Amazon Route 53

Route 53 provides authoritative DNS with health checks, failover, weighted, latency-based and geo routing policies, plus domain registration.

• Manage public and private DNS zones
• Blue/green and canary cutovers via weighted records
• Domain failover with health checks

1. Register or transfer a domain (or create a Hosted Zone for an existing one).
2. Add A/AAAA Alias records pointing to ALB, CloudFront, or S3 website endpoints.
3. Create health checks for endpoints and link to records for failover.

• QA chaos test: disable an endpoint and verify Route 53 failover routes traffic to the secondary region.
• Use weighted records to shift 5% of synthetic test traffic onto a new release.
