T Cloud Public (known until January 2026 as Open Telekom Cloud) is Deutsche Telekom's public cloud, offered by T-Systems International. According to the provider, the platform is fully based on OpenStack and offers compute, storage, containers, AI, big data and managed services that you combine as needed. It targets companies, public bodies, healthcare, the financial and energy sectors, and research institutions across Europe. The provider reports certifications to ISO 27001, TISAX and BSI C5.
The provider presents the service as a sovereign cloud from Germany. According to the website, regions are operated exclusively in Europe: a twin-core region in Germany (Biere/Magdeburg), additional regions in the Netherlands and supplementary offerings in Switzerland. The provider states that data stays in European data centres, independent of non-European laws. The platform is not offered as open source but rests on open-source technology, which eases moving to other OpenStack environments. When choosing a region, check which location applies to your data.
