If you choose to use Route 53 for all three functions, be sure to follow the order below:

1. Register domain names

Your website needs a name, such as example.com. Route 53 lets you register a name for your website or web application, known as a domain name.

2. Route internet traffic to the resources for your domain

When a user opens a web browser and enters your domain name (example.com) or subdomain name (acme.example.com) in the address bar, Route 53 helps connect the browser with your website or web application.

3. Check the health of your resources

Route 53 sends automated requests over the internet to a resource, such as a web server, to verify that it's reachable, available, and functional. You also can choose to receive notifications when a resource becomes unavailable and choose to route internet traffic away from unhealthy resources.
