Create a Load Balancer and two AutoScaling Group

This code creates an Application Load Balancer and Two Auto Scaling groups. It serves as basis to configure blue / green deployments.

Getting started

Initial tasks (to execute only once)

• Install CDK : https://docs.aws.amazon.com/en_pv/cdk/latest/guide/getting_started.html

npm install -g aws-cdk

• Bootstrap the CDK environment

cdk boostrap

For each redeployment

• Build the code

npm run build

• Deploy the code

cdk deploy

Cleanup

To cleanup the environment when you are done testing :

Application versions

The sample app is a sample static HTML page, taken from Boostrap's sample. Two versions of the same app are deployed. The blue version is deployed to the blue scaling group and the green version is deployed to the green group.
