#### By default, Elastic Beanstalk creates all of your application's compute and networking
#### resources in the default VPC. Use this template to create a custom VPC with public subnets in
#### two availability zones.
####
#### This template creates the following resources-
####   - A VPC with the IP range 172.31.0.0/16
####   - 2 public subnets
####   - An Internet gateway, and route table to allow environment resources to connect to each
#### other and the Internet.
