You can configure your high availability solution manually, or you can use templates in the Azure portal for automatic configuration. For an overview of all high availability options, see [High Availability and Disaster Recovery for SQL Server in Azure Virtual Machines](virtual-machines-windows-sql-high-availability-dr.md).
