The internal load balancers are used to distribute traffic among healthy VMs. In this case, the load balancers are used for the SAP ASCS and ERS hosted servers. The load balancers have the same front end and back-end configuration, which means that they are both used to distribute traffic to the same set of VMs. The reason for this could be to provide redundancy and high availability for the SAP ASCS and ERS hosted servers. If one of the load balancers fails, the other one can take over and continue to distribute traffic to the VMs
