Support for distributed network name (DNN) for SQL Server failover cluster instance (SQL FCI) on Azure IaaS with SQL Server 2019 CU2 and higher is now available.

By using DNN, you don’t need an Azure Load Balancer, and can simply use the same method you’ve been using on-premises for automated failover.
