Sample Microservices Architecture using .net Core, RabbitMQ and Docker

I created this application just to practice and demonstrate an architecture in microservices with the approach of Domain-Driven Design(DDD).


It has two bounded contexts, Sales and Warehouse which communicate with each other through RabbitMQ message broker. 


The microservices were dockerized and implemented fully decoupled and not directly call each other but with publishing and subscribing to events. 


There are two kinds of events, Domain and Integration events with the consideration of eventual consistency which provided by NHibernate event listeners.


Domain events are just raised in-process (in-memory) and within the same transaction or operation while Integration events first persist in a transactional database and then are published to the message broker by a worker service. 


Command Pattern provided by MediatR is used to handle new requests which are sent to the microservices.


I also created a Single Page Application(SPA) with Angular which currently just sends creation of order to the Sales microservice. I have not created any API Gateway yet but I will.
