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 in any combination: domain registration, DNS routing, and health checking.
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.
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.
- 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.
For an overview, see How internet traffic is routed to your website or web application.
For procedures, see Configuring Amazon Route 53 as your DNS service.
For a procedure on how to route email to Amazon WorkMail, see Routing traffic to Amazon WorkMail.
- 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.
For an overview, see How Amazon Route 53 checks the health of your resources.
For procedures, see Creating Amazon Route 53 health checks and configuring DNS failover.
Other Route 53 features
In addition to being a Domain Name System (DNS) web service, Route 53 offers the following features:
- Route 53 Resolver
Get recursive DNS for your Amazon VPCs in AWS Regions, VPCs in AWS Outposts racks, or any other on-premises networks. Create conditional forwarding rules and Route 53 endpoints to resolve custom names mastered in Route 53 private hosted zones or in your on-premises DNS servers.
For more information , see What is Amazon Route 53 Resolver?.
- Amazon Route 53 Resolver on Outposts endpoints
Connect Route 53 Resolver on Outpost racks with DNS servers in your on-premises data centers through Route 53 Resolver endpoints. This enables resolution of DNS queries between the Outposts racks and your other on-premises resources.
For more information , see What is Amazon Route 53 on Outposts?.
- Route 53 Resolver DNS Firewall
Protect your recursive DNS queries within the Route 53 Resolver. Create domain lists and build firewall rules that filter outbound DNS traffic against these rules.
For more information , see Route 53 Resolver DNS Firewall.
- Traffic flow
Easy-to-use and cost-effective global traffic management: route end users to the best endpoint for your application based on geoproximity, latency, health, and other considerations.
For more information , see Using traffic flow to route DNS traffic.
- Amazon Route 53 Profiles
With Route 53 Profiles, you can apply and manage DNS-related Route 53 configurations across many VPCs and in different AWS account.
For more information , see Amazon Route 53 Profiles.
