Amazon Route 53
Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service.
Key Routing Policies:
- Simple: One record to one resource.
- Weighted: Distribute traffic across resources (e.g., 20% to Test, 80% to Prod).
- Latency-based: Direct users to the region with the lowest latency.
- Failover: Disaster recovery (Active-Passive).
- Geolocation: Based on user location.
