Overview

With NATO members committing to increase defence spending to 5% of GDP, the Alliance is entering a new phase of technological modernisation. As governments seek to translate investment into real capability, digital infrastructure has become central to operational readiness, intelligence sharing and decision-making.

Cloud computing sits at the heart of this transformation. It offers the potential to improve speed, scale, and collaboration – but also raises complex questions about data sovereignty, security, and trust between allies. How can nations maintain sovereign control over sensitive systems while ensuring interoperability and cohesion across the Alliance?

In this keynote and fireside chat, Jean-Charles Ellermann-Kingombe will reflect on NATO’s digital transformation agenda and how the Alliance views national sovereignty and collaboration to strengthen collective resilience in an era of rapid technological change.

This event is part of RUSI’s Cloud Sovereignty Project, which aims to establish a common language about cloud sovereignty and examine how existing approaches impact national security.
