As data sovereignty becomes a growing priority for data centres across Europe, Iwona Zalewska, Regional Director for UK & Ireland and DRAM Business Manager for the EMEA Region at Kingston Technology, explains why infrastructure decisions now matter more than ever.

Data sovereignty has become a defining priority for data centres across Europe, reshaping infrastructure requirements and increasing the focus on compliance, transparency and resilience – not just performance or capacity. The need to keep sensitive information within EU borders and comply with regulations such as GDPR and the Data Act means that companies must address where and how their data is stored, processed and protected.

In the EU, data sovereignty typically means that data generated in the EU must remain governed by EU laws, standards and regulatory frameworks, regardless of where it is stored or processed. At its core, it’s about ensuring that European citizens, businesses and public institutions can maintain control over their data without interference from outside jurisdictions.

It goes far beyond basic GDPR compliance, covering how personal and non-personal data is accessed, how it moves across borders and which cloud or infrastructure providers have legal authority over it. More recent legislation, such as the Data Act, the Data Governance Act (DGA) and NIS2, further reinforces sovereignty by promoting transparent, interoperable, EU-based infrastructure and reducing dependence on global hyperscalers.

Data residency should not be confused with data sovereignty; it refers to where data is physically stored, such as on servers in Spain. Data sovereignty determines which legal framework governs that data, regardless of its physical location. This is important if an organisation uses non-EU cloud or SaaS providers. The data may be stored in EU-based data centres, but it could fall under extraterritorial jurisdiction if the provider is headquartered outside the EU. Understanding this difference is essential for enterprises managing sensitive or regulated information.

The data sovereignty framework

Let’s look at the regulations that make up the framework in the EU:

The General Data Protection Regulation (GDPR) is the cornerstone of the EU’s data protection policy. As well as protecting consumer privacy, GDPR plays a critical role in data residency, cross-border data flows and what constitutes a lawful transfer of personal data.

Companies using global cloud platforms must work within GDPR’s strict obligations around transparency, consent, breach notification and third-country data transfers.

The Data Governance Act is a framework for sovereign data governance and secure data-sharing mechanisms across the EU. It introduces trusted intermediaries, data-sharing services and structures such as data cooperatives and data trusts, aimed at making cross-sector data exchange safer and more transparent. The DGA signals that future digital services will rely on EU-governed data spaces.

The EU Data Act ensures fair access, data portability and clear rules on how industrial and non-personal data generated by connected devices can be used. It encourages the adoption of EU-based cloud providers, reduces the risk of vendor lock-in and sets strict conditions for transferring industrial data to non-EU jurisdictions.

The broader European Strategy for Data underpins the push towards EU digital sovereignty, aiming to create interoperable, secure Common European Data Spaces across sectors such as manufacturing, mobility, health and energy.

The practical impact on data centres

Within data centres, performance, capacity and cost are still essential, but sovereignty, governance and control are becoming key deciding factors when choosing storage, compute and network infrastructure.

The focus for EU data centres is to enable technical design and legal obligations to work together, which means that infrastructure teams must ensure every layer of the stack aligns with sovereignty standards while optimising for speed or density.

The practical implication is that sovereign cloud environments must be built where data is processed and governed entirely within EU jurisdiction. A hybrid approach could involve the use of hyperscalers, but sensitive workloads must remain fully EU-hosted. ‘EU-only’ service tiers may need to be adopted, and full transparency over data movement, including logs, telemetry, backups and failover paths, is now critical.

The importance of storage

Storage infrastructure plays a central role in ensuring that data remains verifiable, protected and governed by EU law. As a result, data centres are placing greater emphasis on the capabilities of the drives and systems they deploy.

These include self-encrypting drives that protect data at rest without relying on software-level encryption, making them particularly relevant for sovereign cloud environments. In addition, power-loss protection (PLP) helps reduce the risk of data corruption during unexpected outages. This is particularly important for regulated environments, such as finance, public sector administration and healthcare.

Facilities are becoming increasingly focused on end-to-end data integrity to keep data intact across the entire pathway, from the moment it’s written to long-term retention. Many are also moving towards sovereign cloud models to ensure consistent performance under heavy load. Storage must support enterprise-level write cycles, low latency and long operational lifespans.

Building a compliant data strategy

The need to comply – and the risks of non-compliance – are changing how organisations think about storage, cloud services and data governance. With new regulations strengthening the EU’s control over personal and industrial data, it is essential for companies of all sizes to have clarity over where their data lives, who can access it and which laws ultimately apply.

One of the most fundamental elements of compliance for data centres and enterprise infrastructure teams is prioritising technology that supports compliance at the hardware level: built-in encryption, protection against power loss and end-to-end data integrity.

Infrastructure decision-makers and specifiers must ensure that their organisation’s storage, backup and cloud practices keep their data fully under EU legal protection. Reinforcing data sovereignty goes beyond technical choices alone. It reflects a deeper responsibility to protect sensitive information and to work with partners and third parties whose standards, accountability and commitments support that goal.
