labeled data
In machine learning, data for which you already know the target or “correct” answer.
launch configuration
A set of descriptive parameters used to create new EC2 instances in an Auto Scaling activity.
A template that an Auto Scaling group uses to launch new EC2 instances. The launch configuration contains information such as the Amazon Machine Image (AMI) ID, the instance type, key pairs, security groups, and block device mappings, among other configuration settings.
launch permission
An Amazon Machine Image (AMI) attribute that allows users to launch an AMI.
lifecycle
The lifecycle state of the EC2 instance contained in an Auto Scaling group. EC2 instances progress through several states over their lifespan; these include Pending, InService, Terminating and Terminated.
lifecycle action
An action that can be paused by Auto Scaling, such as launching or terminating an EC2 instance.
lifecycle hook
Enables you to pause Auto Scaling after it launches or terminates an EC2 instance so that you can perform a custom action while the instance is not in service.
link to VPC
The process of linking (or attaching) an EC2-Classic instance to a ClassicLink-enabled VPC.
See Also ClassicLink.
See Also unlink from VPC.
load balancer
A DNS name combined with a set of ports, which together provide a destination for all requests intended for your application. A load balancer can distribute traffic to multiple application instances across every Availability Zone within a region. Load balancers can span multiple Availability Zones within an Amazon EC2 region, but they cannot span multiple regions.
local secondary index
An index that has the same partition key as the table, but a different sort key. A local secondary index is local in the sense that every partition of a local secondary index is scoped to a table partition that has the same partition key value.
See Also local secondary index.
logical name
A case-sensitive unique string within an AWS CloudFormation template that identifies a resource, mapping, parameter, or output. In an AWS CloudFormation template, each parameter, resource, property, mapping, and output must be declared with a unique logical name. You use the logical name when dereferencing these items using the Ref function.
