Welcome back to Part 2 of our series on Extensible Virtual LAN (VXLAN)! In Part 1, we broke down the core concepts behind overlay networks. Now, it’s time to move from theory to execution. When a pod talks to a pod on another node, Cilium wraps the packet in
In Kubernetes environments, a very frustrating issue can happen: traffic between Pods on the same node works perfectly, but communication between Pods on different nodes hangs on large requests. Small packets like pings or basic TCP connections cross the nodes without any problem. However, larger transfers like TLS handshakes or
💡 kube-vip, MetalLB L2, Cilium L2 announcements, keepalived: these are different tools, but they all use the same trick. None of them give you load balancing. They give you a highly available VIP. (A VIP is a virtual IP address that can move between nodes.) That is not the same
