This tutorial shows how to chain KEDA cron scaling with Karpenter so non-prod EKS clusters drop to zero nodes at night and on weekends, cutting the compute bill by 65 to 85%.More: https://ku.bz/J18t6k5N5

This case study traces a 503 at the ingress back to a broken CNI overlay between nodes, even though every pod and endpoint looked healthy, and fixes it with topology spread constraints.More: https://ku.bz/M-PjSd6Tl

Frédéric Gaudet, Senior SRE @ BlaBlaCar, explains his testing approach for validating Istio's pod warm-up feature before production deployment.He reveals a critical insight about the interaction between pod warm-up and Horizontal Pod Autoscaler (HPA). When a new pod warms up and receives reduced traffic, that traffic gets redistributed to existing pods, potentially triggering CPU spikes. However, he discovered that keeping warm-up duration under the HPA trigger time (2 minutes warm-up vs 5 minutes HPA trigger) prevents instability.Watch the full episode: https://ku.bz/grxcypt9jKube Architect

We just published Kubernetes Architecture in Financial Services, a free technical book about platform design and operations.Drawing on public engineering talks and case studies from seven banks, it examines:- Tenant boundaries beyond namespaces. - Shared delivery controls and application ownership. - Policy maintenance, exceptions, adoption, and reporting. - Cross-cluster identity, reliability, external dependencies, and cluster replacement.Each chapter starts with a real platform problem, compares different boundaries, and examines the operational cost of each option.Thank you to Buoyant, Sysdig, and Nirmata for supporting the book and its research.Download it for free: https://learnkube.com/kubernetes-architecture-financial-services

This case study shows what happened when a team swapped etcd for Google Cloud Spanner, using commit timestamps instead of a single revision counter, so writes no longer queue behind each other.More: https://ku.bz/gPW89HJPw

Managed Kubernetes makes cluster operations easier, but service gaps still show up in real environments.Referencing a point raised in the Grzegorz Głąb episode, Christopher Tineo describes one of the practical tradeoffs he has seen in Google Cloud: some services are not equally available across regulated environments, which means teams still need to look beyond managed offerings and evaluate open-source options.The lesson is that managed services reduce toil, but they do not remove architectural constraints.Watch the full interview: https://ku.bz/5f9sFC6CGThis interview is a reaction to Grzegorz Głąb's episode https://ku.bz/yg_fkP0LN.Kube Architect

Danyl Novhorodov, Software Engineer & Architect @ Eneco, explains that Kubernetes can be clean, resilient, and efficient, but only when managed by teams with deep platform understanding, clear infrastructure-application boundaries, and strong operational discipline around security and CI/CD.Without these foundations, he compares it to "giving a Formula One car to someone who just got their driving license" - the tool isn't broken, it's simply misapplied.Watch the full episode: https://ku.bz/BYhFw8RwWKube Architect

A pizza order became a 15-container, 200-trace system.In Kube Signals episode two, Brian Teller and Mauricio (Salaboy) Salatino examine observability, state management, governance, and trust for non-deterministic agents.They discuss:- Why multi-agent runtimes can recreate monolith scaling - How OpenTelemetry exposes prompts, completions, and decisions - Why execution history turns agent trust into measurable evidenceWatch: https://ku.bz/TlVjXdnb6Kubernetes moves too fast to track everything.
