Truly Portable Code: Serverless WebAssembly in a Distributed World

on YouTube ↗01h 03m

" summary

Demonstrates building a Rust URL-shortener compiled to WebAssembly with the Spin CLI, running locally (WebAssembly .wasm built to target/release), using a local SQLite-backed key/value store and then swapping to Redis in Kubernetes via runtime config; deploys an OCI-packed Spin app (pushed to ttl.sh) to AKS with SpinKube on AKS using the containerd shim and Spin operator with four replicas, showing local and Kubernetes runs succeed while Fermyon Wasm Functions (private preview) sometimes returns 503s during the demo.
