Question: What is the reason for building the an S3 bucket for each region

[nandac]

Dear Folks,

I have a question regarding the following Terraform resources:

resource "aws_s3_bucket" "AHA-S3Bucket-PrimaryRegion" {
    count      = "${var.ExcludeAccountIDs != "" ? 1 : 0}"
    bucket     = "aha-bucket-${var.aha_primary_region}-${random_string.resource_code.result}"
    tags = {
      Name        = "aha-bucket"
    }
}

resource "aws_s3_bucket" "AHA-S3Bucket-SecondaryRegion" {
    count      = "${var.aha_secondary_region != "" && var.ExcludeAccountIDs != "" ? 1 : 0}"
    provider   = aws.secondary_region
    bucket     = "aha-bucket-${var.aha_secondary_region}-${random_string.resource_code.result}"
    tags = {
      Name        = "aha-bucket"
    }
}

I was not able to figure out what they are used for.

I think they are used for a CSV file holding data about excluded accounts if so I do not see a reason to create these buckets if I were just to pass the excluded accounts as a list in Terraform that is interpreted in python as a string and parsed.

If someone could tell me what these buckets are used for that would be great.

Many thanks.
