The various Route 53 routing policies are as follows:
- Simple routing policy – Use for a single resource that performs a given function for your domain, for example, a web server that serves content for the example.com website.
- Failover routing policy – Use when you want to configure active-passive failover.
- Geolocation routing policy – Use when you want to route traffic based on the location of your users.
- Geoproximity routing policy – Use when you want to route traffic based on the location of your resources and, optionally, shift traffic from resources in one location to resources in another.
- Latency routing policy – Use when you have resources in multiple locations and you want to route traffic to the resource that provides the best latency.
- Multivalue answer routing policy – Use when you want Route 53 to respond to DNS queries with up to eight healthy records selected at random.
- Weighted routing policy – Use to route traffic to multiple resources in proportions that you specify.
Geoproximity routing policy 还是有点不懂，需要进一步了解一下。
