# SuperSafeBank 

[![SuperSafeBank](https://circleci.com/gh/mizrael/SuperSafeBank.svg?style=shield)](https://app.circleci.com/pipelines/github/mizrael/SuperSafeBank)

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](https://www.davidguida.net):

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](https://azure.microsoft.com/en-ca/services/storage/tables/?WT.mc_id=DOP-MVP-5003878) to persist Events and Materialized Views, and [ServiceBus](https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-messaging-overview?WT.mc_id=DOP-MVP-5003878) 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](https://eventstore.com/)

  - [EvenireDB](https://github.com/mizrael/EvenireDB)

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