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"
  }
