How it works

• HA and scalable cloud DNS service
• You can combine with health-checking services to route to healthy endpoints
• You can also purchase and manage domains
• If you have stringent SLA add Global Accelerator, protecting users and applications from caching
• Routing options
  • Simple round robin
  • Weighted round robin
    Enables A/B testing using any number between 0 and 255
    ie: a:3/b:1 means a:75%, b:25%
  • Latency based routing (LBR) Routes to the fastest endpoint, based on actual performance measurements
• Health checks
• Geolocation routing
• Geoproximity routing (physical user-resource distance)

Alias
Similar to CNAME record, pointing to a LB

Traffic policies

• Graphic editor
• Rules can be based on location, latency…
  • Value -> ELB target goup
  • Value -> Weighted rule
    • 30% -> ELB TG
    • 70% -> IP
