Explanation
SAP GUI traffic uses protocols like DIAG and RFC, which operate at the transport/network layer (OSI layer 4). For this type of traffic, a Layer 4 load balancer is appropriate. The Azure Standard Load Balancer is recommended for SAP workloads on Azure to provide high availability and zone-redundant load balancing across Availability Zones. The Standard Load Balancer supports multiple front-end IPs and is suitable for cluster implementations such as SAP Central Services and application servers. SAP message server and logon groups handle load balancing of SAP GUI client connections internally, but when external load balancing is needed across VMs in multiple zones, Standard Load Balancer is the preferred Azure service.
