Microservices Architecture and Implementation on .NET 5

You will develop e-commerce modules over Product, Basket and Ordering microservices with NoSQL (MongoDB, Redis) and Relational databases (PostgreSQL, Sql Server) with communicating over RabbitMQ Event Driven Communication and using Ocelot 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 Web API application

• REST API principles, CRUD operations

• MongoDB database connection and containerization

• Repository Pattern Implementation

• Swagger Open API implementation

Basket microservice which includes;

• ASP.NET Web API application

• REST API principles, CRUD operations

• Redis database connection and containerization

• 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

• Using Dapper for micro-orm implementation to simplify data access and ensure high performance

• PostgreSQL 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 AutoMapper packages

• 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

API Gateway Ocelot Microservice

• Implement API Gateways with Ocelot

• Sample microservices/containers to reroute through the API Gateways

• Run multiple different API Gateway/BFF container types

• The Gateway aggregation pattern in Shopping.Aggregator

WebUI ShoppingApp Microservice

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

• Call Ocelot APIs with HttpClientFactory

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

Ancillary Containers

• Use Portainer for Container lightweight management UI which allows you to easily manage your different Docker environments

• pgAdmin PostgreSQL Tools feature rich Open Source administration and development platform for PostgreSQL

Docker Compose establishment with all microservices on docker;

• Containerization of microservices

• Containerization of databases

• 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.
