This article explains why Kubernetes observability falls apart when metrics, logs and traces don't share context, and how consistent service identity, bounded label cardinality and OpenTelemetry pull them back together.

Modern cloud-native architecture is distributed by design — code repos, CI/CD pipelines, metrics, logs, traces, all spread across different tools and layers.

Greg Eppel explains how AWS DevOps Agent fits into this: it connects across the whole toolchain, stitches all those signals together, and simplifies what is typically an overwhelming amount of context into something an agent can reason about.

Frédéric Gaudet, Senior SRE @ BlaBlaCar, explains the technical process of contributing to Istio's warm-up configuration and the critical workflow for making API changes.

He breaks down Istio's dual-repository structure - the API repository containing protobuf definitions and CRDs, and the main code repository - and why understanding this architecture is essential for contributors.

CI updates Git while Argo CD updates the cluster.

At WSC Sports, Elad Cohen separates delivery responsibilities: CI patches a values file, and Argo CD reconciles the cluster. Self-healing keeps Git as the declared state.

- Why CI and CD need separate roles
- How ApplicationSets create shadow deployments
- How AppProjects restrict team access
- Why shared Helm charts reduce one-offs

Migrating to the Gateway API on Amazon EKS involves a fundamental shift: annotations no longer live on the load balancer resource.

Sai Vennam explains the new YAML-native CRDs, and why auditing your existing annotations is the first step of any migration.

Pumba lets you kill, pause, and stress containers while injecting network delays, packet loss, and corruption.

You can deploy it as a DaemonSet for cluster-wide chaos engineering.

"Deploying an AI agent or a model for inference is just another app."

Tsahi Duek argues companies don't adopt Kubernetes for AI from scratch — they already have the CI/CD pipelines, autoscaling, and observability in place. The same infrastructure that runs web services can shift to training jobs, then flip back to inference.

OpenDepot is a self-hosted, Kubernetes-native registry for your OpenTofu/Terraform modules and providers, so you control distribution and versions rather than relying on the public registry.

At Komodor, they spend 10% of development time building AI features and 80% on validation.

Itiel Shwartz explains the real cost of shipping AI for Kubernetes operations: LLM-as-a-judge, A-B testing, benchmarking — a full suite of evaluation before anything reaches production. The challenge isn't building AI capabilities. It's proving they actually work.

You need internal confidence first. Then you earn your users' confidence.

Kubernetes is not difficult because there are too many commands.

It is difficult because networking, scheduling, deployments, storage, autoscaling, and security interact in ways that are hard to see.

Our live Advanced Kubernetes course connects those pieces into one practical mental model.

The next online course runs on 10, 11, 17, and 18 September.

- Four days of live instruction
- 60% hands-on labs
- Small classes
- Lifetime access to the material and private Slack

This article argues that MCP servers for Kubernetes ship the accelerator without the brake, and walks through a two-tier design in which an agent can only propose a change, and a human approves the exact plan before it is applied.

AWS built SOCI and the fast-pull snapshotter to improve container image pull times — but they didn't keep it to themselves. Phil Estes explains why open source and upstream-first development were the only approaches that made sense.

The tools integrate directly with Containerd, work with any cluster (not just EKS), and improvements are flowing back into upstream core projects. You don't even need a custom snapshotter to benefit.

🚀 We just published The Technical Guide to Kubernetes Rightsizing in the Age of AI.

The guide follows the complete rightsizing process, from collecting metrics to applying changes safely in production.

- It explains how requests and limits affect scheduling and Linux resource controls.
- It examines how application runtimes change CPU and memory behavior.
- It also shows how KRR and VPA turn historical data into recommendations.

The book also examines where AI can help: collecting evidence, explaining recommendations, drafting policy, and carrying approved changes across systems without breaking prod.

Thank you to Gulcan and @danielepolencic for the research, experiments, writing, and illustrations behind this book.
