publiclyAccessible

Indicates whether the DB instance is an internet-facing instance. If you specify true, AWS CloudFormation creates an instance with a publicly resolvable DNS name, which resolves to a public IP address. If you specify false, AWS CloudFormation creates an internal instance with a DNS name that resolves to a private IP address. The default behavior value depends on your VPC setup and the database subnet group. For more information, see the `PubliclyAccessible` parameter in the CreateDBInstance in the Amazon RDS API Reference.
