We have REMOTE files in every directory that's a stack, and a Makefile that finds directories
with a REMOTE file to initialize their remote state appropriately.

// If a module needs a VPC output
resource "terraform_remote_state" "vpc" {
  backend = "s3"
  config {
    bucket = "terraform"
    
    // these vars propagate from the stack to every module
    key = "${var.region}/${var.environment}/vpc"
  }
}

// If a module needs to know about the NAT or jump hosts
resource "terraform_remote_state" "services" {
  backend = "s3"
  config {
    bucket = "terraform"
    
    // these vars propagate from the stack to every module
    key = "${var.region}/${var.environment}/services"
  }
}
