Route53
Route53 is Amazon's system for managing website addresses and directing internet traffic. Think of it like a phone book and traffic controller for websites. When someone types a website address, Route53 helps guide them to the right place. It's particularly useful for companies running their websites on Amazon's cloud services (AWS). The name comes from "Route" (directing traffic) and port "53" which is traditionally used for this type of service. Companies use Route53 to make sure their websites are reliable and fast for users around the world.
