On premise load balancers

On-premise Kubernetes load balancers provide LoadBalancer service type support for clusters running outside of cloud providers. While cloud providers automatically provision load balancers for LoadBalancer services, on-premise clusters need additional solutions to expose services externally. These load balancers typically work by assigning external IP addresses from a pool and using BGP, ARP, or Layer 2 protocols to advertise these IPs to the network infrastructure, making services accessible from outside the cluster.

Cilium LoadBalancer IP Address Management (LB IPAM)

Cilium's LB IPAM feature provides LoadBalancer service type support for on-premise clusters by automatically managing IP address allocation and assignment for load balancer services.

MetalLB

MetalLB is a load-balancer implementation for bare metal Kubernetes clusters, using standard routing protocols.

Kube-VIP

Kube-VIP provides Kubernetes Virtual IP and Load-Balancer for both control plane and Kubernetes services in bare-metal, edge, and virtualization environments.

loxilb.io

loxilb.io is a cloud-native load balancer for Kubernetes that provides high-performance layer 4 load balancing and can run in standalone mode or as a Kubernetes operator.

PureLB

PureLB is a load-balancer orchestrator for Kubernetes clusters that uses standard Linux networking and routing protocols, inspired by MetalLB.
