#8 About Kubernetes

January 16, 2026 · 01:14:59 · Krisztian Fischer & Toby Sears

Show Notes

In this episode, Toby and Krisztian are joined by Xavier Torres, a senior infrastructure and observability engineer, for a practical dive into Kubernetes. They cover what Kubernetes actually is, how pods, services, deployments and ingresses fit together, and what you genuinely need to run it in production. The conversation moves through observability tooling, GitOps with Argo CD, secrets management, service meshes, managed vs self-hosted Kubernetes, autoscaling, and whether Kubernetes is even the right tool for most companies.
