Answer:
To route traffic to multiple resources in proportions that you specify, you can use the Weighted Round Robin routing policy in Amazon Route 53.
With this policy, you can assign a weight to each resource record set in a weighted resource record set group. Route 53 then routes traffic to the record sets in the group in proportions that reflect their weights.
For example, suppose you have two resource record sets in a weighted resource record set group:
Record set A: weight 10
Record set B: weight 20
With this configuration, Route 53 routes twice as much traffic to record set B as it does to record set A, because the weight of record set B is twice that of record set A.
To use the Weighted Round Robin routing policy, you first create a weighted resource record set group in Route 53, and then you add resource record sets to the group. You can specify a weight for each resource record set when you create it or edit it.
Note that the Weighted Round Robin routing policy is just one of several routing policies available in Route 53. Other routing policies include Simple Routing, Latency Routing, and Failover Routing, among others. It's important to choose the routing policy that best meets the needs of your specific use case.
