Are you tired of paying the cold-start latency and OS bloat tax when using containers for bursty, event-driven workloads?

Building Serverless Applications with WebAssembly & Spin is your hands-on guide to the third wave of cloud computing. This book provides a practical path to building lightweight and blazing-fast serverless applications using WebAssembly (Wasm) and Spin—the open-source framework that makes server-side Wasm genuinely accessible.

Rather than relying on disconnected \"Hello, World\" snippets, this book takes a comprehensive, project-based approach. You will build a end-to-end application from the ground up using Rust.

What You Will Learn:

The Wasm Paradigm: Grasp the core concepts of server-side WebAssembly, the Wasm Component Model, and why they matter for the future of cloud compute.
Development: Implement real requirements using the Spin SDK for Rust, Axum Serde and other common crates from the Rust ecosystem.
Wasm Component Composition: Build and Compose reusable WebAssembly components to reduce code duplication while increasing developer productivity.
Master Spin: Understand and Apply techniques provided by the CNCF Spin framework to get your inner loop tasks done with ease.
The Ultimate Promise of Portability: Take your finished application and deploy it to two radically different environments—the global edge with Akamai Functions and a Kubernetes cluster via SpinKube—without rewriting or recompiling a single line of code.

Whether you are a seasoned software architect exploring the edge or a developer looking to write highly optimized Wasm applications with Rust, this book will equip you with the tools to master the next generation of cloud development.
