public IP address A pubic numerical address (for example, 192.0.2.44) that networked devices
use to communicate with one another using the Internet Protocol (IP). EC2
instance (p. 129)s 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.
public subnet A subnet (p. 155) whose instances can be reached from the internet.
PV virtualization Paravirtual virtualization. Allows guest VMs to run on host systems that do
not have special support extensions for full hardware and CPU virtualization.
Because PV guests run a modified operating system that does not use hardware
emulation, they cannot provide hardware-related features such as enhanced
networking or GPU support.
See Also HVM virtualization.

quartile binning
transformation
Amazon Machine Learning: A process that takes two inputs, a numerical variable
and a parameter called a bin number, and outputs a categorical variable. Quartile
binning transformations discover non-linearity in a variable's distribution by
enabling the machine learning model to learn separate importance values for
parts of the numeric variable’s distribution.
Query A type of web service that generally uses only the GET or POST HTTP method and
a query string with parameters in the URL.
See Also REST.
query string authentication An AWS feature that lets you place the authentication information in the HTTP
request query string instead of in the Authorization header, which enables
URL-based access to objects in a bucket (p. 122).
queue A sequence of messages or jobs that are held in temporary storage awaiting
transmission or processing.
queue URL A web address that uniquely identifies a queue.
quota Amazon RDS (p. 113): The maximum number of DB instance (p. 127)s and
available storage you can use.
Amazon ElastiCache (p. 111): The maximum number of the following items:
• The number of cache clusters for each AWS account (p. 109)
• The number of cache nodes per cache cluster
• The total number of cache nodes per AWS account across all cache clusters
created by that AWS account
