The amount of Provisioned IOPS (input/output operations per second) to be initially allocated for the DB instance.

Constraints: Must be a multiple between 3 and 10 of the storage amount for the DB instance. Must also be an integer multiple of 1000. For example, if the size of your DB instance is 500 GB, then your Iops value can be 2000, 3000, 4000, or 5000.

The KMS key identifier is the Amazon Resource Name (ARN) for the KMS encryption key. If you are creating a DB instance with the same AWS account that owns the KMS encryption key used to encrypt the new DB instance, then you can use the KMS key alias instead of the ARN for the KM encryption key.
