Look inside

To support its rapid growth, e-commerce company UMET Inc. relies on lightweight, interdependent, cloud-native microservices written in Rust that can compute sales tax rates and e-commerce order totals. As a developer at UMET, it’s up to you to integrate these microservices with existing order systems. To do that, you’ll need to turn the order total microservice into a database-backed stateful service. You’ll build and test the microservice in Docker and model the application data into relational database records. You’ll connect the microservice application to a MySQL database server, and you’ll use Docker to compose and manage all components of the microservice. When you’re done, you’ll have built an order management microservice in Rust that can read and save data from UMET’s MySQL relational databases and later serve as a template for other UMET microservices.

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

prerequisites

This liveProject is for developers interested in learning how to create cloud-native microservices that can read and save data from a MySQL database. To begin these liveProjects you’ll need to be familiar with the following:

TOOLS
  • Rust programming basics (syntax, standard libraries, and building tools such as cargo and crates.io)
  • 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)
TECHNIQUES
  • 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
