What Is Amazon Route 53?
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. You can use Route 53 to perform three main functions:
- 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.
-
For an overview, see How Domain Registration Works.
-
For a procedure, see Registering a New Domain.
-
For a tutorial that takes you through registering a domain and creating a simple website in an Amazon S3 bucket, see Getting Started with Amazon Route 53.
-
- 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 (apex.example.com) in the address bar, Route 53 helps connect the browser with your website or web application.

-
- 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.

For procedures, see Creating Amazon Route 53 Health Checks and Configuring DNS Failover.
-
You can use any combination of these functions. For example, you can use Route 53 both to register your domain name and to route internet traffic for the domain, or you can use Route 53 to route internet traffic for a domain that you registered with another domain registrar. If you choose to use Route 53 for all three functions, perform the steps in this order:
-
Register your domain name.
-
Configure Route 53 to route internet traffic for your domain and subdomains.
-
Configure Route 53 to check the health of your resources.
