just geographic location.
Because digital sovereignty doesn’t start when a virtual machine is created.
It begins much earlier—in the capacity to control the infrastructure that makes that machine possible.
Frequently Asked Questions
Does cloud sovereignty depend only on the country where the data center is located?
No. Ownership of the provider, applicable legislation, infrastructure management, connectivity, and certifications that back the service also influence sovereignty.
What benefits does Stackscale’s belonging to Grupo Aire provide?
It allows integrating cloud services over infrastructure supported by a European operator with its own network, experience in telecommunications, and a wide range of security and continuity certifications.
Why are certifications like ISO 27017 or ENS Alto important?
Because they certify that the infrastructure and processes meet specific requirements for cloud services and for organizations handling sensitive information or providing services to the public sector.
Does cloud sovereignty eliminate all risks?
No. Measures such as encryption, backups, network segmentation, identity management, and proper security architecture remain necessary. Sovereignty reduces certain dependencies but is part of a broader strategy.
