.NET 8 Microservices: DDD, CQRS, Vertical/Clean Architecture

Description

This course comes from a live github aspnetrun microservices repository which verified from community with 2300+ stars and 1300+ forks.

You will learn how to build Microservices on .Net platforms which used Asp.Net Web API, Docker, RabbitMQ, MassTransit, Grpc, Yarp API Gateway, PostgreSQL, Redis, SQLite, SqlServer, Marten, Entity Framework Core, CQRS, MediatR, DDD, Vertical and Clean Architecture implementation using latest codes and best practices of .NET 8 on cloud-native environments.

You will develop e-commerce modules over Product, Basket, Discount and Ordering microservices with NoSQL (PostgreSQL DocumentDB, Redis) and Relational databases (SQLite, Sql Server) with communicating over RabbitMQ Event Driven Communication and using Yarp API Gateway. You can find Microservices Architecture and Step by Step Implementation on .NET which step by step developing this course with extensive explanations and details.

Along with this you’ll develop following microservices and items:

Catalog microservice which includes;

• ASP.NET Core Minimal APIs and latest features of .NET 8 and C# 12

• Vertical Slice Architecture implementation with Feature folders

• CQRS implementation using MediatR library

• CQRS Validation Pipeline Behaviours with MediatR and FluentValidation

• Marten library for .NET Transactional Document DB on PostgreSQL

• Carter library for Minimal API endpoint definition

• Cross-cutting concerns Logging, global Exception Handling and Health Checks

• Dockerfile and docker-compose file for running Multi-container in Docker environment

Basket microservice which includes;

• ASP.NET 8 Web API application, Following REST API principles, CRUD operations

• Redis as a Distributed Cache over basketdb

• Implements Proxy, Decorator and Cache-aside Design Patterns

• Consume Discount gRPC Service for inter-service sync communication to calculate product final price

• Publish BasketCheckout Queue with using MassTransit and RabbitMQ

Discount microservice which includes;

• ASP.NET gRPC Server application

• Build a Highly Performant inter-service gRPC Communication with Basket Microservice

• Exposing gRPC Services with creating Protobuf messages

• Entity Framework Core ORM - SQLite Data Provider and Migrations

• SQLite database connection and containerization

Microservices Communication

• Sync inter-service gRPC Communication

• Async Microservices Communication with RabbitMQ Message-Broker Service

• Using RabbitMQ Publish/Subscribe Topic Exchange Model

• Using MassTransit for abstraction over RabbitMQ Message-Broker system

• Publishing BasketCheckout event queue from Basket microservices and Subscribing this event from Ordering microservices

• Create RabbitMQ EventBus.Messages library and add references Microservices

Ordering Microservice

• Implementing DDD, CQRS, and Clean Architecture with using Best Practices

• Developing CQRS with using MediatR, FluentValidation and Mapster packages

• Use Domain Events & Integration Events

• Entity Framework Core Code-First Approach, Migrations, DDD Entity Configurations

• Consuming RabbitMQ BasketCheckout event queue with using MassTransit-RabbitMQ Configuration

• SqlServer database connection and containerization

• Using Entity Framework Core ORM and auto migrate to SqlServer when application startup

Yarp API Gateway Microservice

• Implement API Gateways with Yarp Reverse Proxy applying Gateway Routing Pattern

• Yarp Reverse Proxy Configuration; Route, Cluster, Path, Transform, Destinations

• Rate Limiting with FixedWindowLimiter on Yarp Reverse Proxy Configuration

• Sample microservices/containers to reroute through the API Gateways

WebUI ShoppingApp Microservice

• ASP.NET Core Web Application with Bootstrap 4 and Razor template

• Consume YarpApiGateway APIs using Refit Library with Generated HttpClientFactory

• ASPNET Core Razor Tools — View Components, partial Views, Tag Helpers, Model Bindings and Validations, Razor Sections etc.

Docker Compose establishment with all microservices on docker;

• Containerization of microservices

• Orchestrating of microservices and backing services (databases, distributed caches, message brokers..)

• Override Environment variables

On top of all these, you'll learn how to write quality code, not just how to build microservices. In this course you will see the demonstrating a layered application architecture with DDD best practices. Implements NLayer Hexagonal architecture (Core, Application, Infrastructure and Presentation Layers) and Domain Driven Design (Entities, Repositories, Domain/Application Services, DTO's...) and aimed to be a Clean Architecture, with applying SOLID principles in order to use for a project template. Also implements best practices like loosely-coupled, dependency-inverted architecture and using design patterns such as Dependency Injection, logging, validation, exception handling and so on.

Is this course for you?

This course is very practical, about 95%+ of the lessons will involve you coding along with me on this project. If you are the type of person who gets the most out of learning by doing, then this course is definitely for you.

Tools you need for this course

In this course all the lessons are demonstrated using Visual Studio as a code editor. You can of course use any code editor you like and any Operating system you like as long as it's Windows or Mac. Also using Docker Desktop in order to use different database providers.
