Demystifying Serverless Functions and Edge Computing

Edge computing moves compute workloads from distant centralized data centers to geographically distributed point-of-presence (PoP) locations closest to the end user. This minimizes round-trip latency and accelerates dynamic API responses.

1. Cold Starts: V8 Isolates vs Docker Containers

Traditional serverless functions (like standard AWS Lambda) spin up micro-containers, resulting in cold starts of 200–800ms. Edge runtimes (like Cloudflare Workers) utilize V8 Isolates, achieving instantaneous sub-5ms cold startup times.
