Open Telekom Cloud — Enterprise sovereign cloud in Germany
Open Telekom Cloud is the sovereign-cloud offering of Deutsche Telekom, operated by its enterprise services arm T-Systems. The platform is OpenStack-based and operates from German data centres in Biere (Saxony-Anhalt) and Magdeburg, with additional European locations. Open Telekom Cloud is positioned as a German-sovereign alternative to AWS, Microsoft Azure and Google Cloud for customers whose risk preference, regulatory environment or data-protection posture requires contractual jurisdiction inside Germany and operational control by a German-headquartered provider. For ERP buyers Open Telekom Cloud is relevant in scenarios where data sovereignty is a structural requirement that hyperscalers cannot fully satisfy: regulated industries (defence, financial services subject to BaFin scrutiny, parts of healthcare), public-sector organisations and Mid-Market customers in sensitive supply-chain positions. The platform is SAP-certified for HANA workloads and is one of the few European-headquartered cloud providers with serious enterprise scale.
About
Open Telekom Cloud is operated by T-Systems International GmbH, a subsidiary of Deutsche Telekom AG headquartered in Frankfurt. The platform was launched in 2016 and has been progressively expanded with additional services, capacity and regional presence. Core data centres operate in Biere and Magdeburg in eastern Germany, with additional European locations including the Netherlands and Switzerland. The platform is built on OpenStack and reuses elements of the open-source cloud-platform technology developed in cooperation with Huawei, while operating fully under T-Systems control and German jurisdiction. Compliance posture includes BSI-C5 attestation, ISO 27001, ISO 27017, ISO 27018, EU Cloud Code of Conduct, German TCDP (Trusted Cloud Data Protection) and selected sector-specific certifications relevant to public administration and financial services. The provider holds SAP-certified status for HANA infrastructure and is a recognised hosting option for SAP customers seeking German sovereign deployment.
Service offering
The Open Telekom Cloud service catalogue covers the standard IaaS and PaaS layers: Elastic Cloud Server (virtual machines including SAP HANA-certified instance types), Elastic Volume Service (block storage), Object Storage Service (S3-compatible), Virtual Private Cloud (networking), Cloud Container Engine (managed Kubernetes), managed databases, dedicated bare-metal servers and identity-management services. SAP HANA-certified instances support self-managed SAP S/4HANA Private Cloud deployments and are referenced by SAP for sovereignty-sensitive scenarios. Adjacent services include data-protection-aware analytics offerings, AI services running inside the German cloud boundary, and a managed-service layer where T-Systems operates the customer's workloads. For ERP buyers the typical deployment pattern is a partner-led SAP S/4HANA migration where Open Telekom Cloud is selected as the infrastructure provider, with the customer or a partner operating the SAP application layer.
DACH positioning
In the DACH cloud market Open Telekom Cloud is one of the two or three serious German-sovereign hyperscaler alternatives alongside IONOS Cloud and STACKIT. The provider's differentiator is the combination of T-Systems' enterprise-services heritage with full German jurisdiction and a relatively mature service catalogue that goes beyond pure compute and storage. For SAP customers in regulated sectors, Open Telekom Cloud is one of the few platforms that combines SAP HANA certification with German sovereign operation, which makes it the natural choice for scenarios where U.S.-headquartered hyperscalers create a contractual concern. Compliance posture covers GDPR by default, BSI-C5, the EU data-protection framework and German-specific sector regulations. German-language sales, account management and enterprise support are available throughout the customer lifecycle. The partner ecosystem for SAP-on-Open-Telekom-Cloud is smaller than for the global hyperscalers, but several large DACH SAP partners support it as a deployment target.
Strengths and selection considerations
Strengths to consider: German jurisdiction and full German operation, BSI-C5 attestation, SAP HANA certification, T-Systems' enterprise heritage including 24/7 German-language support, and a structurally sovereign positioning that addresses the U.S. CLOUD Act concern for highly regulated customers. For regulated-sector customers, public administration and Mid-Market customers with explicit sovereignty preferences, Open Telekom Cloud is a credible choice for SAP and non-SAP workloads. Limitations to consider: the service catalogue is narrower than AWS, Azure or Google Cloud — customers should not assume one-to-one feature parity, and workloads relying on hyperscaler-specific managed services may not port cleanly. Pricing is closer to enterprise-grade than to commodity hyperscaler pricing, particularly when combined with managed-service layers from T-Systems. The partner ecosystem for SAP-on-OTC is smaller, so finding implementation partners with deep OTC experience may require explicit search. For Dynamics 365 SaaS workloads the platform is not relevant.

Frequently Asked Questions
Is Open Telekom Cloud SAP-certified?
Yes. Open Telekom Cloud has SAP HANA-certified instance types and is referenced by SAP for sovereignty-sensitive deployments. Self-managed SAP S/4HANA Private Cloud deployments on Open Telekom Cloud are supported, and several large DACH SAP partners include the platform in their hyperscaler-target portfolio. Rise with SAP commercial bundles can be structured with Open Telekom Cloud in specific deal constructions.
Is data on Open Telekom Cloud subject to the U.S. CLOUD Act?
No, materially less than for U.S.-headquartered hyperscalers. T-Systems International GmbH is a German company under German jurisdiction, and Deutsche Telekom is a German parent group with limited U.S.-affiliate exposure for the cloud business. The structural sovereignty position is one of the core reasons regulated-sector customers select Open Telekom Cloud over AWS or Azure. Customers should still review the specific contractual data-protection commitments for their scenario.
How does Open Telekom Cloud compare with IONOS Cloud?
Both are German-headquartered sovereign-cloud platforms with comparable jurisdiction and compliance positioning. Open Telekom Cloud is OpenStack-based and operated by T-Systems with enterprise-services heritage, typically targeting larger regulated customers. IONOS Cloud is built on its own infrastructure stack and is positioned as a hyperscaler alternative for Mittelstand customers. Choice depends on specific service-catalogue fit, existing supplier relationships and pricing in the customer's scenario.
