🧱 Introduction
When building an enterprise-grade eCommerce backend, it’s not enough to just write working code — you need an architecture that scales, evolves, and remains maintainable over time.
In this lesson, we’ll deep dive into Clean Architecture, Layered Design, and the Separation of Concerns — three pillars that form the foundation of any production-ready system.
We’ll visualize the system using architecture diagrams and set the stage for scalable backend development before we move toward frontend integration.
🧱 Why Architecture Matters
In startups, architecture is often ignored — but in enterprise systems, it determines your application’s lifespan and stability. A poor architecture might work today but will collapse under scaling, maintenance, or team expansion pressures.
A well-structured architecture helps you achieve:
✅ Scalability — handle more users, data, and requests
✅ Maintainability — new developers onboard easily
✅ Flexibility — integrate new technologies without breaking existing features
✅ Testability — independent layers make unit and integration testing simple
🧩 Clean Architecture — Simplified for Real-World Projects
Clean Architecture doesn’t mean overengineering.
It means organizing your system so business logic is independent from frameworks, databases, or external dependencies.
Here’s our simplified adaptation — practical, production-ready, and easy to maintain:
This approach keeps the essence of clean design — but fits naturally into real-world enterprise projects.
🏗️ Project Overview
🔹 Phase 1 — Backend (Core Focus)
This is our primary focus initially.
We’ll build:
- ASP.NET Core 8 Web API
- Application, Domain, and Infrastructure layers
- Database integration with PostgreSQL (then SQL Server & MySQL)
- Caching (Redis)
- Messaging (RabbitMQ)
- Logging & monitoring (Serilog, Seq)
- CI/CD pipelines (Jenkins)
- Cloud deployment setup (Azure or AWS)
- Once this is stable and containerized, we’ll move to Phase 2.
🔹 Phase 2 — Frontend (After Backend Completion)
We’ll build the Ecomros Backoffice using Angular, which will:
- Manage Products, Categories, Orders, and Users
- Integrate directly with our production-ready API
- Use shared DTOs and consistent response models
- Be containerized with Nginx for deployment
🏁 Next Step
Start with Lesson 2A — Creating the base solution, API project, folder structure, dependency injection, environment configuration, where we’ll define the project structure, plan core modules, and prepare the development environment.
