What is Cloud Native WebAssembly?
summary
Fermyon’s Spin is an open source platform that compiles functions to WebAssembly and runs them as serverless units; the goodfirstissue bot gets ported from a Kubernetes long‑running service to a Spin/Wasm function using TinyGo, Spin’s key‑value store for credentials and caching, and Spin host HTTP functions for outbound Twitter/BlueSky calls. Cold starts drop from hundreds of milliseconds to sub 1 millisecond, observed end‑to‑end latency is ~50 milliseconds, and duplicate tweets are prevented via caching.
