Private cloud technology is experiencing a significant revival, driven by artificial intelligence and digital sovereignty needs. At the recent KubeCon + CloudNativeCon Europe 2025 in London, attendance soared to 12,000 participants, demonstrating that Kubernetes and cloud-native technologies remain essential infrastructure components in the AI era. This renewed interest marks a shift from the hybrid cloud focus of recent years, as companies seek greater control over their data while building AI capabilities.
The big picture: Kubernetes and cloud-native technologies are proving remarkably resilient against AI displacement while simultaneously becoming foundational for AI infrastructure development.
- The technologies that underpin modern cloud deployments require expertise and understanding of complex systems that current AI models struggle to replicate accurately.
- OpenAI has been building its systems on Kubernetes since 2016, highlighting how these technologies are fundamental to the AI revolution.
Why this matters: Private cloud implementations are regaining prominence after years of being overshadowed by public and hybrid cloud strategies.
- This represents a significant shift from recent years when some major vendors had stopped mentioning private cloud in their client discussions.
- The maturity of modern private cloud implementations now offers businesses the agility of public cloud with enhanced control and security.
Key drivers: Two major trends are fueling the private cloud renaissance.
- AI development requires businesses to protect valuable proprietary data when building small language models or conducting internal inferencing, making public cloud AI solutions insufficient.
- Growing concerns around digital sovereignty are pushing organizations to deploy modernized private cloud infrastructures to maintain data integrity amid global uncertainty.
Reading between the lines: The packed attendance at a 10-year-old conference suggests cloud-native technologies aren’t simply maturing—they’re evolving to meet emerging enterprise needs.
- The author initially expected KubeCon to show signs of decline given the event’s age and AI’s impact on development, but instead found unprecedented enthusiasm.
- This contradiction reveals how foundational technologies like Kubernetes are adapting to support rather than compete with AI advancement.
Where we go from here: The continued relevance of Kubernetes and cloud-native technologies appears secure as they become essential components of AI infrastructure.
- The author suggests watching the upcoming KubeCon event in Atlanta to determine if this growth trend continues.
- As businesses modernize infrastructure while prioritizing data protection and AI implementation, cloud-native approaches will likely remain central to enterprise strategy.
