Open Telekom Cloud – The cloud platform of Deutsche Telekom AG

Earth with lights at night

The Open Telekom Cloud of Deutsche Telekom AG was launched in 2016 and developed into a solid cloud platform since then. The Open Telekom Cloud platform offers many services on top of the standard IaaS set, e.g. for data analytics and for serverless functions.

The technology of Open Telekom Cloud is based on the Huawei “distro” of OpenStack called Huawei FusionSphere. Parts of the hardware for Open Telekom Cloud is also provided by Huawei. Some observers are therefore raising questions about true sovereignty of Open Telekom Cloud. Does Huawei possess a kill switch for Open Telekom Cloud? Is a US dependency simply traded for a dependency on a Chinese supplier? At least the spectrum of suppliers and dependencies is widened.

Features & Services

Open Telekom Cloud has a very broad service portfolio, including some unique services, e.g. for Big Data processing, the AI service ModelArts, an OCR service and the serverless compute engine FunctionGraph, a Service Mesh, a Data Warehouse and many more advanced services.
