Scriptable GeoDNS: leaving AWS for Bunny
Summary
Vincent Bernat describes migrating a GeoDNS and CDN setup from AWS Route 53 and CloudFront to Bunny CDN and Bunny DNS to reduce costs and gain scriptable DNS capabilities. The post covers geo-routing, scriptable DNS that selects the nearest servers, and the exploration of HTTPS records and the limitations that complicate their use. It also discusses ACME DNS with Hickory DNS for DNS-01 challenges, a hybrid approach to DNS responses, and notes on cost, tooling, and ongoing refinements.
