Who Owns Your Kubernetes Platform?, with Daniele Polencic and Molly Sheets

An application release can flood a shared Kubernetes cluster with logs, even though another team owns the logging infrastructure. Who has enough context to find the cause—and who owns the fix? Molly Sheets joins Daniele Polencic and Bart Farrell to examine how tenancy decisions affect coordination, maintenance, and staffing costs. She connects ownership to business goals and explains why faster AI-assisted changes still need controlled releases. In this episode: The cost of one central team supporting multiple tenancy models Why AI Ops needs context from application and platform teams Network boundaries for AI-generated workloads Maintenance as quality, with canary and cell-based releases Sponsor This episode is sponsored by LearnKube. When a release breaks production, can your developers and platform engineers troubleshoot it together?

Building Platforms for AI Agents, with Mauricio (Salaboy) Salatino

Non-deterministic agents pose specific challenges for platform teams in observability, state management, governance, and trust. Mauricio (Salaboy) Salatino explains why agentic applications behave like distributed multi-agent systems. His test assigned agents to take an order, cook the pizza, deliver it, and charge the customer. One order crossed 15 containers and produced 200 traces. In this interview: Why agent frameworks can recreate monolith scaling and resource contention How OpenTelemetry data can measure agent behavior and trust over time Why narrowly scoped agents are safer than agents that follow long sequences How the platform can become the learning layer that feeds better context back to LLMs Sponsor Kubernetes moves too fast to track everything.

Kubernetes Can Run Your Database. Your Team Can't., with Kat Cosgrove

KubeSelect is a new show that tests one bold Kubernetes hypothesis with one expert. Hosts Salman Iqbal and Bart Farrell examine the evidence and ask whether the claim holds up. In episode two, Kat Cosgrove tackles a long-running question: should teams run databases on Kubernetes? StatefulSets, persistent volumes, CSI, and database operators changed the technical answer, but they did not remove the operational risk. In this episode: How Kubernetes storage has matured and why old assumptions persist Where Kubernetes responsibility ends, and database responsibility begins Why operators do not replace database experts When managed database services remain the better choice Sponsor Kubernetes moves too fast to track everything.

Observability Won't Save You, with Henrik Rexed

Kube Select takes one bold Kubernetes hypothesis and tests it with an expert. In the first episode, Salman Iqbal and Bart Farrell ask whether most organizations have an observability problem or a decision-making problem. Henrik Rexed , Senior Staff Engineer at Dynatrace, challenges the original claim. Teams can collect metrics, logs, and traces, but that telemetry needs system relationships, ownership, and deployment history to support a confident decision. In this episode: Why telemetry without context slows incident response How SLOs, ownership, and deployment events guide troubleshooting When more metrics increase cost without improving decisions How AI agents can investigate incidents without replacing human judgment Sponsor Kubernetes moves too fast to track everything.

Why Kubernetes Needs to Learn GPUs, with Saiyam Pathak

Kube Signals starts where the keynote ends: with the trends that platform teams will have to operationalize next. In this special episode, Brian Teller speaks with Saiyam Pathak about his KubeCon India keynote and the shift from developer platforms to AI factories. They examine what GPU scarcity, shared accelerators, and AI workloads mean after the conference slides meet real infrastructure. In this interview: Why GPU infrastructure is becoming a platform-engineering concern How DRA, HAMI, MIG, and MPS change GPU allocation and utilization Where isolation, scheduling, and observability become harder for AI platforms Which cloud-native AI trends and projects platform engineers need to watch Sponsor This episode is sponsored by LearnKube.

GitOps at Enterprise Scale, with Elad Cohen

At enterprise scale, a deployment pipeline that runs Helm upgrades directly against Kubernetes hides drift, mixes configuration with CI logic, and makes the last pipeline run the source of truth. Elad Cohen explains how WSC Sports moved from Azure DevOps to GitHub Actions and redesigned delivery around Git and Argo CD. The resulting platform separates builds from deployments, keeps service configuration in values files, and continuously reconciles clusters. In this interview: Why CI should change Git instead of the cluster How ApplicationSets create main and shadow deployments from one values file How AppProjects scope permissions and route alerts by team Why reusable Helm contracts make customization compound across services Sponsor This episode is sponsored by LearnKube.

Automating Pod Disruption Budgets with Kyverno, with Ahmad Asmar

Karpenter can reduce Kubernetes infrastructure costs, but aggressive node consolidation can also expose workloads that lack disruption safeguards. Ahmad Asmar explains how Zencity uses Kyverno to automatically generate Pod Disruption Budgets , while accounting for existing PDBs, percentage-based availability targets, single-replica workloads, and environment-specific policies. In this interview: How Karpenter consolidation changes the availability risks of cluster operations Why Kyverno's generated policies can provide safer defaults than manual enforcement How to handle duplicate PDBs, scaling workloads, and single-replica edge cases How aggregated ClusterRoles keep custom permissions separate from Helm-managed resources Sponsor This episode is sponsored by LearnKube.

From KIAM to EKS Pod Identities, with Fabián Sellés Rosa

An unmaintained identity component can remain invisible until a routine Kubernetes upgrade turns it into an incident. Fabián Sellés Rosa , Platform Engineer and Runtime Tech Lead at Adevinta, explains how his team moved from KIAM to EKS Pod Identities without discarding the security boundaries and application interface that their internal platform depended on. In this interview: Why KIAM became urgent to replace after years of stable operation How Crossplane, a custom controller, and KRO with ACK compared against the team's criteria Why managed EKS Capabilities reduced toil but introduced observability and rollout trade-offs How Kyverno preserved namespace-level authorization for IAM roles Sponsor This episode is sponsored by LearnKube.

1 Million Tokens Per Second on Kubernetes, with Federico Iezzi

GPU inference throughput depends on more than accelerator generation or count. Memory bandwidth, model parallelism, cache configuration, and the load generator itself all influence measured throughput. Federico Iezzi , Customer Engineer at Google Cloud, explains how his team achieved 1 million output tokens per second using Qwen 3.5 27B, vLLM, GKE Autopilot, and NVIDIA B200 GPUs. The discussion covers: Why memory bandwidth limits decode performance How Federico chose between tensor and data parallelism What changed after enabling multi-token prediction and reducing the KV cache footprint with FP8 quantization.

The Hidden Cost of Slow Autoscaling, with John Ford

Forced platform migrations are usually treated as something to survive. At Scout24, a mandatory OS migration became an opportunity to rethink Kubernetes autoscaling, node provisioning, and infrastructure efficiency. John Ford explains how Scout24 moved its EKS-based Infinity platform from a polling autoscaler and over-provisioned capacity to Karpenter and Bottlerocket . The result was faster node startup, a safer migration path, and about a 30% infrastructure reduction without major downtime. In this interview: Why two-minute node provisioning forced a 25% capacity buffer How Karpenter made the Bottlerocket migration safer What broke around EC2 metadata, AWS SDKs, and cgroups How the new foundation enables Spot, ARM, and GPU workloads Sponsor This episode is sponsored by LearnKube — get started on your Kubernetes journey through comprehensive online, in-person or remote training.
