How data sovereignty is reshaping infrastructure decisions

Across the globe, the concept of data sovereignty has taken root as nations look to govern the data that is sent, processed, and stored within their borders. Driven by data residency concerns and growing regulatory pressures, governments are increasingly prioritising the funding of domestic AI infrastructure to ensure they own their data and to prevent any unauthorised intrusion from foreign bodies.

Some form of sovereignty or localisation framework has already been adopted by over 100 countries to ensure compliance with strict initiatives. But even then, sovereignty cannot be achieved through compliance alone. It’s imperative that data never leaves these trusted boundaries, meaning nations must now reassess the components present in their infrastructure.

The fight for data autonomy

The enactment of foreign legislation is a huge factor behind this increased desire for sovereign data governance. This includes the Clarifying Lawful Overseas Use of Data (CLOUD) Act – a piece of legislation passed in 2018 that empowers US authorities to access any data held by American companies regardless of the location it’s stored.

Naturally, this caused apprehension for US-based hyperscalers such as AWS, Meta, and Google Cloud operating in the EMEA and APAC regions. Organisations and governments quickly realised that data residency alone did not guarantee sovereignty, as jurisdiction could still follow the provider rather than the physical location of the infrastructure.

Another key catalyst for the migration to data sovereignty demand can be traced back to the United Kingdom in 2024, when Microsoft admitted to the authorities that it could not guarantee the sovereignty of policing data held in its cloud, even when that data was supposed to remain in the UK.

Initiatives such as GAIA-X and the EU Data Act have since taken shape to ensure these locally hosted services aren’t open to foreign access, and assert European countries’ rights to digital independence. They aim to improve data portability and protect data from unlawful foreign access requests, while increasing control over cloud data. Consequently, trusted locations for sectors such as security, finance, and healthcare are being created across the continent.

At the same time, enterprises and public-sector bodies have homed in on investment in localised infrastructure partnerships, encryption controls, and stricter governance frameworks. Plus, given that 72% of European businesses are prioritising sovereignty when it comes to choosing technology vendors, solutions that guarantee data stays within defined borders are now being seen as the standard-bearers of digital sovereignty.

Rethinking architecture

A critical part of this increased investment is fibre optics. Owing to their capacity to maintain optimal performance while traversing regionally controlled paths, they can deliver the locality essential in aligning with modern regulations, including EU sovereignty frameworks or national security laws. This starts with gaining physical control over the optics that shape the journey of data.

Many European governments and regulated enterprises are increasingly seeking more direct control over infrastructure procurement, including optics, to reduce hyperscaler dependence. Despite hyperscalers still dominating raw spending, driving a projected $700 billion in AI data centre infrastructure, nations are escalating their investment to ensure data residency. Look no further than the European Union’s €23 billion InvestAI initiative to create AI factories and supercomputing networks for an example of this.

Beyond providing the means necessary for sovereignty, optical infrastructure also holds the key to unlocking the elite levels of performance demanded by these AI and cloud infrastructures. These transceivers, cables, and optical pathways ensure the delivery of high bandwidth, low latency, and predictable performance while providing full oversight into data flows.

The challenge is now about balancing compliance, control, and performance simultaneously. With questions arising around the true sovereign intentions of hyperscalers, organisations are placing greater emphasis on trusted infrastructure partners that can provide transparency, interoperability, and operational ownership across critical connectivity layers.

The role of resilient optics

This balance is now being delivered by Network Equipment Manufacturer (NEM) alternative solutions providers. Guaranteeing compliance, security, and speed – and having already become trusted technology partners to global jurisdictions and organisations – the portfolios of solutions offered by these providers are enabling the evolution of infrastructure for the secure, scalable, and sovereign transfer of data.

This is partly due to their ability to be integrated across a wide range of vendor environments. Where businesses would have previously had to source and procure vendor-specific solutions, NEM alternative solutions like those offered by AddOn Networks can simply be plugged into existing platform. As a result, alternative optics can be deployed in mixed-vendor environments, empowering operators to avoid any form of vendor lock-ins to proprietary networks and align perfectly with sovereign initiatives.

Achieving the full value of data sovereignty requires overcoming cost challenges as well as technical complexity. Procurement is already simplified when electing NEM alternative optics, but so too are costs. Savings of up to 70% compared to NEM optics put suppliers such as AddOn Networks at the focal point of flexible, scalable, sovereign futures.

Ensuring sovereignty

In short, this increased focus on data sovereignty is pushing organisations to rethink their infrastructure to balance local control with global reach. It’s no mean feat, but with NEM alternative optical connectivity solutions that deliver the same level of compliance, sovereignty can be achieved without sacrificing performance.

Whether working with NIS2 architectures, DORA resilience strategies, or national digital sovereignty initiatives, one thing is for sure: fibre optics will help achieve regulatory piece of mind while maintaining operational excellence. Only then can a truly data sovereign framework be achieved.
