Latency is the silent killer of SaaS conversion. As user bases become more global, delivering a snappy experience from a single central data center is no longer viable. Edge computing is the answer.
Why the Edge Matters
By moving computation closer to the user, we can reduce round-trip times from hundreds of milliseconds to just a few dozen. This isn't just about speed; it's about reliability. If one edge node goes down, the system can automatically reroute traffic to the next closest one.
Implementing Edge Functions
Modern platforms like Vercel and Cloudflare have made it incredibly easy to deploy logic at the edge. However, the true challenge lies in database consistency. Distributed databases like Turso or Neon are helping solve this by bringing the data itself to the edge.
