Valid Values: 0 - 15

Specifies whether the DB instance is publicly accessible.

When the DB instance is publicly accessible and you connect from outside of the DB instance's virtual private cloud (VPC), its domain name system (DNS) endpoint resolves to the public IP address. When you connect from within the same VPC as the DB instance, the endpoint resolves to the private IP address. Access to the DB instance is controlled by its security group settings.

When the DB instance isn't publicly accessible, it is an internal DB instance with a DNS name that resolves to a private IP address.

The default behavior when PubliclyAccessible is not specified depends on whether a DBSubnetGroup is specified.

If DBSubnetGroup isn't specified, PubliclyAccessible defaults to false for Aurora instances and true for non-Aurora instances.

If DBSubnetGroup is specified, PubliclyAccessible defaults to false unless the value of DBSubnetGroup is default, in which case PubliclyAccessible defaults to true.

If PubliclyAccessible is true and the VPC that the DBSubnetGroup is in doesn't have an internet gateway attached to it, Amazon RDS returns an error.

Specifes whether the DB instance is encrypted. By default, it isn't encrypted.

For RDS Custom DB instances, either enable this setting or leave it unset. Otherwise, Amazon RDS reports an error.

The storage throughput value, in mebibyte per second (MiBps), for the DB instance.

This setting applies only to the gp3 storage type.

This setting doesn't apply to Amazon Aurora or RDS Custom DB instances.

The storage type to associate with the DB instance.

If you specify io1, io2, or gp3, you must also include a value for the Iops parameter.

This setting doesn't apply to Amazon Aurora DB instances. Storage is managed by the DB cluster.

Valid Values: gp2 | gp3 | io1 | io2 | standard

Default: io1, if the Iops parameter is specified. Otherwise, gp3.
