With Amazon CloudWatch Internet Monitor’s new traffic optimization suggestions feature, you can configure your Amazon Route 53 CIDR blocks to map your application’s client users to an optimal AWS Region based on network behavior.
Internet Monitor now provides actionable suggestions to help you optimize your Route 53 IP-based routing configurations. By leveraging the new traffic insights for your application, you can easily identify the optimal AWS Regions for routing your end user traffic, and then configure your Route 53 IP-based routing based on these recommendations.
Internet Monitor collects performance data and measures latency for your client subnets behind each DNS resolver. This enables Internet Monitor to recommend the AWS Region that will provide the lowest latency for your users, based on their locations, so that you can fine-tune your DNS routing to provide the best performance for users.
