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.

Why Kubernetes Is a Must-Know for Modern Engineers
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.

Kubernetes Networking at Scale: From Tool Sprawl to a Unified Solution
The Components of Kubernetes Networking Hybrid Cloud Deployments – One Platform, Two Networking Models AI Workloads as a Key Driver of Hybrid Cloud Adoption Hybrid Complexity Compounds Operational Risk Hidden Cost of Disconnected Tools The Need for Integration Characteristics of an Integrated Kubernetes Networking Solution The Path to Predictable, Secure Networking Simplify Your Kubernetes Networking As Kubernetes platforms scale, one part of the system consistently resists standardization and predictability: networking. While compute and storage have largely matured into predictable, operationally stable subsystems, networking remains a primary source of complexity and operational risk This complexity is not the result of missing features or immature technology.

Moving Beyond Kyverno to AI Platform Engineering
Moving Beyond Kyverno to AI Platform Engineering Kyverno OSS – Excellent Starting Point But Not The End Game Nirmata Enterprise for Kyverno – Kyverno Made Enterprise-Ready Centralized, Scalable Governance Enterprise-Grade Reliability Professional Support & Policy Best Practices AI-Powered Platform Engineering Assistance Remediator AI Agent: From Alert to Fix Command Line AI: Your Policy-as-Code Copilot When Does AI Platform Engineering Make Sense Over Kyverno A Practical Example Self-Service Control – AI as the Enabler, Not the Gatekeeper Trusting AI in the Platform: Reliability, Safety & Control AI That Supports Platform Engineers The Real Business Impact Improve Developer Velocity Strengthen Security and Compliance Scale Without Adding Headcount Reduce Operational Risk Bottom Line As platform engineers, most of us have been there: wrestling with hundreds of Kubernetes clusters, trying to enforce consistent security, compliance, and operational policies, all while balancing developer velocity and team efficiency. If you’ve relied on open-source Kyverno, you already know how powerful policy-as-code can be for Kubernetes governance.
