AWS CloudFormation YAML for Simple LoadBalancer

simple_load_balancer.yaml

---
AWSTemplateFormatVersion: '2010-09-09'
Description: 'AWS CloudFormation Sample Template ELBStickinessSample: Create a load
  balanced sample web site with ELB stickiness enabled. The AI is chosen based on
  the region in which the stack is run. This example creates 2 EC2 instances behind
  a load balancer with a simple health check. The ec2 instnces are untargeted and
  may be deployed in one or more availaiblity zones. The web site is available on
  port 80, however, the instances can be configured to listen on any port (8888 by
  default). **WARNING** This template creates one or more Amazon EC2 instances and
  an Application Load Balancer. You will be billed for the AWS resources used if you
  create a stack from this template.'
