+# Overview
+
+> This page is part of the "[Deploying Kubernetes Clusters on Azure Stack Hub](/README.md)" deployment guide.
+
+The demo application is based on the [Azure Kubernetes Service Workshop](https://docs.microsoft.com/en-us/learn/modules/aks-workshop/). 
+
+## Application
+
+It is a 3-Tier Web Application using NodeJS and mongoDB:
+
+![application architecture](https://docs.microsoft.com/en-us/learn/modules/aks-workshop/media/01-app-overview.svg)
+
+You can find the application components on GitHub:
+
+* [MicrosoftDocs/mslearn-aks-workshop-ratings-web](https://github.com/MicrosoftDocs/mslearn-aks-workshop-ratings-web)
+* [MicrosoftDocs/mslearn-aks-workshop-ratings-api](https://github.com/MicrosoftDocs/mslearn-aks-workshop-ratings-api)
+
+### Container Images
+
+We've as part of this pattern pre-build the Docker container images for you:
+
+* [demo-rating-api](https://hub.docker.com/repository/docker/heoelri/demo-rating-api)
+* [demo-rating-web](https://hub.docker.com/repository/docker/heoelri/demo-rating-web)
+* [demo-rating-mongodb](https://hub.docker.com/repository/docker/heoelri/demo-rating-mongodb)
+
+The subdirectory mongodb contains a Dockerfile based on mongo (from docker hub) with sample data from [here](https://github.com/MicrosoftDocs/mslearn-aks-workshop-ratings-api/tree/master/data).
+
+### Helm Chart
+
+This directory also contains a helm chart to deploy the whole application.

+# Partner Solutions
+There are Microsoft Partner solutions that can extend the capabilities of Azure Stack Hub. This document includes some that have been found useful in deployments of applications running on Kubernetes clusters.  
+
+## Storage and Data solutions
+
+As described in the overview section of the sample solution, Azure Stack Hub currently does not have a native solution to replicate storage across multiple Azure Stack Hub instances. Unlike in Azure, the capability of replicating storage across multiple regions does not exist - each instance is its own distinct cloud.  However, solutions are available from Microsoft Partners that enable storage replication across Azure Stack Hubs and Azure. 
+
+
+**SCALITY**
+
+Scality delivers web-scale storage that has powered digital businesses since 2009. The Scality RING, our software-defined storage, turns commodity x86 servers into an unlimited storage pool for any type of data –file and object– at petabyte scale.
+
+https://www.scality.com/
+
+**CLOUDIAN**
+
+Cloudian simplifies enterprise storage with limitlessly scalable storage that consolidates massive data sets to a single, easily managed environment.
