Beyond Ingress Part II: Securing East-West Traffic with GKE Internal Gateway
https://medium.com/@bgillman_83663/beyond-ingress-part-ii-securing-east-west-traffic-with-gke-internal-gateway-7aef950aafe2
This article will also focus on GKE Gateway, but now we're going to explore Internal Regional Gateway for load balancing east-west traffic (i.e. service-to-service) to your application. Leveraging our learnings from my previous post, we'll include the GKE external gateway in this architecture while using the Internal Regional Load Balancer gatewayclass (gke-l7-rilb) to load balance the service-to-service communications in the Bank of Anthos application.

Designing for Failure: Chaos Engineering Best Practices
https://pulse.rajatgupta.work/designing-for-failure-chaos-engineering-best-practices-68503eb1b27b
If you are leading an engineering team today, your job isn't to prevent failure. It is to design systems that thrive in it. This is the discipline of Chaos Engineering. It is not just about breaking things in production; it is a scientific method for validating resilience.

Building a Centralized Multi Account AWS Monitoring Platform
https://medium.com/@varunarora1408/building-a-centralized-multi-account-aws-monitoring-platform-6b14b59ae9d4
I was previously part of an organization with 500+ devs with more than 25+ AWS accounts for each client which had to be managed by the DevOps team. The number of people in DevOps team was smaller than the accounts and all of them were mostly active with resources being allocated and deallocated frequently. We utilised many AWS services like EC2, S3, EKS, SageMaker, RDS, Redshift, Cloudfront, Route53, SSM etc

New Conversion from cgroup v1 CPU Shares to v2 CPU Weight
https://kubernetes.io/blog/2026/01/30/new-cgroup-v1-to-v2-cpu-conversion-formula
I'm excited to announce the implementation of an improved conversion formula from cgroup v1 CPU shares to cgroup v2 CPU weight. This enhancement addresses critical issues with CPU priority allocation for Kubernetes workloads when running on systems with cgroup v2.

Kubernetes Remote Code Execution Via Nodes/Proxy GET Permission
https://grahamhelton.com/blog/nodes-proxy-rce
In this post I'll describe how to execute code on every Pod in many Kubernetes clusters when using a service account with nodes/proxy GET permissions. This issue was initially reported through the Kubernetes security disclosure process and closed as working as intended.

Kubernetes v1.35: Extended Toleration Operators to Support Numeric Comparisons (Alpha)
https://kubernetes.io/blog/2026/01/05/kubernetes-v1-35-numeric-toleration-operators
In Kubernetes v1.35, we're introducing Extended Toleration Operators as an alpha feature. This enhancement adds Gt (Greater Than) and Lt (Less Than) operators to spec.tolerations, enabling threshold-based scheduling decisions that unlock new possibilities for SLA-based placement, cost optimization, and performance-aware workload distribution.

Migrating from Bitnami PostgreSQL to CloudNative-PG on Kubernetes
https://k8scockpit.tech/posts/cloudnative-pg
If you're running PostgreSQL on Kubernetes, chances are you've used Bitnami's popular Helm charts. They've been a go-to for many, but a significant change is on the horizon. As outlined in this GitHub issue, Bitnami is moving its production-ready charts and images to a commercial offering. For those of us who rely on and advocate for open-source solutions, this means it's time to find a robust alternative.

Case Study: Reducing Complexity By Migrating from K8S to ECS Fargate for NetworkLessons
https://dev.to/aws-builders/case-study-reducing-complexity-by-migrating-from-k8s-to-ecs-fargate-for-networklessons-3271
The Kubernetes story is one I hear often. Teams adopt K8s expecting operational simplicity, only to discover they've traded application complexity for infrastructure complexity. For a solo founder focused on content creation, maintaining a Kubernetes cluster was simply the wrong trade-off.

Database State Management in Kubernetes: Running SQL Server on AKS with GitOps
https://medium.com/@firaassboui/database-state-management-in-kubernetes-running-sql-server-on-aks-with-gitops-69286a87f8de
This article is about the patterns that actually work when you're managing real databases in Kubernetes, not hello-world demos: when your boss says "everything should be containerized" but your databases laugh in the face of ephemeral pods, and when GitOps meets a 200GB production database that absolutely cannot lose a single transaction.

Deploy LLM Models on OpenShift
https://medium.com/@ahmeddraz/deploy-llm-models-on-openshift-84ecb014f09a
Operators make life easier, but they are not always an option. In this post, I'll walk through a practical way to deploy large language models on OpenShift without relying on the OpenShift AI or NVIDIA operators. The approach uses llama.cpp as a lightweight runtime engine and runs a quantized GGUF model to enable efficient inference with minimal dependencies.

argocd-diff-preview
https://github.com/dag-andersen/argocd-diff-preview
Argo CD Diff Preview is a tool that renders the diff between two branches in a Git repository. It is designed to render manifests generated by Argo CD, providing a clear and concise view of the changes between two branches. It operates similarly to Atlantis for Terraform, creating a plan that outlines the proposed changes.
