Why does troubleshooting a Kubernetes overlay network take so long? This article breaks down how CNI works, the differences between Flannel VXLAN and Calico BGP, and the step-by-step process for isolating MTU mismatches that every K3s operator should know.
Why doesn't live migrating a VM (KubeVirt) between Kubernetes nodes break the connection? We break down Calico's IP persistence and BGP route convergence, and what it means for teams moving off VMware.
You're great at subnet design, so why does Pod-to-Pod communication in Kubernetes trip you up every time? We break down the fundamentals of Kubernetes networking—CNI, Service Mesh, and NetworkPolicy—by contrasting them with traditional network design.
Discover how Cilium uses eBPF to transform Kubernetes networking. Compare with traditional CNIs, explore L7 policies, and leverage Hubble for observability.
A thorough comparison of Docker network drivers — bridge, host, and overlay. Understand the architecture, performance, security trade-offs, and use-case selection criteria with practical examples.
Implement zero trust networking in Kubernetes with Network Policies. From Default Deny to Cilium and Calico advanced policies with real YAML examples.
