Kubernetes Established as the De Facto ‘Operating System’ for AI as Production Use Hits 82% in 2025 CNCF Annual Cloud Native Survey
Infrastructure Maturity is Near-Universal Kubernetes as the AI Platform GitOps and Platform Engineering Define ‘Innovators’ Observability is the Second Most Active Frontier Cultural Challenges Have Overtaken Technical Complexity What’s Next for Cloud Native New CNCF Annual Cloud Native Survey reveals near-universal adoption of Kubernetes Key highlights: The CNCF Annual Cloud Native Survey reveals that Kubernetes has solidified its role as the de facto ‘operating system’ for AI, with 82% of container users now running it in production environments. It confirms that Kubernetes is no longer an emerging technology but the established, reliable foundation for modern enterprise infrastructure, enabling companies to confidently scale and operationalize critical AI workloads.

Kubernetes Fuels AI Growth; Organizational Culture Remains the Decisive Factor
Kubernetes: From Infrastructure Choice to Infrastructure Standard AI Adoption Is Infrastructure-First What Mature Teams Are Doing: GitOps, Platforms, Observability Culture Is Now the Primary Barrier Looking Ahead: Infrastructure and Sustainability Posted on January 20, 2026 by Chris Aniszczyk, CTO, CNCF CNCF projects highlighted in this post The CNCF Annual Cloud Native Survey confirms a long-developing trend: Kubernetes has moved from container orchestration to becoming the backbone of modern infrastructure—including AI. Production usage of Kubernetes now stands at 82% among container users, and 66% of AI adopters are using it to scale inference workloads.

End-to-end recovery from AZ impairments in Amazon EKS using EKS Zonal shift and Istio
End-to-end recovery from AZ impairments in Amazon EKS using EKS Zonal shift and Istio Solution overview Prerequisites Walkthrough Create Aurora cluster with three reader endpoints, with each one in a different Availability Zone Create a three node EKS cluster in three different Availability Zones Deploy Istio Gateway, VirtualService, and sample application Zonal traffic shift run-book Restoring normal operations after the Availability Zone impairment is resolved Cleaning up Conclusion About the authors What happens when one of your Availability Zones (AZs) starts behaving badly, but doesn’t completely fail? Picture this: your Amazon Elastic Kubernetes Service (Amazon EKS) cluster is humming along across three Availability Zones when suddenly, an Availability Zone begins experiencing subtle performance degradation—not a complete outage, but enough to frustrate your customers with slower response times and intermittent errors. This scenario represents one of the most challenging problems in modern cloud architecture: gray failures.

Reclaiming underutilized GPUs in Kubernetes using scheduler plugins
The problem nobody talks about Kubernetes scheduling trade-offs for GPUs The core idea: Utilization-aware preemption Where ReclaimIdleResource fits in the scheduling cycle How it works Key design decisions What we learned Related Links Posted on January 20, 2026 by Lalit Somavarapha, Gernot Seidler and Srujana Reddy Attunuri, Principal Engineers at HPE CNCF projects highlighted in this post GPUs are expensive; and yours are probably sitting idle right now. High-end GPUs (for example, NVIDIA A100-class devices) can cost $10,000+, and in a Kubernetes cluster running AI workloads, you might have dozens of them.

Uniform API server access using clientcmd
Uniform API server access using clientcmd General philosophy Available features Configuration merging Overall process Configure the loading rules Configure the overrides Build a set of flags Bind the flags Build the merged configuration Obtain an API client Full example If you've ever wanted to develop a command line client for a Kubernetes API, especially if you've considered making your client usable as a kubectl plugin, you might have wondered how to make your client feel familiar to users of kubectl. A quick glance at the output of kubectl options might put a damper on that: "Am I really supposed to implement all those options?" kubectl kubectl kubectl options Fear not, others have done a lot of the work involved for you.

The New Baseline: Modern Systems Assume Kubernetes Kubernetes Solved the Problem Containers Couldn’t New to Kubernetes? Kubernetes Is an Operating System for Distributed Applications Want to Understand Kubernetes Deeper? Kubernetes Forces You to Think Like a Systems Engineer The Real Takeaway: Kubernetes Is a Career and Architecture Multiplier New to Kubernetes and Want a Practical Start? Ready to Build Real Kubernetes Skills? FAQs Join 1M+ Learners Why Continuous Learning Is the Only Job Security in Tech Top Myths About Learning Cloud Skills (and the Truth Behind Them) From Scattered Learning to Structured Growth: Inside KodeKloud Cohorts Why Career Switchers Are Flocking to Tech & Cloud Roles How to Change Hostname on Linux (Without Rebooting) Is Cloud the Future of All IT Roles? You might not be the one writing Helm charts or tuning kube-scheduler flags. But chances are high that: The application you deploy runs on Kubernetes The CI/CD pipeline targets a Kubernetes cluster The monitoring, security, or networking tooling expects Kubernetes primitives The production issues you debug surface as Kubernetes behavior This is the quiet shift many engineers miss.
