Open Telekom Cloud / T Cloud Public (otc)
This page describes the Landing Zone catalogue otc as shipped with SWAO: the provider and its sovereignty model, the regions with their residency and certifications, how the catalogue is refreshed and how to use it as a target.
Provider and sovereignty model
Open Telekom Cloud, now marketed as T Cloud Public, is the public cloud of T-Systems International GmbH, a Deutsche Telekom subsidiary. The provider ID stays otc. The catalogue covers the regions eu-de (Germany) and eu-nl (Netherlands), each with three availability zones.
Sovereignty model: the operator is an EU entity without a US parent, so no extraterritorial exposure is recorded. Both regions record BSI C5, ISO/IEC 27001 and SOC 2. Offerings of T Cloud Public outside these two regions are not covered by this catalogue.
