| Best software load balancers for bare-metal Kubernetes clusters | #2 / 8 | #1 / 8 |
Why the models rank Cilium — on best software load balancers for bare-metal kubernetes clusters
“eBPF datapath doubles as kube-proxy replacement, so a single CNI both routes and advertises LoadBalancer IPs — BGP peering for routed environments, L2/ARP announcements for flat networks, plus LB-IPAM pools, DSR, Maglev consistent hashing, and observability via Hubble; the strongest choice when you're already committing to Cilium as the CNI and want L4 service LB without a second component”
Why the models rank MetalLB — on best software load balancers for bare-metal kubernetes clusters
“Best general-purpose choice: a mature, CNI-agnostic LoadBalancer implementation with simple ARP/NDP mode and production BGP/ECMP through FRR-K8s, including BFD, dual-stack, IPv6, and routing-policy controls.”
