About T Cloud Public (formerly Open Telekom Cloud)
T Cloud Public is the public-cloud platform of Deutsche Telekom AG (Germany's largest telecoms group), operated by T-Systems International GmbH (the enterprise-IT and consulting subsidiary headquartered in Frankfurt am Main). The service was launched in 2016 as Open Telekom Cloud (OTC) and was rebranded to T Cloud Public in 2026; the open-telekom-cloud.com domain now 301-redirects to t-cloud-public.com. The platform is OpenStack-based with open APIs that enable straightforward portability of workloads in and out, runs in a Twin-Core high-security data-centre region in Biere and Magdeburg (Saxony-Anhalt, Germany), and offers additional regions in the Netherlands and Switzerland for buyers needing geographically diverse EU/EEA-and-adequacy placement.
Compliance posture is among the strongest in the directory. T Cloud Public carries ISO/IEC 27001, ISO 27017, ISO 27018, the German government's BSI C5 Cloud Computing Compliance Criteria Catalogue, and TISAX (the German automotive supply-chain security framework), a combination unusually well-suited to regulated public-sector and DACH-automotive procurement. The product positions itself as "full sovereignty: data stored in European data centres, GDPR-compliant and independent of non-European laws." T-Systems' broader enterprise-services book also supports IT-Grundschutz, DORA-readiness for financial services, and a wide range of public-sector frameworks. Customer base spans Deutsche Telekom's enterprise verticals (healthcare, public sector, research, automotive, media, retail), and OpenStack interoperability makes it a natural target for migration projects out of AWS/Azure/GCP that need an EU-sovereign destination.
Pricing is pay-as-you-go with €250 starting credit for new customers; specific compute-instance entry-tier EUR figures were not captured at audit (the public price page directs to a calculator and PDF). Support is included in the base price with 24/7 phone availability in DE and internationally. Best fit: large DACH enterprises, German public-sector procurement (especially those already in the Deutsche Telekom commercial relationship), DORA-regulated financial services, TISAX-required automotive supply chains, and any EU buyer wanting a Deutsche-Telekom-grade enterprise OpenStack alternative to AWS / Azure / GCP. Together with Hetzner, OVHcloud, Scaleway, IONOS, UpCloud, STACKIT, Cleura, and Exoscale, T Cloud Public completes the procurement-grade EU hyperscaler-alternative stack on this directory.
