Using Route53 ALIAS records


This is a special in-house type of DNS record specific to the Route53 service.

For an AWS user an Alias record is a great alternative to a CNAME (for supported resources).

Some of the main advantages are:

  • Aliases resolve directly to an IP address, saving the extra lookup which a CNAME would require

  • Alias records are supported at the zone apex, so you could create an alias which uses the top of a domain (for example mydomain.com)

  • Alias records allow advanced Route53 features such as weighted/latency/geo routing and failovers

  • There is no AWS cost associated with Alias lookups

Note

NB: A Route53 Alias record can currently only point to a limited set of AWS resources. For more information please see: http://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resource-record-sets-choosing-alias-non-alias.html
