Route 53 — DNS ir eismo maršrutizavimas
Route 53 is a managed DNS service (+ domain registration):
→ translates domain names (example.com) → IP addresses / AWS resources
→ ROUTING POLICIES (intelligent traffic direction):
- SIMPLE → one destination
- WEIGHTED → split traffic by percentage (e.g. A/B testing, gradual rollout)
- LATENCY → route users to the lowest-latency region (performance)
- GEOLOCATION → route by user location
- FAILOVER → route to a backup if the primary fails (HIGH AVAILABILITY)
→ HEALTH CHECKS → route away from unhealthy endpoints
