AWS Route 53 - Routing Policies - WeightedΒΆ

  • Control the % of the requests that go to each specific resource
  • Assign each record a relative weight:
    • traffic (%) = (weight for a specific record) / (sum of all weights)
    • Weights don't need to sum up to 100
  • [[DNS records]] must have the same name and type
  • Can be associated with health checks
  • Use cases: load balancing between regions, testing new application versions...
  • Assign a weight of 0 to a record to stop sending traffic to that resource
  • If all records have weight of 0 then all records will be returned equally
