Amazon Route 53 Traffic Flow
Amazon Route 53 Traffic Flow is a feature that allows you to easily create and manage complex routing configurations using visual tools. Traffic Flow combines health checks and routing policies into reusable configurations called traffic policies. You can create a traffic policy using the Route 53 Management Console, specify routing rules, define failover and load balancing behaviors, and associate a policy with a domain or subdomain. Traffic Flow evaluates the policy's rules in real-time and routes users accordingly, ensuring that your clients always have the best possible experience. Traffic Flow is suitable for a wide range of applications, such as optimizing latency, load balancing between multiple resources, or ensuring high availability through failover configurations. Note that Traffic Flow is billed separately from other Route 53 services.
