Enterprise Architectures & Patterns

This repository contains a collection of enterprise architectures and patterns, to illustrate the potential of Spin and WebAssembly (Wasm) for building real-world applications.

Each folder contains a self-contained example, including a high-level explanation of the pattern/architecture and instructions on how to build and run the particular Spin App(s).

Getting Started with Spin

If you haven't used Spin before, we highly recommend exploring the Fermyon Developer Home to get started. There you'll find everything from installing Spin on your local machine, over language-specific guides, to advanced techniques when building serverless Wasm applications.
