  • Simple Routing
  • Latency-based Routing
  • Geolocation Routing

Simple Routing

Route 53

Simple routing responds to DNS queries based only on the values in AWS route table. Use the simple routing policy when you have a single resource that performs a given function for your domain.

Latency-based Routing

Route 53 demo

If an application is hosted on EC2 instances in multiple regions, user latency can be reduced by serving requests from the region where network latency is the lowest. Create a latency resource record set for the Amazon EC2 resource in each region that hosts the application. Latency will sometimes change when there are changes in the routes.
