As frontend IPAM solution and IP announcement, KubeLB could use on-premise non-multi-tenant LB implementations like Cilium or MetalLB in Layer 2 ARP or BGP mode. (Also commercial Kubernetes conform implementation like [F5 Big IP](https://clouddocs.f5.com/products/connectors/k8s-bigip-ctlr/v1.0/#) would work). KubeLB will add the multi-tenant plus central DNS, Certificate and Ingress management. KubeLB deliver for each Kubernetes Cluster one tenant separated authentication token, what get used via the so called [KubeLB CCM](https://docs.kubermatic.com/kubelb/v1.1/installation/tenant-cluster/), what automatically get configured for KKP clusters. The KubeLB CCM is then handling service and node announcements. For Setups where multi-tenant automated LB is not required, direct [MetalLB](https://metallb.universe.tf/) or [Cilium](https://docs.cilium.io/) setups could be used as well. For the best performance and stability of the platform, we recommend to talk with our consultants to advise you what is the best fit for your environment.
