Why I Believe Edge Computing is the Future of Web Deployment
Saying goodbye to traditional centralized servers. How deploying to the edge drastically improved my applications' latency and reliability.
The starting point
For the longest time, my deployment strategy was simple: spin up a server in a specific region (usually US-East), deploy my Node.js app, and hope my global users didn't complain too much about latency. Then, I discovered Edge Computing.
What I learned
When I first migrated one of my side projects to an Edge runtime using Vercel and Cloudflare, the results were staggering. My server logic was suddenly being executed physically closer to my users, whether they were in Tokyo, London, or Nairobi. The time-to-first-byte (TTFB) dropped to double-digit milliseconds universally. Writing code for the Edge did require some adjustments—I couldn't rely on certain Node.js core modules and had to be mindful of cold starts and execution time limits. But the tradeoff is absolute magic. I now architect my apps 'Edge-first', relying on distributed databases and edge-caching to deliver instant experiences worldwide.
