High-level Route 53 RecordSet builder with traffic routing policies. **Supported Routing Policies:** - Simple (default) - Weighted (distribute traffic based on weights) - Failover (primary/secondary failover) - Geolocation (route based on user location) - Latency (route to lowest latency endpoint) - Multivalue (return multiple healthy IPs) **Default Settings:** - TTL = 300 seconds (5 minutes) - Type = A record **Rationale:** RecordSet provides advanced routing capabilities beyond simple A records. Essential for high-availability, multi-region architectures. **Use Cases:** - Active-passive failover - Traffic distribution across regions - Blue-green deployments - Load distribution
