Managing DNS Records with AWS Route 53
In this live AWS environment you will learn how to create and manage DNS records inside of Route 53. You'll start by creating a simple application. It will serve as a test website from two EC2 instances, and will route traffic using an Application Load Balancer ELB. After this, you will create two records inside a Route 53 hosted zone that will configure the DNS settings for a custom domain and point it to your application.
Further, you'll look at how DNS works in this scenario (and in general) and how a command line utility like
dig can get more information about a domain. These skills will allow you to associate many kinds of AWS web applications with recognizable web domains such as yourcoolsite.com.
Here is a code snippet we'll need for this lab:
#!/bin/bash yum update -y yum install -y httpd cp /usr/share/httpd/noindex/index.html /var/www/html/index.html service httpd start
PLEASE ENSURE YOU USE THIS SNIPPET otherwise the ELB healthchecks will fail.
