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
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.
