Cloud Native Load Balancing From Scratch

on YouTube ↗33m

" summary

Builds a software load balancer with concrete tools: IPVS NAT/DR/tunnel modes, dummy interfaces and IPIP tunneling to reach backends across subnets, and GoBGP for advertising the VIP to upstream routers so multiple LB instances share traffic. Demo uses simple Bash scripts to run 1,000 curl requests, exercises connection persistence, and shows health checks removing failed backends with no visible disruption while scaling beyond L2 and eliminating the single-LB bottleneck.
