Example 1
===============================
Maps are a way to create variables that are lookup tables. An example will show this best. Let's extract our AMIs into a map and add support for the us-west-2 region as well:

variable "amis" {
  type = "map"
  default = {
    "us-east-1" = "ami-b374d5a5"
    "us-west-2" = "ami-4b32be2b"

# The goal: create a list of maps of subnet mappings so we don't have to statically hard-code them in aws_lb
# https://www.terraform.io/docs/providers/aws/r/lb.html#subnet_mapping
locals {
  # These represent dynamic data we fetch from somewhere, such as subnet IDs and EIPs from a VPC module
  subnet_ids = ["subnet-1", "subnet-2", "subnet-3"]
  eips       = ["eip-1", "eip-2", "eip-3"]
}

# Here's the hack! The null_resource has a map called triggers that we can set to arbitrary values. 
# We can also use count to create a list of null_resources. By accessing the triggers map inside of
