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
