Sample .NET Core reference application, powered by Microsoft, based on a simplified microservices architecture and Docker containers.

The chosen domain is an eShop/eCommerce but simply because it is a well-know domain by most people/developers.

For example, the next step (still not covered in eShopOnContainers) after understanding Docker containers and microservices development with .NET Core, is to select a microservice cluster/orchestrator like Docker Swarm, Kubernetes or DC/OS (in Azure Container Service) or Azure Service Fabric which in most of the cases will require additional partial changes to your application's configuration (although the present architecture should work on most orchestrators with small changes).
-> Or moving your databases to HA cloud services, or implementing your EventBus with Azure Service Bus or any other production ready Service Bus in the market.
+> Additional steps would be to move your databases to HA cloud services, or to implement your EventBus with Azure Service Bus or any other production ready Service Bus in the market.

In the future we might fork this project and make multiple versions targeting specific microservice cluster/orchestrators plus using additional cloud infrastructure.

Also, feel free to discuss on any current issue.

However, in a real production environment it is recommended to have your databases (SQL Server and Redis, in this case) in HA (High Available) services like Azure SQL Database, Redis as a service or any other clustering system. If you want to change to a production configuration, you'll just need to change the connection strings once you have set up the servers in a HA cloud or on-premises.
## Related documentation and guidance
-While developing this reference application, we are creating a reference Guide/eBook named "Architecting and Developing Containerized and Microservice based .NET Applications" which explains in detail how to develop this kind of architectural style (microservices, Docker containers, Domain-Driven Design for certain microservices) plus other simpler architectural styles, like monolithic apps that can also live as Docker containers.
