Scaling and Securing 12 Million Websites

on YouTube ↗32m

" summary

Jimdo migrated 12 million websites to Cloudflare in front of an AWS origin using Cloudflare SSL for SaaS, regional edge caching, cashtag headers to avoid purge rate limits, and Argo Tunnel to block direct origin access. The migration removed Redis/ELB hotspots, enabled hierarchical cache hits (improving performance in Japan), survived a large DDoS on free sites during cutover, and reduced AWS costs by about 40% while improving web delivery SLOs.
