conditional parameter See mapping.
configuration API Amazon CloudSearch (p. 110): The API call that you use to create, configure, and
manage search domains.
configuration template A series of key–value pairs that define parameters for various AWS products so
that AWS Elastic Beanstalk (p. 118) can provision them for an environment.
consistency model The method a service uses to achieve high availability. For example, it could
involve replicating data across multiple servers in a data center.
See Also eventual consistency.
console See AWS Management Console.
consolidated billing A feature of the AWS Organizations service for consolidating payment for
multiple AWS accounts. You create an organization that contains your AWS
accounts, and you use the master account of your organization to pay for all
member accounts. You can see a combined view of AWS costs that are incurred
by all accounts in your organization, and you can get detailed cost reports for
individual accounts.
container A Linux container that was created from a Docker image as part of a
task (p. 156).
container definition Specifies which Docker image (p. 129) to use for a container (p. 125), how
much CPU and memory the container is allocated, and more options. The
container definition is included as part of a task definition (p. 156).
container instance An EC2 instance (p. 129) that is running the Amazon Elastic Container Service
(Amazon ECS) (p. 111) agent and has been registered into a cluster (p. 124).
Amazon ECS task (p. 156)s are placed on active container instances.
container registry Stores, manages, and deploys Docker image (p. 129)s.
content delivery network
(CDN)
A web service that speeds up distribution of your static and dynamic web content
—such as .html, .css, .js, media files, and image files—to your users by using
a worldwide network of data centers. When a user requests your content, the
request is routed to the data center that provides the lowest latency (time delay).
If the content is already in the location with the lowest latency, the CDN delivers
it immediately. If not, the CDN retrieves it from an origin that you specify (for
example, a web server or an Amazon S3 bucket). With some CDNs, you can help
secure your content by configuring an HTTPS connection between users and data
centers, and between data centers and your origin. Amazon CloudFront is an
example of a CDN.
continuous delivery A software development practice in which code changes are automatically built,
tested, and prepared for a release to production.
See Also https://aws.amazon.com/devops/continuous-delivery/.
continuous integration A software development practice in which developers regularly merge code
changes into a central repository, after which automated builds and tests are run.
See Also https://aws.amazon.com/devops/continuous-integration/.
cooldown period Amount of time during which Auto Scaling (p. 115) does not allow the desired
size of the Auto Scaling group (p. 115) to be changed by any other notification
from an Amazon CloudWatch (p. 110) alarm (p. 109).
core node An EC2 instance (p. 129) that runs Hadoop (p. 134) map and reduce tasks and
stores data using the Hadoop Distributed File System (HDFS). Core nodes are
managed by the master node (p. 140), which assigns Hadoop tasks to nodes and
