A managed, EU-sovereign Kubernetes cloud by T-Systems — built on open-source Gardener and IronCore, integrated into the NeoNephos ecosystem.
Designed, built and operated in the EU, Open Sovereign Cloud gives organizations greater control over data location, platform operations and technology choices. Its open, transparent architecture reduces external dependencies and strengthens digital autonomy.
Powered by Gardener, Open Sovereign Cloud (OSC) automates provisioning, upgrades, scaling and lifecycle management for Kubernetes clusters. Customers focus on applications while OSC operates the underlying platform and control planes.
Customer workloads run on dedicated physical compute hosts, separated from other tenants at the infrastructure level. OSC manages the hardware and virtualization while customers consume flexible, managed Kubernetes resources.
Hardware-backed trusted execution environments protect sensitive data and code during runtime. Attestation ensures workloads run only in an approved and verified environment before secrets are released.
OSC is built on open-source technologies and standards-based Kubernetes. Open APIs and transparent components reduce vendor lock-in and keep workloads aligned with the wider cloud-native ecosystem.
OSC builds on Gardener and IronCore within the NeoNephos ecosystem under Linux Foundation Europe. Customers benefit from shared European innovation, open standards and a roadmap independent of proprietary hyperscalers.
