Sovereignty or Illusion?
An open letter from 25 European cloud and digital companies reveals what European digital policy has been avoiding for years: The term "digital sovereignty" is consistently used without its prerequisites being met.

France's Open Source Strategy
Since 2021, the French government has been pursuing a well-structured approach to the digital transformation of the state with the action plan "Free Software and Digital Commons." Open Source is not treated as a technical detail but as a strategic tool to strengthen state capabilities and technological independence.

Kubernetes as the Foundation of Digital Sovereignty
Digital sovereignty is often discussed in abstract terms, but it can be technically delineated quite clearly: the key is what systems are bound to. Once applications depend on specific infrastructures, proprietary APIs, or non-standardized operating models, a coupling arises that can only be resolved later with significant effort. In practice, this means that many architectures are formally portable but are not actually moved.
Kubernetes Image Promoter:
It's often not the visible features that determine the stability of modern platforms, but the inconspicuous systems in the background—those components that must function reliably without attracting attention. One such system is the focus of a recent post from the Kubernetes Blog: the **Kubernetes Image Promoter**—and its comprehensive, deliberately "invisible" redevelopment.
AI Gateway in the Kubernetes Ecosystem:
The discussion around AI infrastructure is noticeably shifting: away from mere model questions, towards the real challenge of how AI can be integrated into existing platforms in a controlled, secure, and efficient manner. A recent post from the Kubernetes Blog on the new **AI Gateway Working Group** provides an insightful impetus for this – and makes it clear that the Cloud-Native world is already preparing for the next generation of architecture.
CloudFest 2026
CloudFest is one of the few events where the term "industry meeting" is not an exaggeration. This is where the layer of IT that builds, operates, and sells infrastructure comes together. Anyone who wants to understand where hosting, cloud, and platform economy are heading cannot miss this event.

Breaking Free from Vendor Lock-in: Strategies for a Sovereign Cloud Migration
Migrating from centralized hyperscaler platforms to modern decentralized architectural approaches requires precise planning and execution. Best practices include a thorough analysis of the existing infrastructure, selecting appropriate tools and techniques, and comprehensive team training. Key pitfalls include inadequate data migration, lack of testing, and ignoring security aspects. Companies that proactively address these challenges can successfully reduce dependencies and significantly optimize their cloud migration.
Security Aspects in Modern Cloud Architectures: An Integrative Approach
Security in cloud architectures is a critical factor for companies utilizing digital technologies. Growing demands for compliance, data integrity, and risk management pose significant challenges for integrators. This article highlights the key security aspects companies must consider to ensure the safety of their cloud environments. By adopting an integrative approach that combines technological and organizational measures, companies can develop effective security strategies to address the highly dynamic threats in the cloud.
Optimizing Infrastructure with Declarative Operating Models
Declarative operating models provide companies with an effective method for automating and standardizing complex infrastructure management processes. Compared to centralized hyperscalers, they offer greater flexibility, robustness, and digital sovereignty. By focusing on describing the desired state rather than implementation details, efficiency is increased, and compliance requirements can be better met. Companies benefit not only from cost reductions but also from improved responsiveness to changing needs.
