Look inside

UMET Inc.’s mission to modernize its software infrastructure has been a great success. The e-commerce company now uses Rust microservices that run in lightweight Wasm containers so that they can be deployed anywhere in the cloud. However, as more microservices are created, the overhead for managing them is becoming a problem. Using the Distributed Application Runtime (Dapr) sidecar, a commonly used design pattern, you’ll create a proof of concept (PoC) that demonstrates the pattern’s benefits, including reducing the complexity of connecting multiple microservices and infrastructure services (e.g. databases and web proxies). When you’re finished, you’ll have refactored UMET’s microservices to work with Dapr, reducing the overhead required to manage them.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

project author

Michael Yuan

Dr. Michael Yuan is the founder and maintainer of the open-source WasmEdge project—one of the most popular WebAssembly runtimes for server and edge applications. He’s the author of five books on software engineering and a frequent speaker at conferences, including KubeCon, Open Source Summit, QCon, and Rust Conf. He’s also the creator of, a serverless automation platform for AIOps and LLMOps. He holds a PhD in Astrophysics from the University of Texas at Austin and has been designing and implementing enterprise applications and server-side software infrastructure for over 20 years.


This liveProject is for developers who are interested in learning how to refactor microservices with Dapr, reducing complexity and management overhead. To begin these liveProjects you’ll need to be familiar with the following:

  • Rust programming basics (syntax, standard libraries, and building tools such as cargo and
  • Linux basics (use the command line, sudo, and open/map ports to the outside world)
  • Basics of Git, GitHub, and GitHub Actions
  • GitHub account (registration is free)
  • Rust and Cargo toolchain
  • WasmEdge Runtime
  • Docker basics (commands, Dockerfile structure, Docker Compose, and the docker-compose.yml file)
  • Basics of typical HTTP-based web services
  • Basics of the 3-tier architecture for web applications
  • Exchange data with a web service using JSON
  • Use JSON in the frontend JavaScript framework

you will learn

In this liveProject, you’ll learn how to refactor microservices with Dapr, reducing complexity and management overhead.
