 # Service Fabric Getting Started Sample
 This repository contains an introductory sample project for [Microsoft Azure Service Fabric](https://azure.microsoft.com/services/service-fabric/). The sample project contains a single application with multiple services demonstrating the basic concepts needed to get you started building highly-available, scalable, distributed applications.

+### Guest EXE Backend Service
+This is a simple [guest executable service](https://docs.microsoft.com/azure/service-fabric/service-fabric-deploy-existing-app) that is not built on Reliable Services, Reliable Actors, or any Service Fabric APIs. It is a pre-compiled EXE that is packaged up and run on Service Fabric as-is. The EXE is a simple web server that returns the machine name of the node it is currently running on.

 ### Stateless Backend Service
 This is a stateless back-end service using [Service Remoting](https://docs.microsoft.com/azure/service-fabric/service-fabric-reliable-services-communication-remoting). This service demonstrates a basic back-end service that can be used for processing work with an RPC API to check the status of that work.
