DNS functions like a phone book, linking the IP address to the corresponding domain name.

AWS Route 53

Route 53 is a DNS web service that directs end users to internet applications hosted on AWS. It connects users and their requests to both AWS resources and external resources.

Route 53 includes a feature for managing DNS records, allowing you to register new domains and transfer existing ones. You can oversee all your domain names through Route 53.

The diagram illustrates the following process:

The company operates 3 EC2 instances within an Auto Scaling group.
This group is connected to an Application Load Balancer.
When a user requests data from the web application, Route 53 performs DNS resolution to determine the IP address.
The requested data is then sent back to the user.
The user’s request is routed to the nearest Edge Location via CloudFront.
CloudFront connects to the Application Load Balancer.
The Load Balancer forwards the packet to one of the EC2 instances.
