AWS Construct Doc

This library includes constructs that represent all the resources available on AWS

Three levels of constructs

CFN Resources - L1

Also called Cfn (short for CloudFormation)

• periodically generated from AWS CloudFormation Resource Specification
  • named CfnXyz, Xyz is name of the resource. e.g., CfnBucket represents AWS::S3::Bucket resource
• must explicitly configure all resource properties

L2

• provide higher-level, intent-based API
• properties with defaults, also have bolierplate and glue logic
• e.g. s3.Bucket class

Patterns - L3

• designed to help you complete common tasks in AWS, often involving multiple kinds of resources

Initialization

Define a construct by instantiating the class, three parameters involved:

• Scope
• unique within this scope, as namespace for things defined inside this construct
• A set of properties or keywords arguments
