Sometimes you want to retrieve EC2 insntances' region information.

You can query that information through instance metadata(169.254.169.254).

$ curl --silent http://169.254.169.254/latest/dynamic/instance-identity/document
{
  "privateIp" : "172.31.2.15",
  "instanceId" : "i-12341ee8",
  "billingProducts" : null,
 "instanceType" : "t2.small",
