Lesson 0 — 🧱 Ecommerce Enterprise Series — From Code to Cloud

🌍 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:

  1. Design a modular, enterprise-grade architecture using Clean Architecture principles.

  2. Work with multiple databases (MySQL, SQL Server, PostgreSQL) in the same system.

  3. Integrate Redis caching and RabbitMQ messaging for performance and scalability.

  4. Implement authentication & authorization using JWT and Azure AD.

  5. Build a Backoffice UI in Angular for managing products and users.

  6. Dockerize the entire solution for local and production deployments.

  7. Set up Jenkins CI/CD pipelines for automated build and deployment.

  8. Apply logging, monitoring, and production best practices for reliability and security.

📚 Lesson Plan

#Lesson TitleDescription
Lesson 0Ecommerce System Overview & Backoffice SetupIntroduction to the Ecommerce Application: overview of the storefront and backoffice modules, defining high-level features, and environment setup.
Lesson 1System Architecture & Design PrinciplesDeep dive into clean architecture, layered design, separation of concerns, and scalability considerations.
Lesson 2AProject Setup in .NET 8 (Solution & Configuration)Creating the base solution, API project, folder structure, dependency injection, and environment configuration.
Lesson 2BImplementing Domain Layer (Entities & Value Objects)Designing and implementing domain entities following clean architecture principles in .NET 8.
Lesson 2CImplementing Repository Interfaces (Domain & Infrastructure Layers)Defining repository interfaces in the domain layer and implementing them in the infrastructure layer using dependency inversion.
Lesson 2DImplementing Application Services (Service Layer and DTOs)Building the service layer to handle business logic, creating Data Transfer Objects (DTOs), and mapping between layers.
Lesson 2EImplementing Controllers (Presentation Layer)Creating RESTful controllers to expose application services via APIs and ensuring proper separation of concerns.
Lesson 3Integrating MySQL (First Database)Setting up MySQL, creating initial migrations, and implementing CRUD operations for base entities.
Lesson 4Adding SQL Server Support (Multi-Database Setup)Configuring Entity Framework Core for multiple providers and supporting SQL Server alongside MySQL.
Lesson 5Working with PostgreSQLConfiguring Entity Framework Core for multiple providers and supporting PostgresSQL alongside MySQL and SQL Server
Lesson 6Redis Caching for Performance OptimizationInstalling and configuring Redis; caching responses, queries, and improving API performance.
Lesson 7Message Queues with RabbitMQImplementing event-driven communication, background jobs, and asynchronous processing.
Lesson 8Authentication & Authorization in .NETImplementing JWT-based authentication, role-based authorization, and optional Azure AD/IdentityServer integration.
Lesson 9Building the Backoffice Web App (Angular/React)Creating a modern admin UI for managing products, orders, and users, integrated with the backend API.
Lesson 10Dockerizing the Full Stack ApplicationWriting Dockerfiles for .NET and Angular/React, setting up docker-compose for local orchestration.
Lesson 11Continuous Integration with JenkinsCreating CI/CD pipelines in Jenkins for automated build, test, and deployment workflows.
Lesson 12Structured Logging & MonitoringConfiguring Serilog with Seq or ELK Stack for centralized structured logging and observability.
Lesson 13Centralized Error Handling & ValidationUsing middleware for error handling, implementing FluentValidation, and maintaining consistent API responses.
Lesson 14Cloud Deployment (Azure / AWS)Deploying backend, frontend, and database to the cloud with managed infrastructure services.
Lesson 15Production-Ready Best PracticesApplying 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

  • Visual Studio 2026 / VS Code

  • .NET 8 SDK

  • Node.js (v18+) & Angular CLI

  • MySQL / SQL Server / PostgreSQL

  • Redis Server

  • RabbitMQ

  • Docker Desktop

  • Jenkins (Local or Cloud)

  • Postman / Thunder Client for API testing

🚀 Outcome

By the end of the series, you’ll have a fully functional, production-grade enterprise application, with:

  • ✅ Scalable .NET 8 microservice-style architecture

  • ✅ Angular Backoffice for real operations

  • ✅ Redis & RabbitMQ integration for performance

  • ✅ Full CI/CD pipeline with Docker + Jenkins

  • ✅ Cloud-ready deployment following MVP-level engineering standards

🏁 Next Step

Start with Lesson 1 — Deep Dive into Architecture Diagrams: Clean Architecture, Layered Design, and Separation of Concerns for Scalability, where we’ll understand the project structure, plan core modules, and prepare the development environment.
