This is a quick setup exercise for AWS CKD and EKS

Objectives:

1. Using AWS CDK (TypeScript) to deploy an EKS cluster in AWS
2. Deploy an application into the EKS cluster; this part doesn't have to be using CDK(even it's preferred), other method (kubectl, helm etc.) is also fine

Tasks:

1. Execute CDK code to spin up the EKS cluster
2. Deploy the application into EKS cluster
3. Destroy the configurations.
