🌍 Overview
Welcome to the Ecommerce Enterprise Series, where we will design, develop, and deploy a real-world enterprise-grade e-commerce system from scratch — using .NET 8, Angular, Docker, Jenkins, Redis, and RabbitMQ.
The goal of this series is not just to build another sample CRUD project — but to create a production-ready enterprise application, following Clean Architecture, DevOps automation, and best practices used in real-world SaaS systems.
This series is ideal for developers who want to move beyond tutorials and understand how real applications are structured, scaled, and deployed in production.
🎯 Objectives
By the end of this series, you’ll learn how to:
Design a modular, enterprise-grade architecture using Clean Architecture principles.
Work with multiple databases (MySQL, SQL Server, PostgreSQL) in the same system.
Integrate Redis caching and RabbitMQ messaging for performance and scalability.
Implement authentication & authorization using JWT and Azure AD.
Build a Backoffice UI in Angular for managing products and users.
Dockerize the entire solution for local and production deployments.
Set up Jenkins CI/CD pipelines for automated build and deployment.
Apply logging, monitoring, and production best practices for reliability and security.
📚 Lesson Plan
| # | Lesson Title | Description |
|---|---|---|
| Lesson 0 | Ecommerce System Overview & Backoffice Setup | Introduction to the Ecommerce Application: overview of the storefront and backoffice modules, defining high-level features, and environment setup. |
| Lesson 1 | System Architecture & Design Principles | Deep dive into clean architecture, layered design, separation of concerns, and scalability considerations. |
| Lesson 2A | Project Setup in .NET 8 (Solution & Configuration) | Creating the base solution, API project, folder structure, dependency injection, and environment configuration. |
| Lesson 2B | Implementing Domain Layer (Entities & Value Objects) | Designing and implementing domain entities following clean architecture principles in .NET 8. |
| Lesson 2C | Implementing Repository Interfaces (Domain & Infrastructure Layers) | Defining repository interfaces in the domain layer and implementing them in the infrastructure layer using dependency inversion. |
| Lesson 2D | Implementing Application Services (Service Layer and DTOs) | Building the service layer to handle business logic, creating Data Transfer Objects (DTOs), and mapping between layers. |
| Lesson 2E | Implementing Controllers (Presentation Layer) | Creating RESTful controllers to expose application services via APIs and ensuring proper separation of concerns. |
| Lesson 3 | Integrating MySQL (First Database) | Setting up MySQL, creating initial migrations, and implementing CRUD operations for base entities. |
| Lesson 4 | Adding SQL Server Support (Multi-Database Setup) | Configuring Entity Framework Core for multiple providers and supporting SQL Server alongside MySQL. |
| Lesson 5 | Working with PostgreSQL | Configuring Entity Framework Core for multiple providers and supporting PostgresSQL alongside MySQL and SQL Server |
| Lesson 6 | Redis Caching for Performance Optimization | Installing and configuring Redis; caching responses, queries, and improving API performance. |
| Lesson 7 | Message Queues with RabbitMQ | Implementing event-driven communication, background jobs, and asynchronous processing. |
| Lesson 8 | Authentication & Authorization in .NET | Implementing JWT-based authentication, role-based authorization, and optional Azure AD/IdentityServer integration. |
| Lesson 9 | Building the Backoffice Web App (Angular/React) | Creating a modern admin UI for managing products, orders, and users, integrated with the backend API. |
| Lesson 10 | Dockerizing the Full Stack Application | Writing Dockerfiles for .NET and Angular/React, setting up docker-compose for local orchestration. |
| Lesson 11 | Continuous Integration with Jenkins | Creating CI/CD pipelines in Jenkins for automated build, test, and deployment workflows. |
| Lesson 12 | Structured Logging & Monitoring | Configuring Serilog with Seq or ELK Stack for centralized structured logging and observability. |
| Lesson 13 | Centralized Error Handling & Validation | Using middleware for error handling, implementing FluentValidation, and maintaining consistent API responses. |
| Lesson 14 | Cloud Deployment (Azure / AWS) | Deploying backend, frontend, and database to the cloud with managed infrastructure services. |
| Lesson 15 | Production-Ready Best Practices | Applying final production optimizations: security headers, health checks, scaling, monitoring, and backups. |
⚙️ Environment & Tools Setup
Before we start building, make sure you have the following tools installed:
🧰 Development Tools
