@vgodwinamz @rameshv29 Thankyou so much for the PR, here is the feedback on changes to approach:

1. We want to two terraform scripts to work separately to create separate DBs for windows and aurora. Basically in modernization journey first Sql server based RDS cluster is created and then people move to aurora, so we need separate templates
2. We need the state and backend config to be saved in S3 bucket like this example.
3. Finally we also need a CodeBuild project like this so which can invoke the terraform script.
