The strategic rationale is clear: Europe wants to create digital infrastructures that are not only high-performing, but also controllable, auditable and manageable in accordance with European legal and operational conditions. The aim is to reduce technological dependencies, increase freedom of choice and make digital infrastructures more resilient. 8ra therefore describes digital sovereignty not as a buzzword, but as a verifiable capability across four dimensions: data sovereignty, technological sovereignty, operational sovereignty and legal sovereignty. Behind this lies a very practical aim: workloads should remain transferable between providers and locations, data flows should be controllable in a transparent manner, and services should remain functional and manageable even in the event of provider changes, disruptions or crises.

Edge and cloud belong together

8ra’s real strength lies in no longer treating cloud and edge computing as two separate worlds. In many industrial and public sector scenarios, a purely centralised cloud model is insufficient: latencies are too high, data volumes too large, regulatory requirements too strict and failure scenarios too critical. 8ra therefore relies on a distributed continuum in which computing power and services are provided where they make the most sense from both a business and technical perspective. This can be central clouds, regional infrastructures or the direct network edge. This enhances performance and resilience, reduces structural lock-in risks and lays the foundation for applications such as industrial real-time processing, edge AI or federated data spaces.

In doing so, it also addresses key European market challenges. Unlike the US or China, Europe is grappling with a fragmented provider landscape and a lack of interoperability amongst many solutions. The resulting high dependence on dominant overseas platforms has only exacerbated this problem, making it difficult for small and medium-sized providers to integrate into a resilient ecosystem.

More than just an architectural concept

These challenges make the 8ra architecture more than just a technical ideal. It is an industrial policy programme aimed at creating a technological space that has an impact beyond individual solutions. At the 8ra Annual Summit 2026 in Rotterdam, the focus was therefore no longer solely on fundamental research, but on the next phase: implementation, scaling and market integration. Europe is now discussing 8ra not merely as a research programme, but as an infrastructural response to the question of how digital operational capability can be organised in practice within cloud, edge and, in future, AI environments.

This is precisely where secunet brings its nearly 30 years of cybersecurity experience to bear within the 8ra initiative. secunet’s contribution aims to ensure that edge-to-cloud infrastructures are not only functional, but also highly secure and operationally manageable. Right from the start of the initiative, the secunet edge cloud project was launched to develop, in collaboration with partners, highly secure, automatically networking edge-cloud infrastructure modules that can also be deployed in critical infrastructure. The technological foundations for this have now been laid.

secunet edge cloud: Security and computing power at the network edge

One of secunet edge cloud’s initial priorities was high-security modules for cloud infrastructures, particularly for scenarios with stringent regulatory requirements. Client isolation, trust anchors, cryptographic protection mechanisms and secure orchestration and operational processes are not merely additional features, but form part of the architectural foundation. This foundation is based on reusable security building blocks. Security is therefore not added to a platform as an afterthought, but is integrated from the outset through principles such as ‘design-by-compliance’ and ‘security-by-default’. This is particularly crucial in a multi-provider environment: anyone wishing to create federated infrastructures needs common security principles, standardised interfaces and verifiable baselines.

Equally important, however, is the second aspect of the project: the edge itself. To this end, a modular edge node platform has been developed which brings computing power, security functions and platform services directly ‘to the network edge’ – that is, to where machines, devices and gateways operate. Robust, secure edge architectures enable local data processing even with limited connectivity, in distributed operating models and under high requirements for availability, data protection and real-time capability. This approach also makes it possible to run applications such as edge AI, security functions or industrial services close to where the data is generated.

However, these components alone are not enough if development and operational processes do not scale up just as quickly and securely. That is why secunet has established an Internal Developer Platform (IDP) as part of the project, which brings together DevSecOps principles, standardised toolchains, defined interfaces and platform services. This approach is primarily strategic: development, operations and security requirements are thus not handled in separate ‘silos’, but are accelerated on a common basis and standardised across product and project boundaries. This creates the conditions for rapidly putting new edge and cloud functions into practice and for facilitating collaboration with partners within a heterogeneous European ecosystem.

From reference architecture to application

The 8ra initiative is currently making visible progress from the architectural and reference level towards practical application. Now that the technological foundations have been laid, the focus is shifting more strongly towards the transition to market-ready edge-to-cloud scenarios. secunet has already established the organisational framework for this. In cooperation with partners, this will result in robust managed cloud and edge architectures that connect sovereign data centres, hybrid infrastructures, as well as machines, devices and critical network segments. This is not a loose collection of technologies, but an integrated, multi-tenant and operationally manageable end-to-end system. The scope ranges from the secure digitisation of existing systems, through the connection of distributed sites, to interoperability between modern platforms and legacy systems, edge security solutions and local AI processing.

8ra thus highlights what digital sovereignty in Europe means in practice: not isolation, but controllable openness. Not a single provider, but an interoperable ecosystem. And not just architectural principles, but real-world operability. The initiative creates a European framework for action in which digital infrastructure becomes open, secure and independent enough to be viable in the long term.
