AspnetMicroservices

There is a couple of microservices that 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.
