Your Guide for Patching Elastic Search!

What is Amazon Route 53?

Amazon Route 53 is a highly available and scalable authoritative cloud Domain Name System (DNS) service. It connects the Internet traffic to appropriate servers hosting the requested Web application.

AWS Route 53 takes its name from the Port 53, which handles DNS for both the TCP and UDP traffic requests, the term Route may signify the routing, or perhaps the popular highway naming convention in the USA.
