What is ROUTE 53?

Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. The “53” specified is the port number designated in the AWS, it serves as an interconnection between IP and the domain.

Why ROUTE 53?

Route 53 is used to perform functions namely:-

  1. i) Register domain names.
  2. ii) Route internet traffic to the resources of your domain.

iii) Check the health of your resources.

i) Register domain names:

It is a known fact that any domain names have to be registered in order to show itself in the world wide web. The AWS ROUTE 53 package includes the registering of your domain name.

  1. First, a static URL is made to obtain.
  2. Then the obtained address is allocated as a new address.
  3. The address is allocated under “VPC”.
  4. A new IP address is then formed which in the next process is chosen as the associated address.
  5. Then, set an instance name accordingly.
  6. This generates a new IP address.
  7. Verify the IP address in the browser.

ii) Route internet traffic to the resources of your domain:

When a user opens a web browser and enters your domain name in the address bar, Route 53 helps connect the browser with your website or web application.

All computers on the internet communicate with one another by using numbers. These numbers, known as IP addresses, are in one of the following formats:

When you open a browser and go to a website, you don’t have to remember and enter a long number like that. Instead, you can enter a domain name like example.com and still end up in the right place. A DNS service such as Amazon Route 53 helps to make that connection between domain names and IP addresses.

iii) Check the health of your resources:

Route 53 sends automated requests over the internet to a resource, such as a web server, to verify that it’s reachable, available, and functional.

You can set health checks to query for a particular string, and can target a specific URL.

 

These health checks serve two purposes.

  1. The first goal is DNS failover. This ensures that only healthy endpoints are returned to requesters.
  2. The second is to generate CloudWatch metrics for alarms, trend reports, or triggering Lambda functions at certain thresholds.

Summary:

Pro’s of ROUTE 53:

Intuitive interface: everything you need is right in front of you. If you know what you’re doing it’s really easy to use. Also, response time is super fast.

Support of elastic DNS is also great as to set up something like that manually you need experience while with Route53 you get it ready-made.

 

Con’s  of ROUTE 53:

 

Admin permissions are not very intuitive. It is very versatile and you can set up almost anything you need. But it’s not very easy to use.

To use the API you need to read a lot of documentation and on many pages, there is no single guide. Documentation is really complicated. On the positive side, there are many libraries using the API so you may avoid the need for reading lots of documentation.
