[AWS] Route 53
Route 53 configures and manages domains: domain registration, DNS (Domain Name System) service, and health checking. – DNS uses port 53. That is how the name comes from.
- Route 53 is commonly used with ELB (Elastic Load Balancer) and CloudFront.
- Split-View DNS option (Hosted zones) allows maintaining both a private and a public hosted zone with the same domain name.
- The private hosted zones are allowed with VPCs. Associated VPCs can see the interval version of a website by using the private zone’s A record.
- A public hosted zone holds the information about how to route the public domain name. The host (www) portion is not included in a public zone’s naming convention.
- In Route 53, the TTL (Time to Live) is the amount of time that the DNS resolver will cache the record.
- When creating an A record, you need to specify TTL, a routing policy, and IP values.
