Terraform module for multi-provider DNS: define once, deploy to Route53 + Cloudflare

Mon, 16 Feb 2026 09:00:00 -0600

I manage 10 domains across Route53 and Cloudflare. When I set up multi-provider DNS on my first domain, every record had to be defined twice — once for each provider. The APIs are different enough that you can’t just copy-paste.

The duplication got old fast. So I wrote a module.

The problem

Route53 and Cloudflare represent the same DNS data differently:

MX records: Route53 bundles priority into the value string ("10 mx1.example.com"). Cloudflare splits it into a separate priority field.
