Episode notes
Why CloudFront Solved Global Reach
- Booking.com moved from Europe-centric datacenters and mini-pops to a globally distributed CloudFront edge to serve users worldwide.
- CloudFront's global presence, AWS integrations, and managed features met performance, security, and operational requirements.
Edge Reverse Proxy Cuts Latency
- Using CloudFront as a reverse proxy reduced connection setup latency for remote users even for dynamic, non-cacheable traffic.
- Keeping long-lived origin connections meant 99.7% of requests reused existing connections, improving latency significantly.
Measure Before You Migrate
- Build comprehensive end-to-end observability before changing infrastructure so you can measure impact.
- Collect server-timing headers and trace browser-to-origin metrics to pinpoint latency gains and reused connections.
