Living on the Edge
summary
Shows how to move Next.js middleware to the edge to serve a cacheable static homepage with a geo-targeted banner (example: Ada’s Pet Supplies giving 50% off to Canadians) and compares data strategies: PlanetScale backhaul with Vitess connection pools (claimed million open connections), Cloudflare Durable Objects for strong consistency, Cloudflare Smart Placement to run functions near databases, Hyperdrive caching reads, and physical compute via AWS Snowball for offline sites; notes ~150ms per ocean hop and energy benefits of edge caching.
