Route 53 is Amazon’s managed Domain Name System (DNS). You can use it to register (or transfer) domain names, and manage how traffic is routed to public and private resources.
In this hands-on tutorial, I’ll explain in simple terms how it all works. We’ll take a look at common DNS record types, including A Record, CNAME Record, and the Alias that allows you to redirect traffic to AWS resources (we’ll point to an Elastic Beanstalk application).
