Keynote: Coding on the Edge
summary
Edge execution runs V8 (with WebAssembly) inside the network so JavaScript and compiled code execute in 154 locations worldwide with single-digit ms cold starts. Real deployments include a map tile service that races Google vs Backblaze and returns the fastest tile at the edge, a seven-line data‑loss‑prevention check that blocks leaked canary values before they hit origin, JWT verification on the edge to reject unauthorized drone images, and a globally synchronized key‑value store for low‑latency apps.
