A Greener, Cost-Effective Cloud with Serverless WebAssembly
summary
Shows that WebAssembly-based serverless actually starts in <1 ms versus microVM cold starts of ~125–500 ms, and produces tiny artifacts (~3 MB vs 200–400 MB containers). Demonstrates Spin CLI (spin new/build/up), Spin Registry push and Spin Cube on Kubernetes with a containerd shim, plus finicky-whiskers demo that fires hundreds of Wasm components. Cites real results: a customer shifts to ARM + Wasm and cuts compute cost ~60% and reports 43× faster batch execution.
