What is edge computing and how does Cloudflare Workers compare to traditional hosting?
Edge computing runs code at servers physically close to users (edge nodes) rather than a central data center. Cloudflare Workers execute JavaScript code at 200+ global PoPs — your code runs in Mumbai for Indian users, in London for UK users — reducing latency from 100ms to under 5ms for compute operations. Use Cloudflare Workers for: A/B testing without origin server round trips, personalization at the edge (show user's region-specific content instantly), authentication verification before requests reach origin, API gateway with rate limiting and caching logic. Limitations: Workers has a 10ms CPU limit per request (not suitable for heavy computation), limited Node.js API compatibility, and no persistent storage (use Workers KV or Durable Objects). For India: Cloudflare has Mumbai and Chennai PoPs — Workers executing in Mumbai serve Indian users with sub-10ms compute response. Compare to Connect Quest VPS (compute in NE India DC): for NE India users, Connect Quest origin may actually be faster. The ideal stack: Connect Quest VPS as origin + Cloudflare Workers at edge for global users. Explore at connectquest.co.in.
