KubeLB is a project by Kubermatic, it is a Kubernetes native tool, responsible for centrally managing load balancers for Kubernetes clusters across multi-cloud and on-premise environments.
Kubernetes does not offer any implementation for load balancers and in turn relies on the in-tree or out-of-tree cloud provider implementations to take care of provisioning and managing load balancers. This means that if you are not running on a supported cloud provider, your services of type LoadBalancer will never be allotted a load balancer IP address. This is an obstacle for bare-metal Kubernetes environments.
There are solutions available like MetalLB, Cilium, etc. that solve this issue. However, these solutions are focused on a single cluster where you have to deploy the application in the same cluster where you want the load balancers. This is not ideal for multi-cluster environments since you have to configure load balancing for each cluster separately, which makes IP address management not trivial.
KubeLB solves this problem by providing a centralized load balancer management solution for Kubernetes clusters across multi-cloud and on-premise environments.
