Using AWS Route53 and EC2 Instances for Enhanced User Experience
Question
You are currently using Route53 for DNS routing.
Your application is hosted on EC2 Instances across multiple AWS Regions in an effort to improve performance for your users by serving their requests to provide them with the best and the fastest performance.

This is mentioned in the AWS documentation.
If your application is hosted in multiple Amazon EC2 regions, you can improve performance for your users by serving their requests from the Amazon EC2 region that provides the lowest latency.
For more information on Route53 routing policies, please refer to the below URL:
http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy.htmlTo ensure a better user experience, we need to route the user's request to the nearest AWS region where the application is hosted. In order to achieve this, we need to configure routing policies in Route53.
Here are the different routing policies available in Route53:
A. Geolocation Routing: This routing policy allows you to route traffic based on the geographic location of the user making the request. You can create a set of geolocation rules that define how traffic should be routed based on the continent, country, state, or city of the user. By using this routing policy, we can ensure that users are routed to the closest AWS region.
B. Latency-based Routing: This routing policy is used to route traffic to the AWS region that provides the lowest latency for the user making the request. This routing policy determines the latency between the user's location and each AWS region where the application is hosted. It then routes the user to the region that has the lowest latency.
C. Weighted Routing: This routing policy is used to distribute traffic across multiple AWS regions based on a specific weight assigned to each region. This routing policy is useful when we want to distribute traffic evenly across multiple regions or when we want to route a higher percentage of traffic to a specific region.
D. Failover Routing: This routing policy is used to route traffic to a standby or backup region in case the primary region is not available. This routing policy is useful when we want to ensure high availability of our application.
In this case, to ensure a better user experience and serve the users with the fastest performance, we need to configure latency-based routing policies in Route53. This will route the user's request to the nearest AWS region, based on the lowest latency, where the application is hosted.
