Depends on the Azure offering you want to use.

Azure SQL Database

You can get Geo-replication setup which is very straight forward and will give you a read-only secondary.

Azure Portal : Geo replication

Azure SQL Managed Instance : You can use regular transaction replication (under preview) or geo-replication. 

Azure Managed Instance
