Taking WASI-Cloud-Core for a Spin
Talkat WasmCon 2023 · on Thursday, 2023-09-07· at 11:00· Grand Ballroom G, Hyatt Regency Bellevue, 900 Bellevue Way NE·
summary
WASI-Cloud-Core defines a small, portable surface for cloud services and is exercised by a working Spin + Wasmtime implementation that links guest modules to host capabilities as cheap function calls rather than sidecar RPCs. The demo builds a Python web crawler using key value get/set/delete/exists backed by Redis, messaging pub/sub and outgoing HTTP, publishes 32 messages while crawling, and runs unchanged across cloud and edge via Spin + Wasmtime, demonstrating low-latency startup and practical portability.
