Vercel's application delivery system is a comprehensive framework-defined infrastructure that analyzes the codebase and intelligently provisions cloud resources. When users access apps served by Vercel, their network requests are handled by a dedicated network designed for speed, reliability, redundancy, and scalability. Anycast routing directs each request to the optimal Point of Presence across 100+ global locations, minimizing latency for the user's first interaction with Vercel Infrastructure. The system also features a defense-in-depth firewall with multiple layers, including Network-layer 3, Transport-layer 4, and Application-layer 7 protections, as well as customizable application protection through the Web Application Firewall (WAF). Advanced routing is handled through redirects, rewrites, and Edge Middleware, which can inject business logic and make real-time adjustments to request flow. The system also includes caching at the edge to speed up responses and Vercel Functions for scalable and dynamic compute. Overall, Vercel's platform powers web apps that feel as smooth as native apps, delivering fast, reliable web experiences with scale globally from your first commit.
