MetalLB

Component Category

Network / load balancing

Component Description

MetalLB provides load-balancer capabilities for Kubernetes environments that do not have a native cloud load balancer. It is especially relevant for bare-metal and private infrastructure where public-cloud load balancer services are not available.

Why It Is Used

In BullSequana AI Runtime, MetalLB makes platform services reachable on bare-metal and private infrastructure. It is a key part of exposing ingress and service endpoints in self-managed environments and helps provide stable network addresses for platform entry points.
