Route 53 Routing Policies (2/2)

In part 1, I explored the first four routing policies used by Route 53 when responding to DNS queries. These are the rest of the policies:

• Geolocation routing: based on the geographic location of the user, Route 53 will respond accordingly. For example, this is useful for compliance or content distribution restrictions.

• Geoproximity routing: not to be confused with geolocation, in this case a bias weight is established to AWS resources allocated in specific regions. In other words, this policy takes into consideration the location of the user and the location of the AWS resource being queried for.

• IP-based routing: CIDR blocks are allocated to different AWS resources, and depending on the user's IP address, different DNS responses will be provided.

• Multi-value routing: based on health checks, Route 53 is able to return multiple records for a single resource. For example, a website with three different IP addresses.
