aws-asg-cloudfront

This project demonstrates how to combine cloudfront, EC2, route53 and auto scaling groups to build a scalable http service with any load balancers.

NOTE: This project is a work in progress, I am shaving a few yaks along way.

Why?

The reason I built this example is that application load balancers introduce an unnecessary layer of complexity and cost in cases were your already using a CDN such as cloudfront in front of your application.

Setup

To deploy this solution you need to set some environment variables.

export HOSTED_ZONE_NAME=example.com
export HOSTED_ZONE_ID=ZZZZZZZZZZZZZZ
export DESIRED_CAPACITY=2
# Unique identifier used to build hostname
export INTERNAL_SERVICE_ID=aaaaaaaaaaaa
