3. What is Route 53? Route 53 is AWS’s authoritative Domain Name (DNS) service DNS translates domain names (like www.amazon.com) into IP addresses – think of it as a “phone book” for the internet DNS is a Tier-0 service – availability is most important We chose the name “Route 53″ as a play on the fact that DNS servers respond to queries on port 53 3 © 2011 Amazon.com, Inc. and its affiliates.

7. Latency Based Routing (LBR) Run multiple stacks of your application in different EC2 regions around the world Create LBR records using the Route 53 API or Console • Tag each destination end-point to the EC2 region that it’s in • End-points can either be EC2 instances, Elastic IPs or ELBs Route 53 will route end users to the end-point that provides the lowest latency 7 © 2011 Amazon.com, Inc. and its affiliates.

Since we’veimplemented this, we’ve reduced page load times for our endusers by 1-2 seconds. We also learned which servers themajority of users were near (in terms of latency) which ismaking us rethink our general server deployment strategy.” Ryan Lower, Academia.edu 15 © 2011 Amazon.com, Inc. and its affiliates.
