Microservice-inAction

There is a couple of microservices which implemented e-commerce modules over Catalog, Basket, Discount 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.

Features

• 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

• Microservices Communication :

  • 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

• Discount microservice which includes :

  • 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 and Polly

• 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
