The Amazon KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the KMS key. To use a KMS key in a different Amazon Web Services account, specify the key ARN or alias ARN.

This setting doesn't apply to Amazon Aurora DB instances. The Amazon KMS key identifier is managed by the DB cluster. For more information, see CreateDBCluster.

If StorageEncrypted is enabled, and you do not specify a value for the KmsKeyId parameter, then Amazon RDS uses your default KMS key. There is a default KMS key for your Amazon Web Services account. Your Amazon Web Services account has a different default KMS key for each Amazon Web Services Region.

For Amazon RDS Custom, a KMS key is required for DB instances. For most RDS engines, if you leave this parameter empty while enabling StorageEncrypted, the engine uses the default KMS key. However, RDS Custom doesn't use the default key when this parameter is empty. You must explicitly specify a key.

Type: String

Required: No

LicenseModel

The license model information for this DB instance.

Note

License models for RDS for Db2 require additional configuration. The Bring Your Own License (BYOL) model requires a custom parameter group and an Amazon License Manager self-managed license.

PreferredBackupWindow

The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter. The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Web Services Region. For more information, see Backup window in the Amazon RDS User Guide.

This setting doesn't apply to Amazon Aurora DB instances. The daily time range for creating automated backups is managed by the DB cluster.

  • Must be in Universal Coordinated Time (UTC).

  • Must not conflict with the preferred maintenance window.

  • Must be at least 30 minutes.

Type: String

Required: No

PreferredMaintenanceWindow

The time range each week during which system maintenance can occur. For more information, see Amazon RDS Maintenance Window in the Amazon RDS User Guide.

The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Web Services Region, occurring on a random day of the week.

Constraints:

  • Must be in the format ddd:hh24:mi-ddd:hh24:mi.

  • The day values must be mon | tue | wed | thu | fri | sat | sun.

  • Must be in Universal Coordinated Time (UTC).

ProcessorFeatures.ProcessorFeature.N

The number of CPU cores and the number of threads per core for the DB instance class of the DB instance.

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

Type: Array of ProcessorFeature objects

Required: No

PromotionTier

The order of priority in which an Aurora Replica is promoted to the primary instance after a failure of the existing primary instance. For more information, see Fault Tolerance for an Aurora DB Cluster in the Amazon Aurora User Guide.

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

Default: 1

Valid Values: 0 - 15

Type: Integer

Required: No

PubliclyAccessible

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 ultimately controlled by the security group it uses. That public access is not permitted if the security group assigned to the DB instance doesn't permit it.

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.

Default: The default behavior varies depending on whether DBSubnetGroupName is specified.

If DBSubnetGroupName isn't specified, and PubliclyAccessible isn't specified, the following applies:

  • If the default VPC in the target Region doesn’t have an internet gateway attached to it, the DB instance is private.

  • If the default VPC in the target Region has an internet gateway attached to it, the DB instance is public.

If DBSubnetGroupName is specified, and PubliclyAccessible isn't specified, the following applies:

  • If the subnets are part of a VPC that doesn’t have an internet gateway attached to it, the DB instance is private.

  • If the subnets are part of a VPC that has an internet gateway attached to it, the DB instance is public.

Type: Boolean

Required: No

StorageEncrypted

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.

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

Type: Boolean

Required: No

StorageThroughput

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.

Type: Integer

Required: No

StorageType

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.

Type: String

Required: No

Tags.Tag.N

Tags to assign to the DB instance.

Type: Array of Tag objects

Required: No

TdeCredentialArn

The ARN from the key store with which to associate the instance for TDE encryption.

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

Type: String

Required: No

TdeCredentialPassword

The password for the given ARN from the key store in order to access the device.

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

Type: String

Type: String

Required: No

VpcSecurityGroupIds.VpcSecurityGroupId.N

A list of Amazon EC2 VPC security groups to associate with this DB instance.

This setting doesn't apply to Amazon Aurora DB instances. The associated list of EC2 VPC security groups is managed by the DB cluster.

Default: The default EC2 VPC security group for the DB subnet group's VPC.

Type: Array of strings

Required: No
