@krishnachaytanya: One server doing all the work while the others sit idle. A load balancer fixes it: it spreads requests across servers (round-robin) so each stays near 33% and nothing drops, instead of one box hitting 100% and throwing 503s. One door to many servers. Round-robin, least-connections, or IP-hash: which do you run? Save this one. #trending #vibecoding #systemdesign #ai #softwarearchitecture
