You can use Amazon Route 53 Traffic Flow to assemble a wide range of routing scenarios, from adding a simple backup page in Amazon S3 for your website, to building sophisticated routing policies that consider an end user’s geographic location, proximity to an AWS region, and the health of each of your endpoints. Amazon Route 53 Traffic Flow also includes a versioning feature that allows you to maintain a history of changes to your routing policies, and easily roll back to a previous policy version using the console or API.

With Amazon Route 53 Traffic Flow, there are no minimum usage commitments or up-front fees. You pay only for the Amazon Route 53 Traffic Flow policies you use to manage traffic routing, and the number of queries that the Amazon Route 53 DNS service answers for each of your domains.
