• register and manage domains
• create various records sets on a domain
• implement complex traffic flows, e.g. Blue/green deploy
  • Blue/green deploy
• Continuously monitor records via health checks
• Resolve VPC’s outside of AWS

Alias Record

Instead of manually adding IPv4 addresses, you can create an Alias Record, that points to an existing Service/Resource of AWS.

• CloudFront distribution domain name
• Simple Storage Service — S3 website endpoint
• ELB Load Balancer
• Elastic Beanstalk
• Resource Record Set
• VPC Endpoint
• API Gateway

Routing Policies

seven different routing types

1. Simple Routing Policy — Default
   • One record and provide one or more IP addresses.
2. Weighted Routing Policies
   • Split traffic on different weights e.g. 15/85
3. Latency Based Routing Policy
   • Route53 checks the latency of every service and selects the one with the lowest latency
4. Failover Routing Policy
   • Automatically monitors health-checks to determine the status of end-points. If an end-point fails, traffic is directed to the secondary location.
