Split-view

A.K.A split-horizon DNS.

Allows to use the same domain name for both internal and external uses.

Procedure:

  1. Create public and private hosted zones with the same name.
    Split-view DNS will still work if using an external DNS service for the public hosted zone.

  2. Associate one or more VPCs with the private hosted zone.
    Route 53 Resolver will use the private hosted zone to route DNS queries in the associated VPCs.

  3. Create records in each hosted zone.

    Records in the public hosted zone will control how internet traffic is routed.
    Records in the private hosted zone will control how traffic is routed inside the associated VPCs.

  4. Use Route 53 Resolver to perform name resolution of both the associated VPC and on-premises workloads.
