Route 53: DNS Service

AWS Cloud Practitioner to Architect: 0 to Hero

Amazon Route 53

Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service.

Key Routing Policies:

  1. Simple: One record to one resource.
  2. Weighted: Distribute traffic across resources (e.g., 20% to Test, 80% to Prod).
  3. Latency-based: Direct users to the region with the lowest latency.
  4. Failover: Disaster recovery (Active-Passive).
  5. Geolocation: Based on user location.
