# Route 53

* &#x20;**Highly available and scalable cloud Domain Name System (DNS) web service.**<br>
* Choose a domain name and then register it with Route 53 **(domain registration)**.<br>
* Can do **health checks on AWS resources.**

**Route 53 Routing Policies:**\
&#x20;**- Simple Routing Policy - No health checks; simple DNS routing.**\
&#x20;**- Weighted Routing Policy - Distribute traffic unequally or equally across multiple instances** (kind of like load balancing but you define the balance).\
&#x20;**- Latency Routing Policy - Routes user to the closest server/instances for least latency.**\
&#x20;**- Failover Routing Policy - Health checks the primary instance and if it is unhealthy, it routes user to the "failover" instance.**
