Amazon Route 53
Route 53 provides DNS hosting, health checks, and traffic routing policies.
What This Service Solves
Route 53 provides DNS hosting, health checks, and traffic routing policies.
- Use Route 53 for public/private hosted zones, routing policies, failover records, and domain registration.
When You Should Not Use It
- Do not confuse DNS routing with packet routing inside a VPC route table.
What AWS Manages and What You Manage
AWS manages authoritative DNS service. You manage records, TTLs, routing policies, health checks, and zone permissions.
Security Implications
Protect hosted-zone changes with IAM, MFA, change review, and DNSSEC where appropriate.
Availability and Scaling
Failover, latency, weighted, and geolocation policies help steer traffic, but targets must also be healthy.
DNS TTL influences cutover speed and client caching behavior.
Cost Behavior
Hosted zones, queries, health checks, and resolver endpoints can create cost.
Common Integrations
- CloudFront
- ELB
- S3 website endpoints
- VPC private zones
