Detailed Review
T Cloud Public is the name since January 2026 of the platform formerly called Open Telekom Cloud, run by T-Systems International GmbH in Frankfurt (HRB 55933). Its Object Storage Service, OBS, is reachable over REST APIs and the S3 protocol.
The service page lists three classes: standard for frequent access, warm for roughly monthly access with a 30-day minimum, and cold for archives with a 90-day minimum.
Classes and Durability
All three classes are spread over three availability zones. Standard and warm are listed with durability up to 12 nines and 99.95 percent availability, cold with 11 nines. Cold retrieval takes minutes with expedited access and 3 to 12 hours in the standard and bulk modes.
Protection Features
The page lists versioning, lifecycle rules, bucket and object policies, IAM, default bucket encryption through the platform key management service and logging with event notifications. Object lock is mentioned for protection against ransomware, and cross-region replication appears in the release notes as a new feature.
Pricing Is Not on the Page
The product page links to a price calculator and a service description PDF instead of listing rates. A starting credit of EUR 250 is offered for bookings until 31 December 2026.
Limitations to Consider
No storage price appears on the product page, so comparing it with flat-rate providers needs the calculator or the PDF. The feature list is aimed at enterprise cloud projects, and the platform renamed in 2026, so older documentation and integrations may still use the Open Telekom Cloud name. Cold retrieval takes hours.
Who Should Use T Cloud Public
Enterprises and public bodies that already contract with Deutsche Telekom or T-Systems and want S3 access inside the same platform.
