Amazon Route 53 is a highly scalable Domain Name System (DNS) web service that converts word-based website addresses like\u00a0www.example.com<\/a><\/strong>\u00a0into IP addresses like 11.22.33.44.<\/p>\n

Amazon Web Services operates worldwide DNS servers at 50+ edge locations. AWS domain queries are automatically routed to the nearest DNS server that will provide the quickest response time, which will help to lower update latency for DNS record management. For example, if you want to remap a domain to a different IP in GoDaddy, it takes anywhere from 30 minutes to 24 hours to propagate the change around the world. But in Route 53 the change will take effect within minutes.<\/p>\n

AWS Route 53 integrates with other AWS features. You can use it to map domain names to your Amazon EC2 instances, Amazon S3 buckets, Amazon CloudFront distributions and other AWS resources.<\/p>\n

“R53” offers Weighted Round Robin (WRR), also known as DNS load balancing, which allows you to assign weights to DNS records in order to specify which portions of your traffic will be routed to various endpoints. It allows you to load balance your application across multiple regions in order to provide low latency to end users.<\/p>\n

It lets you configure DNS failover in active-active, active-passive and mixed configurations to improve your application\u2019s availability. You can configure this service\u00a0to check the health of your resources so that you can respond to DNS queries using only healthy resources .<\/p>\n

For example, if your DR environment is running in another region, you can configure DNS to failover to the DR environment when something goes wrong with live servers.<\/p>\n

1. Create a Hosted Zone<\/strong><\/h2>\n

Log in to the Amazon console and navigate to Services->Route 53.<\/p>\n

In the AWS console, click\u00a0Create Hosted Zone<\/strong>\u00a0tab. Specify a domain name and a comment for your domain.<\/p>\n

 <\/p>\n

\"amazon<\/center><\/p>\n

Click the\u00a0Create Hosted Zone<\/strong>\u00a0button at the bottom of the screen. This will create the Hosted Zone for your domain, as well as NS and\u00a0SOA<\/a>\u00a0records.<\/p>\n

Select the Hosted Zone that you just created and click\u00a0Go to Records Sets<\/strong>.<\/p>\n

 <\/p>\n

\"amazon<\/center><\/p>\n

In\u00a0Record Sets<\/strong>, you will see the NS and SOA records.<\/p>\n

 <\/p>\n

\"Route53<\/center><\/p>\n

2. Create an A Record (IP Address).<\/strong><\/h2>\n

Map the domain to an IP address.<\/p>\n

Click\u00a0Create Record Set<\/strong>.<\/p>\n

In the right window specify the\u00a0Name<\/strong>\u00a0field as\u00a0www<\/strong>. Route 53 will automatically append \u201cexample.com\u201d.<\/p>\n

If you want to map the\u00a0naked domain<\/strong>, e.g.,example.com, leave the\u00a0Name<\/strong>\u00a0field blank.<\/p>\n

Select\u00a0A-IPV4<\/strong>\u00a0address from the\u00a0Type<\/strong>\u00a0dropdown menu.<\/p>\n

Keep\u00a0Alias<\/strong>\u00a0at the\u00a0No<\/strong>\u00a0default value.<\/p>\n

By default,\u00a0TTL<\/strong>\u00a0is 300 seconds, but you can change it to meet your needs. A 1-hour TTL is good for\u00a0A records<\/strong>.<\/p>\n

Specify your IP address in the\u00a0Value box<\/strong>.<\/p>\n

Leave the\u00a0Routing Policy<\/strong>\u00a0at the\u00a0Simple<\/strong>\u00a0default.<\/p>\n

 <\/p>\n

\"Route53<\/center><\/p>\n

Click\u00a0Create Record Set<\/strong>.<\/p>\n

3. Create a CNAME Record.<\/strong><\/h2>\n

Click here<\/a>\u00a0for details about about CNAMEs.<\/p>\n

Click\u00a0Create Record Set.<\/strong><\/p>\n

In the right window specify the\u00a0Name<\/strong>\u00a0field as\u00a0www<\/strong>. It will automatically append \u201cexample.com\u201d.<\/p>\n

If you want to map the\u00a0naked domain<\/strong>, e.g., example.com, leave the\u00a0Name<\/strong>\u00a0field blank.<\/p>\n

Select\u00a0CNAME-Canonical<\/strong>\u00a0name from the\u00a0Type<\/strong>\u00a0drop down menu.<\/p>\n

If you are mapping the record to a domain, keep the\u00a0Alias<\/strong>\u00a0at the\u00a0No<\/strong>\u00a0default value..<\/p>\n

By default,\u00a0TTL<\/strong>\u00a0is 300 seconds, but you can change it to meet your needs. If you are mapping the CNAME to an existing domain, then 24 hours is the ideal value. If you are mapping to ELB or S3, then 1 hour is the ideal value.<\/p>\n

In the\u00a0Value Box<\/strong>, specify the domain for which you want to map the\u00a0CNAME.<\/strong><\/p>\n

 <\/p>\n

\"canonical<\/center><\/p>\n

Leave the\u00a0Routing Policy<\/strong>\u00a0at the default value of\u00a0Simple<\/strong>.<\/p>\n

If you want to map the domain to an ELB or S3, then select\u00a0Yes<\/strong>\u00a0for the\u00a0Alias<\/strong>.<\/p>\n

On the\u00a0Alias Target box<\/strong>\u00a0select the ELB or S3 URL.<\/p>\n

 <\/p>\n

\"Route<\/center><\/p>\n

4. Create an MX Record<\/strong><\/h2>\n

The steps for creating an\u00a0MX record<\/strong>\u00a0are the same as for creating a CNAME record. In the\u00a0Type<\/strong>\u00a0field select\u00a0MX-Mail exchange<\/strong>\u00a0from the drop down menu.<\/p>\n
