Amazon Route 53 is a DNS service designed to give businesses and developers an efficient way to connect users to Internet applications. 

What are the functions of Route 53?

The service provides three main functions:

Domain Registration 

Route 53 allows you to create public DNS records. You can also manage the IP addresses available for your domain names in the Internet’s DNS phone book. 

Domain Name System (DNS) service

Route 53 answers requests to translate domain names like into IP addresses like It responds to queries via a network of DNS servers. You can use Route 53 to transfer DNS records for an existing domain or create records for a new domain.

The service can effectively route Internet traffic to infrastructure that uses Amazon Web Services such as Amazon EC2 instances or S3 buckets. It can also be used to connect user requests to infrastructure that doesn't use Amazon Web Services. 

Health Checking 

Route 53 can monitor the health of your web servers, application, and other resources. It periodically sends requests to the endpoint to verify that it is available, reachable and functional. 

Benefits of Amazon Route 53

Route 53 provides a host of benefits to developers and businesses. These include:


The features of Route 53 help ensure a consistent ability to connect your users to your application. For instance, the DNS Failover feature can detect an outage of your website and redirect your users to other locations where your application is up and running. This increases redundancy to your website and helps maintain availability for your end users. 

Can be used with other Amazon Web Services

As mentioned previously, you can use Route 53 with other features of Amazon Web Services. You can map domain names to your Amazon S3 buckets, Amazon EC2 instances, and other Amazon Web Services resources. You can also map your zone apex to your Amazon S3 website, Amazon CloudFront distribution or Elastic Load Balancing instance. 


You can integrate Route 53 with AWS Identity and Access Management to grant permissions and credentials for any user within your AWS account. Additionally, you can specify who can access which elements of the Route 53 service. 


The service uses a network of DNS servers to connect users to areas with stable network conditions automatically. Consequently, the service provides low update latency for your DNS record management needs and low query latency for your users. 


Route 53 Traffic Flow allows you to route traffic based on latency, endpoint health, and geographic location. You can create traffic flow rules using the simple visual editor in the Route 53 API or Route 53 console.
This way, you get to manage how end users are connected to your application’s endpoints – whether distributed globally or in a single AWS region. 


With Route 53, you only pay for the resources you use. These include hosted zones, the number of queries the service answers for each of your domain and optional features such as health checks and traffic policies.
