+Credentials for Informatica User (for test and prod instances) are stored in parameter store (in regions `us-east-1` and

### Credentials in Terraform
* It's recommended to define all variables values in a `*.tfvars` file and pass that to terraform using `-var-file` argument.
- This will avoid having Informatica credentials in bash history.
