Rising AI demand and sovereignty requirements are changing infrastructure choices, ISG Provider Lens^® report says

German enterprises are redesigning private and hybrid cloud environments to support AI workloads while achieving greater control over sensitive data and managing new operational requirements, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2026 ISG Provider Lens^® Private/Hybrid Cloud — Data Center Services report for Germany finds that data center strategies are changing as AI becomes embedded in infrastructure environments. Computing requirements are increasing while regulation and energy shortages place tighter constraints on capacity, location and governance.

"German enterprises can no longer treat AI as a separate technology layer," said Matthias Paletta, director at ISG. "It needs to be integrated with the entire stack. Organizations are redesigning infrastructure and operating models for performance, control and accountability in the age of AI."

IT operations in German organizations, across on-premises and cloud infrastructure, are shifting from reactive maintenance toward predictive and increasingly autonomous models. AI-enabled monitoring helps teams detect anomalies and anticipate maintenance needs, while GenAI copilots and self-service interfaces simplify troubleshooting and capacity planning.

German companies are reconsidering where workloads run as hyperscalers raise costs and change licensing terms and new data-control requirements emerge. Increasingly, they place sensitive systems in private or hybrid environments, using public clouds selectively for scalable services. This approach is especially important in regulated sectors that require local control and traceable governance.

Germany’s industrial enterprises are adding edge infrastructure to hybrid cloud architectures to process data close to factories and other operating sites. Local AI inference supports time-sensitive applications that cannot rely on round trips to centralized data centers. Enterprises increasingly expect edge environments to operate under the same management and governance model as core and cloud infrastructure.

As AI computing becomes more power intensive, sustainability is becoming a formal criterion for infrastructure sourcing. German enterprises increasingly assess colocation providers based on their ability to support high-density systems and provide clear data on energy and water efficiency. These measures help organizations compare expansion plans against environmental reporting requirements, ISG says.

"German enterprises increasingly expect proof of private and hybrid cloud consumption, cost and compliance," said Ulrich Meister, lead author of the report. "Providers that make these factors transparent across hybrid environments will be better positioned to support informed infrastructure decisions."

The report also explores other public and hybrid cloud trends in Germany, including provider consolidation and the growing importance of partnerships among colocation operators, managed services providers and telecommunications companies.
