Hi!
You could consider setting up an Azure SQL Sync Group which will allow you to synchronise your Azure SQL Database to another.
I have used it as a mechanism for syncing specific elements of the db schema to another Azure SQL Database owned by a separate customer business unit.
You can set the sync frequency between 5mins and 30 days which is suitable for your scenario of 15mins.
Here is a link which you may find useful for setting this up: https://learn.microsoft.com/en-us/azure/azure-sql/database/sql-data-sync-sql-server-configure
Hope this is along the correct lines of your query and that you find it useful.
Mark.
