AI Infrastructure on K8s, Airbnb’s High Availability with Distributed Databases, Faster Pod Startup, Priority and Preemption, Cost vs Resilience

This newsletter is brought to you by StormForge by CloudBolt — ML-powered Kubernetes rightsizing that keeps clusters fast, efficient, and under control

Articles

1. AI Infrastructure on Kubernetes

   kube.today

   In this report, you will learn how Kubernetes teams actually scale AI workloads based on 917 survey responses, revealing the gap between vendor capabilities and real-world GPU utilization challenges.

2. Why Running Kubernetes Is Like Running an Airline (And What That Means for Optimization)

   www.cloudbolt.io

   See how airline-style “yield management” applies to Kubernetes.

   This article breaks down requests, limits, and autoscaling—and how ML-driven optimization keeps clusters efficient.

3. Achieving High Availability with distributed database on Kubernetes at Airbnb

   medium.com

   This case study shows how Airbnb runs a distributed SQL database across multiple Kubernetes clusters, coordinating node replacements, using custom operators, and isolating failures by availability zone.

4. Optimizing node and pod startup performance

   medium.com

   This case study shows how to improve Kubernetes node and pod startup times by caching images, enabling parallel pulls, and temporarily increasing EBS volume throughput.

5. How Kubernetes Pod Priority and Preemption Work

   chaitanyakharche.hashnode.dev

   This article explains how Kubernetes assigns priority to Pods with PriorityClasses, and how it can evict lower-priority Pods to make room for higher-priority ones when resources are tight.

6. Kubernetes pod scheduling: balancing cost and resilience

   cast.ai

   This article explores how scheduling policies can optimize resource usage while preserving fault tolerance.

   It covers strategies for using anti-affinity, spread constraints, and affinity weights to balance cost and resilience.

1. Hot-Patching Pods in Kubernetes 1.33: What Breaks, What Works, and How to Use It Safely

   www.cloudbolt.io

   Kubernetes 1.33 introduces in-place pod resizing, but it’s not as simple as it looks.

   Learn what actually works, what fails, and how StormForge by CloudBolt is making hot-patching safe and production-ready.

2. Deploying a .NET Weather Forecast App to AKS Using GitHub Actions and Argo CD

   medium.com

   This tutorial shows how to deploy a .NET weather forecast app to AKS using GitHub Actions to build/push the container and Argo CD to sync & deploy to the cluster.

3. kube-bench: The Posture Check That Time Forgot

   cloudsecburrito.com

   This tutorial walks you through running kube-bench for CIS compliance on Kubernetes, how to scan clusters using Jobs or CronJobs and understand which configurations pass or fail.

4. G-Cluster API + Talos + Proxmox = ❤️

   a-cup-of.coffee

   This guide shows how to provision fully automated Talos-based Kubernetes clusters on Proxmox using Cluster API, resolving key issues like bootstrap IP misconfig, cloud-init compatibility, missing providerID, and CCM integration for autoscaling.
