This repository shows how to implement Event Sourcing, CQRS and DDD in .NET Core, using a Bank as example.

The code has been used as example accompaining a few series of articles on my personal blog:

An ASP.NET Core API is used as entry-point for all the client-facing operations:

• create customers
• create accounts
• deposit money
• withdraw money

Infrastructure

The Cloud can be hosted on Azure, using Azure Functions, Storage Table to persist Events and Materialized Views, and ServiceBus to broadcast the Events.

An "on-premise" version is available as well, which uses

• Kafka to broadcast the integration events
• MongoDb to store the QueryModels used by the API or SQLServer can be used as persistence layer for aggregates.
• several options are available for the Persistence layer to store aggregates:
  • SQLServer
  • EventStore
  • EvenireDB

The on-premise infrastructure can be spin up by simply running docker-compose up from the root folder.
