Amazon Route 53

Amazon Route 53 is ideally a DNS, short for, domain name system. Its job is to translate the domain name such as that is easily read by humans into a machine-readable format, also popularly known as IP address. The domain names are converted into numeric format because they help computers quickly and easily form a connection with one another. It is, therefore, simplifying cloud routing the users to various internet applications.

What is DNS

The domain name system (DNS) is a naming system that locates and converts web domain names into Internet Protocol (IP) addresses. The domain name system translates a website's name into a numeric IP address that a machine can use to find that website.

When someone types "" into a browser, a server starts working to match that name to an IP address. The idea of an IP address is comparable to

DNS is used to swiftly supply the data needed to connect users to remote hosts during web surfing and many other online activities. DNS mapping is organized in a hierarchy of authority across the internet.

4 types of servers are involved in helping a web page load. They are as follows:

  • DNS Recursor
  • Root Nameserver
  • TLD Nameserver
  • Authoritative Nameserver

How They Work Amazon Route 53

In short, AWS Route 53 is a DNS management service for Amazon's public cloud services and workstations. User queries are routed through the AWS Route 53 DNS service to  Amazon EC2 instances,  Amazon S3 buckets, ELB load balancers, and other AWS infrastructure.

It is intended to increase commerce consistently and cost-effectively. AWS Route 53 uses a worldwide network of DNS servers to respond to all requests.

Domain queries are directed to the closest DNS server, which responds back with the maximum possible performance. One can set up and oversee public DNS using the AWS management console or a simple API.

We may also use AWS Route 53 to register an existing domain name. It assists in such a manner that the person simply has to pay for domain maintenance and registered domains in AWS.

When an individual user Route 53 DNS to reach a web server, the following process takes place:

Step 1: The user visits a web address handled by Route 53 which takes them to an AWS supported device

Step 2: AWS Route 53 routes the user’s request to their DNS resolver who in turn forwards it to a DNS root server.

Step 3: The DNS resolver then directs the user's requests to the TLD name servers.

Step 4: Here, the DNS resolver obtains the 4 authoritative AWS Route 53 name servers which are responsible for hosting the domain’s DNS zone.

Step 5: After selecting one of the 4 name servers, the DNS resolver queries data for the requested web address.

Step 6: The selected Route 53 name server then looks for information on the requested website, including its IP address, on the DNS zone and later returns it to the DNS resolver.

Step 7: The DNS resolver stores the IP address at a local space, and forwards it to the web browser of the user.

Step 8: The browser contacts Amazon hosted services, for instance, the web server, using the returned IP Address.

Step 9: Finally, the website is displayed to the user through their browser.

Benefits of Amazon Route 53

AWS Route 53 is widely used for its scalability and reliability. It has various advantages over its counterparts. Let us look at some of its benefits below:

Low Cost Domain Registration

AWS Route 53 allows users to select and register domain names from domain options like .com, .in, .org, etc. They have enabled the user to transfer their existing domain name if they want it to get managed by Route 53.

Easy Routing Policy

A straightforward routing policy. This policy uses AWS Route 53 to match your website name to your IP address, which is the easiest and most used routing type. Any further browser queries for that website would be forwarded to the corresponding IP address.

Failover Policy

An Amazon Route 53 failover policy automatically transfers users to a selected backup service or alternate provider in the event of an outage as identified by health screening.

Geographical DNS

This policy directs users to destinations depending on resource targets based on their identified geographical area.

Health Checkups

AWS Route 53 performs health screenings and analyzes the health and efficiency of software. When Amazon Route 53 identifies an interruption, it transfers customers to a healthy source.

Latency Routing

A latency-based policy directs users and traffic to the AWS region with the minimum latency.

Highly Reliable

Route 53 is based on AWS infrastructure and is extremely dependable. Its distributed nature in relation to DNS servers aids in ensuring a continuous capacity to route end-user applications.

High Scalability

Route 53 is designed in such a manner that it can handle massive volumes of requests even without the user having to engage.

Private DNS 

It allows Amazon VPC users to specify bespoke domain names while preserving DNS information private. Private DNS records make it simple to redirect traffic and build private hosted zones with domain names controlled inside your VPCs.

Limitations of Amazon Route 53

We have looked at some of the benefits of Amazon Route 53. However, it also comes with some disadvantages. Let us throw some light on what those are:

DNSSEC Not Supported

The DNSSEC standard is not supported by AWS Route 53. DNSSEC defends against man in the middle and other DNS threats.

Single Point of Failure

AWS Route 53 becomes a single point of failure when used in conjunction with other Amazon web services. This is a difficulty for disaster recovery on AWS Route 53 and related difficulties.

Limiting DNS Load Balancing

AWS Route 53 load balancing services are limited to basic load balancing and missing extensive policy support and enterprise-class functionality.

No Zone Transfer Support

Private zone transfers are not supported. Regardless if you have registered the root level domain "", you cannot designate AWS Route 53 as the authoritative source for ""


Despite the fact that there are solutions for routing Route 53 DNS inquiries to external servers, the queries must still be passed to external servers after reaching out to Amazon infrastructure, resulting in delays.

High Priced  

The service is costly, especially for enterprises using Route 53 with non-AWS endpoints/services. The visual editor is particularly expensive; it costs $50 per month in addition to the cost of queries for each record type to which a visual editor policy is applied.

Through this blog, we could get an in-depth idea of what AWS Route 53 is, how they work and what are its pros and cons. In the end, it is your decision to go for it. There are, however, many alternate options to AWS Route 53 for handling DNS within the AWS environment. To produce the same results as Amazon Route 53, any third-party DNS provider instead of Route 53 should be able to readily route individuals and traffic to the best data center, endpoint, or area.

AWS Route 53 competitors include Cloudflare DNS, Google Cloud DNS, Azure DNS, and GoDaddy Premium DNS for hosting cloud services. Built-in interaction with tools to automate and deploy, which incorporates hard data regarding your AWS servers and their criteria, such as availability, load, and geographical region, can then enable other tools to route traffic based on the criteria selected.
