Tutorial: Getting Started with Serverless WebAssembly and Spin
summary
Hands-on tutorial that uses Fermyon Spin to go from template to running service with spin new / spin build / spin up, building a Rust (or TypeScript) WebAssembly component, adding a static-file component, and deploying to Fermyon Cloud or Kubernetes via runwasi. Demonstrates key-value caching (local SQLite, Redis backend option), OCI packaging, and LLM integration (Llama models) to make a working magic eight ball app; cloud deploys finish in ~21s and LLM inferencing hits ~1s using A100 GPUs. Shows binary sizes (Rust WASM ~2 MB, AOT ~300 KB) and single-instance execution with external persistence.
