Determining the location of the secondary - Amazon Relational Database Service

Determining the location of the secondary

You can determine the location of the secondary replica by using the AWS Management Console. You need to know the location of the secondary if you are setting up your primary DB instance in a VPC.

Secondary AZ

You can also view the Availability Zone of the secondary using the AWS CLI command describe-db-instances or RDS API operation DescribeDBInstances. The output shows the secondary AZ where the standby mirror is located.
