primary key One or two attributes that uniquely identify each item in a Amazon
DynamoDB (p. 110) table, so that no two items can have the same key.

principal The user (p. 157), service, or account (p. 109) that receives permissions that

permission to do B to C."
private content When using Amazon CloudFront (p. 110) to serve content with an Amazon
S3 (p. 113) bucket (p. 122) as the origin, a method of controlling access to
your content by requiring users to use signed URLs. Signed URLs can restrict
user access based on the current date and time and/or the IP addresses that the
requests originate from.
private IP address A private numerical address (for example, 192.0.2.44) that networked devices
use to communicate with one another using the Internet Protocol (IP). All EC2
instance (p. 129)ss are assigned two IP addresses at launch, which are directly
mapped to each other through Network Address Translation (NAT (p. 141)): a
private address (following RFC 1918) and a public address. Exception: Instances
launched in Amazon VPC (p. 114) are assigned only a private IP address.
private subnet A VPC (p. 159) subnet (p. 155) whose instances cannot be reached from the
internet.
product code An identifier provided by AWS when you submit a product to AWS
Marketplace (p. 119).

and output values in an AWS CloudFormation (p. 116) template.
Provisioned IOPS A storage option designed to deliver fast, predictable, and consistent I/O
performance. When you specify an IOPS rate while creating a DB instance,
Amazon RDS (p. 113) provisions that IOPS rate for the lifetime of the DB
instance.
pseudo parameter A predefined setting, such as AWS:StackName that can be used in AWS
CloudFormation (p. 116) templates without having to declare them. You can use
pseudo parameters anywhere you can use a regular parameter.
public AMI An Amazon Machine Image (AMI) (p. 112) that all AWS account (p. 109)s have
permission to launch.
public data set A large collection of public information that can be seamlessly integrated into
AWS cloud-based applications. Amazon stores public data sets at no charge to the
community and, like all AWS services, users pay only for the compute and storage
they use for their own applications. These data sets currently include data from
the Human Genome Project, the U.S. Census, Wikipedia, and other sources.
