Open Telekom Cloud (T Cloud Public)
The Open Telekom Cloud — rebranding to T Cloud Public in 2026 — is Deutsche Telekom's sovereign public cloud, operated by its enterprise arm T-Systems. It positions itself as a "sovereign cloud from Germany" and layers AI Foundation Services on top for enterprises that want managed LLM capabilities under European jurisdiction.
Compliance is a core selling point: the platform is "certified according to ISO 27001, TISAX & BSI C5", and its AI services are "subject to sovereign, secure, and legally compliant regulations of the European Union with GDPR compliance and data sovereignty ensured". Services run in Telekom data centres in Germany, the Netherlands and Switzerland.
As one of Europe's largest telcos, Deutsche Telekom offers reassurance to public-sector and regulated buyers who prefer a national champion. It also partners with Google Cloud on a separate sovereign offering, underscoring T-Systems' role as a European data trustee.
