## What Route 53 does

**Route 53** is AWS's DNS service — it resolves domain names to IP addresses or AWS resources, and can also register domains directly.

## Routing policies at a glance

**Simple** (one answer), **weighted** (split traffic by percentage, e.g. for canary releases), **latency-based** (send to the fastest region), **failover** (switch to a backup if health checks fail).

**Quiz:** You want 5% of traffic to hit a new version for a canary test. Which Route 53 policy fits?

- [ ] Simple routing
- [x] Weighted routing
