Routing Policies Flashcards
What is the Simple Routing Policy?
One record, multiple IP addresses. The user will be routed to an IP address in a random order.
What is a weighted routing policy?
Allows you to specify what percentage of requests go to each IP address.
20% -> us-east-1
80% -> us-west-1
What is latency based routing?
Routes requests to the destination with the lowest response time.
What is failover routing policy?
Used for active/passive failover. If the active site goes down, requests will be routed to the secondary destination.
What is geolocation routing policy?
Lets you choose routing destination based on the geographical request origin.
What is multivalue answer routing?
Allows you to create multiple record sets for the same URL, each routing to the IP address(es) that you define.
How would you set up a multivalue record set to ensure it doesn’t send requests to an unresponsive destination?
Setup a Route 53 health check monitoring. It will remove the record if the destination becomes unresponsive.
