Wasm Cloud

Abstract

1. Introduction

Using wasmCloud, you can run microservices, functions, and agents as ultra-dense, deny-by-default bytecode sandboxes that are far more secure and efficient than traditional containers — without changing your operational model. Workloads are WebAssembly components measured in kilobytes to low megabytes, starting in milliseconds, and portable across any conformant WASI runtime.

wasmCloud is a Cloud Native Computing Foundation Incubating project.

wasmCloud runs WebAssembly components and manages their capabilities. You decide exactly which interfaces each component can access. Everything else is denied.

2. Objective

wasmCloud is an open source Cloud Native Computing Foundation (CNCF) project that enables teams to build, manage, and scale polyglot apps across any cloud, K8s, or edge.

This project demonstrates how Rust, Kubernetes can be applied to a real-world Blockchain & Cloud Computing problem.

4. Technology Stack

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

• Rust toolchain (rustup / cargo)
• Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/wasmCloud/wasmCloud.git
cd wasmCloud

# Scaffold a new component
wash new https://github.com/wasmCloud/wasmCloud.git \
  --subfolder templates/http-hello-world \
  --name hello
cd hello

# Run in a hot-reload development loop
wash dev

curl localhost:8000
# Hello from wasmCloud!

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

• Add a CI/CD pipeline with GitHub Actions
• Deploy to a public test network or cloud free tier
• Add monitoring and cost alerts

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

1. Why does this problem need a blockchain or cloud-native design?
2. Explain the smart contract / infrastructure components and how they interact.
3. How are gas costs or cloud costs kept under control?
4. How is the system secured (keys, IAM, access control)?
5. How would the solution scale to many more users?
