Introduction

The web is becoming global by default.
Users expect pages to load instantly—regardless of where they are. But traditional server architectures are built around central regions:

• A single server (or cluster) in Virginia
• A CDN to cache static assets
• A backend thousands of kilometers away

This model can’t match the expectations of 2025:

• interactive pages must render quickly
• authenticated content must not be slow
• dashboards must maintain consistent latency
• APIs must remain responsive worldwide

Edge computing solves this.
