•STACKIT's EU cloud accessible through BT Global Fabric network-as-a-service platform
•Data stays in the EU but access extends globally through BT's private connections
The fact
BT International has partnered with STACKIT, the cloud platform of Schwarz Group — Europe's largest retailer — to provide global connectivity to its EU-based sovereign cloud service. Initial access will be delivered through internet peering via BT's Global Fabric network-as-a-service platform, with private connectivity planned. STACKIT operates data centres in Germany under EU GDPR frameworks, enabling non-EU enterprises to access compliant cloud infrastructure through BT's global network.
The Assessment
The partnership addresses a specific gap in sovereign cloud markets: enterprises that need EU-hosted, GDPR-compliant infrastructure but operate across jurisdictions. STACKIT benefits from BT's global network reach rather than having to build direct connectivity itself. For BT, sovereign cloud partnerships are a differentiation play in the increasingly commoditised NaaS market — stacking network-as-a-service with cloud-as-a-service. The model mirrors similar telco-cloud partnerships in Asia and the Middle East, where local sovereignty requirements intersect with multinational operational footprints.
What to Watch
Whether STACKIT's EU data residency model attracts non-EU customers facing similar sovereignty requirements — such as UK firms post-Brexit or Middle East enterprises — and if BT replicates the partnership template with other regional cloud providers.
