Explanation

Application Gateway is available under a Standard_v2 SKU. Web Application Firewall (WAF) is available under a WAF_v2 SKU. The v2 SKU offers performance enhancements and adds support for critical new features like autoscaling, zone redundancy, and support for static VIPs. Zone redundancy: An Application Gateway or WAF deployment can span multiple Availability Zones, removing the need to provision separate Application Gateway instances in each zone with a Traffic Manager. You can choose a single zone or multiple zones where Application Gateway instances are deployed, which makes it more resilient to zone failure. The backend pool for applications can be similarly distributed across availability zones. Zone redundancy is available only where Azure Zones are available. * Azure Load Balancer Standard For the load balancers of the failover clusters of SAP Central Services and the DBMS layer, you need to use the Standard SKU Azure Load Balancer. The Basic Load Balancer won't work across zones.
