SQL Server Standard is undoubtedly one of the best selling editions due to its cost-effectiveness and feature sets. Its bigger sibling, the SQL Server Enterprise Edition is more than 3 times the cost. In most cases, only large companies can justify its cost benefits.

Optionally, you can add a Monitor server to monitor the entire deployment setup and check for errors. It also records history and status of backup/restore jobs. You can set up the monitoring server to raise alerts when jobs fail.

Note: For successful disaster recovery of your databases, you should also install a replica domain controller at the disaster recovery site(Azure).
You have the options to either have an Azure SQL Database (PAAS) or a SQL Server on Azure VM.
Note: You can only use Azure SQL DB as a Subscriber to the Primary On-Premises Publisher Server.
