Vercel Enterprise Region Limits
Thom Krupa, co-founder of Bejamas, on building dynamic apps on the Jamstack
The important point is that location control used to be a premium infrastructure feature, not the default shape of modern frontend hosting. In the serverless model described here, code often ran in one chosen compute region near the app’s database, while the CDN only cached static files near users. That is why multi region placement mattered for large teams running global apps, and why edge compute changed the value proposition by moving lightweight code execution onto the CDN layer itself.

Vercel’s current model makes the split very explicit. Static assets are cached globally, standard functions default to Washington, D.C., and can be pinned to one or more regions. Pro now supports up to three regions, while Enterprise gets unlimited regions and failover controls. That pricing gate is the modern version of the enterprise only capability discussed in the interview.

Edge functions work differently from classic serverless functions. Instead of sending every dynamic request back to one origin region, edge runtime code executes in the location closest to the request. That is what makes personalization, auth checks, redirects, and first page render feel fast for users in Europe, Asia, and the U.S. at the same time.
-
Cloudflare Workers helped define this model. Workers run on Cloudflare’s global network using lightweight isolates instead of a single centralized server process. In practice, that means code can inspect a request, fetch data, rewrite a response, or render HTML close to the user, which is why Cloudflare became the reference point for edge computing in Jamstack.
The direction from here is clear. More web apps will split work between globally cached static content, edge code for per request logic, and a smaller amount of regional compute kept close to the database. The companies that win will be the ones that hide this complexity, so developers can choose speed at the edge without having to design a global infrastructure stack by hand.
