Welcome to your CDK TypeScript project for Multiple Environment deployment

AWS CDK Construct for deployment of AWS Services

· AWS Profile setup 
· AWS Role with required permission based on the resources planning to deploy

This CDK project covers below Production use cases

· AWS Services deployment across environment (Development /Production etc).
· Ability to define variable based on environment
· Output value of each deployed resource

Coding Standards followed

Command  cdk bootstrap aws://ACCOUNT-NUMBER-1/REGION-1

· Update environment specific variables in cdk.json file

· To Synthesize CDK app and generate CloudFormation template
Command -  cdk synth
