Route 53 offers a couple of other useful routing policies, so you should have a think about which best suits you:

• Latency-based routing: This policy makes the Route 53 DNS servers respond to you with IP addresses that provide the lowest latency. This will not necessarily be the endpoint geographically closest to you.
• Weighted routing: This allows you to divvy up your traffic between endpoints based on a weighting system. You might have a 50/50 split between two regions, or you may elect to have a 90/10 ratio instead.
