An e-commerce platform decomposed into independently deployable microservices. Each service lives in its own repository (wired in as Git submodules), owns its data store, and communicates through an API gateway and a message broker.

Architecture

ServiceResponsibilityStorage & messaging
ProductsCRUD API for the catalog with business-logic and data-access layers (EF Core) and xUnit testsMySQL, publishes events to RabbitMQ
OrdersOrder creation and querying, RabbitMQ consumers, Ocelot API gateway for cross-service callsMongoDB, Redis cache
UsersAuthentication and user retrieval with a Dapper data layerPostgreSQL
FrontendAngular 17 single-page app that talks to the services through the gateway—

Deployment

  • docker compose -f docker-compose-build.yaml up --build builds and starts the whole stack with seeded databases for local development.
  • Kubernetes manifests under aks/ run every service in Azure Kubernetes Service or any other cluster.

What it demonstrates

Service boundaries and polyglot persistence, asynchronous communication with RabbitMQ, API gateway patterns with Ocelot, containerization, and orchestrating a multi-service system with Docker Compose and Kubernetes.
