T-Systems Sovereign Cloud powered by Google Cloud
This offering pairs Google Cloud's technology with T-Systems as the sovereignty operator — "the first of its kind on the German market", which "offers compliance with the requirements of German regulators, while retaining the public cloud functionality of a hyperscaler". It is a data-trustee model: T-Systems, a Deutsche Telekom subsidiary, runs a "Security Operations Center (SOC) outside of platform" and manages sovereignty controls such as encryption and identity, with a Germany Data Boundary.
Like the AWS and Microsoft sovereign clouds, it should be classified as hyperscaler-sovereign — the underlying platform is Google's — but the German data-trustee structure gives public-sector and regulated buyers additional operational assurance that a US operator cannot unilaterally access data.
AI capabilities are expanding as more Google Cloud AI services gain sovereign controls, making this a route to Gemini-class models under German operational oversight.
