Simple, Failover, Geolocation, Geoproximity, Latency-based, Multivalue answer, and Weighted — each routes DNS responses differently.
Routes users to the Region that gives them the lowest network latency, improving performance for global applications.
Geolocation routes by the user's location; Geoproximity routes by the geographic distance between users and resources (with an adjustable bias).
Splits traffic across resources by assigned weights — useful for A/B testing and phased rollouts.
A global content delivery network (CDN) that caches content at edge locations to reduce latency and offload origins.
On a cache miss the edge fetches from the origin and caches it; later requests are served from the edge — lower latency and origin load.
Public hosted zones resolve names on the internet; private hosted zones resolve names within one or more VPCs.
