Route 53                      

Route 53 is Amazon’s own Domain Name Service (DNS). A DNS provides a straight forward, yet crucial service by translating domain names (www.example.com) to IP addresses of specific computing resources (71.57.3.17). Computing resources communicate by sending packets to specific IP addresses, so knowing the right IP address for a given computing resource is critical.

                    

Route53 provides four DNS name servers that need to be identified to the domain name register, so that requests for DNS lookup are sent to an appropriate server to retrieve the right IP address.                     

 

Using Route 53

For the most part, using Route 53 is dead-simple. You register your domain name with a domain registrar, list the name servers that your domain name will use for address mapping, and then create subdomains and create zone records that list your subdomains and the IP addresses you want serving the subdomain service. Typically, this set-and-forget effort is completed early in a company’s or application’s life and is rarely touched there after. You’ll mostlikely use the AWS Management Console for this particular task.                                                   

Route 53 scope

Router 53 is a global service. Route 53 reduces to a minimum the network latency for DNS lookups. You don’t have to do anything to leverage this geographic distribution; AWS takes care of it for you.              

 

Route 53 cost

Route 53 is quite cost-effective:

✓ $.50 per hosted zone for the first 25 zones and $.10 per hosted zoneabove 25 zones

✓ $.50 per million DNS queries for the first billion queries per month and$.25 per million DNS queries above a billion

✓ $.75 per million latency-based queries for the first billion queries permonth and $.375 per million queries above that amount
