What the Heck is Edge Computing Anyway?
summary
Edge compute means running serverless functions in a global CDN so dynamic responses execute near users, reducing latency. Practical limits are V8 isolates with tight CPU/memory/time budgets, no native TCP (databases need HTTP proxies), and the hard part is distributing data not code. Typical deployments cite 4,000 locations and hundreds of thousands of servers; common tools are CDN + edge key-value stores and replica caches. Works well for redirects, geo routing, fast static search and A/B, but not yet a drop‑in for entire apps.
