How can we create Multi-AZ AWS RDS for Custom SQL Server 2019 without paying SQL Server license cost on passive, secondary, failover instance?

Answer

There are 2 ways to license SQL Server on RDS Custom for SQL Server: License Included, or Bring-Your-Own-Media.

For Bring-Your-Own-Media, you provide your own installation media and license, which you can use in accordance to Microsoft terms. The [License Mobility Page](https://aws.amazon.com/windows/resources/licensemobility/) offers detailed information on the process. Because RDS Custom's Multi-AZ secondary instance is a passive node, it qualifies as a passive, secondary failover instance.

Documentation on the Multi-AZ deployment model for RDS Custom for SQL Server [can be found here](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/custom-sqlserver-multiaz.html#custom-sqlserver-multiaz.prerequisites).
