All the infra code has been done manually, but added in .tf files as most of these activities can be done by terraform.
eg: creation of s3 buckets, creating IAM role, policy, trusted relationship, etc

There are some changes I had to make to the python data generator code to get it working.
1) category ["bws"] was removed from category frequency as it was not defined and resulted in script failure
2)changed delta from 3 months to 24 months as the story needed 2 years data
