The following discussion would aim at describing the AWS route 53 service. Readers could find this discussion helpful for learning more about Amazon route 53 features and basic steps for its configuration. In addition, the discussion would also focus on ways to get started with route 53 on AWS. Most important of all, the discussion would present a comprehensive description of the benefits from Amazon route 53.

Understanding the basics of Route 53

The AWS route 53 service is the Domain Name System (DNS) service of AWS with higher availability and scalability. In addition, route 53 also facilitates health-checking and domain name registration web services. The design of route 53 aims at providing a highly reliable and cost-effective approach for routing end-users to Internet applications.

The DNS service helps in the translation of domain names into numeric IP addresses that computers use for connecting to each other. In addition, Amazon route 53 features help in a combination of DNS with health-checking services for traffic routing to healthy endpoints. In addition, you can also route traffic for independent monitoring or alarm on endpoints. 

Many people wonder why is it called route 53! The basic explanation for such doubts is the reference to TCP or UDP port 53. The ‘route’ element in the name route 53 is an inspiration from the iconic ‘Route 66” in the USA. You can also think of the ‘route’ part as an indication of the path for routing traffic to Amazon DNS. Now, you must have cleared your doubts about the name of the DNS service of AWS and why is it called route 53

The other functionalities of Amazon route 53 include purchasing and managing domain names alongside the configuration of DNS settings for specific domains. In addition, route 53 also offers effective connectivity between user requests and infrastructure running on AWS. The infrastructure running on AWS includes Amazon EC2 instances, Amazon S3 buckets, or Elastic Load Balancing load balancers. The applications of route 53 also help in routing users to infrastructure external to AWS. 

Routing policies

The next important addition in this amazon route 53 tutorial refers to the AWS routing policies. The different routing policies in route 53 include simple routing, geolocation routing, and latency-based routing. In addition, you can also find the weighted routing policy and failover routing policy with route 53. Let us take a look at the different routing policies in detail as follows.

Confused between Route 53 Policies? Here we bring the difference between Route 53 Latency-based Routing policy and Route 53 Geolocation Routing Policy.

Simple routing policy

As the name suggests, this is the most basic routing type. Simple routing involves a response to DNS queries only on the basis of values in the AWS route table. A simple routing policy is ideal in cases where you have a single resource performing a specific function for the concerned domain.

For example, if the application server has a public IP address like and you want a human-readable address on, then you can use a simple routing policy. Amazon route 53 can help in mapping to the concerned IP. As a result, every browser request for would then go to

Geolocation routing

According to amazon route 53 documentation, the geolocation routing policy helps in the allocation of resource targets according to the geographic location of the user. For example, as you can see in the image below, all queries from Europe should go to the IP address The routing of all queries in Europe to a server located in a similar physical region can help in the reduction of latency. Geolocation involves mapping of IP addresses to locations irrespective of the regions.

Latency-based routing policy

Applications hosted on EC2 instances in multiple regions could lead to higher latency. However, Amazon route 53 can help in reducing user latency through serving requests from regions with the lowest latency. The latency-based policy involves routing of traffic requests to servers that can respond with the lowest possible delay (latency). For example, you can run an application in multiple AWS regions with route 53 for automatic routing of users to regions that can deliver quickly.

Weighted Routing policy

Weighted routing policy is an important addition to this Amazon route 53 tutorial. The weighted routing policy involves the assignment of different numeric weights to various servers providing a specific web service. As a result, you can route a higher or lower percentage of incoming traffic according to the weights. The benefit of a weighted routing policy is clearly evident in load balancing and testing the new versions of software packages.

Failover routing policy

A failover routing policy helps in sending traffic to a server that is set as the primary server. However, the routing works only as long as the server is healthy. If the health checks find out that the primary server is failing, then traffic goes to a designated backup resource.

AWS Route Tables

Now, it is clearly evident that Amazon route 53 works by mapping end-user to a domain name or IP address. So, what is the record of these routes, or where are they stored? The answer is AWS route tables! AWS route table contains a collection of routes or rules for determining the destination for routing network traffic.

All subnets in a VPC should have an attachment with an AWS route table. The table then takes control over routing the concerned subnets. Subnets cannot associate with multiple route tables at a particular time. However, multiple subnets could connect with a single AWS route table. The AWS route table provides information about the destination IP address and the target resource, as shown in the image below.
