This architecture plan allows secure communication between your SharePoint Online to CardioLog Analytics tracking app that is located in Azure, to the CardioLog Analytics onprem server that is located in your private network.

This solution consists of Azure App Service with Hybrid Connection.

The Hybrid Connection feature of Azure App Service supports making calls to an endpoint in your private network. Hybrid connections are defined against specific host and port combinations, and don’t require you to expose an internet-accessible endpoint or configure a VPN.

For more information, please see Azure App Service Hybrid Connections

Configuration Steps

Step 1 – Create Azure App Service to host the CardioLogAgent web application

1. Browse to the Azure Portal
2. Web > select App Services
3. Click Create
4. Create Web App:
   1. Project Details > Fill out the Subscription and Resource Group
   2. Instance Details:
      1. Name: This will be subdomain of .azurewebsites.net. For example, mycompany-cardiologagent.azurewebsites.net
      2. Publish: Code
      3. Runtime stack: ASP.NET V3.5
      4. Operating System: Windows
      5. Region: select region of your choice. Prefer the closest to your end users.

Step 2 – Deploy CardioLogAgent resources into the created App Service

1. In the CardioLog installation folder > open CardioLogAgent folder > select all the files and folders, right click and zip them into a zip archive. The resulted .zip file must not include the top level CardioLogAgent folder but only the files and folders.
2. In Azure, go to the App Service main screen > App Service Editor > Drag and drop the zip file into the WWWRoot folder
3. Right click the zip file > Extract All

 

Step 3 – Configure CardioLogAgent App Service

In Azure, go to the App Service main screen > App Service Editor > open Web.config and update the following keys:

<add key="EventCollectorPath" value="http://[CardioLog server name]:[CardioLog port, default is 29999]/EventCollector/monitor.aspx"/>
<add key="CardioLogRoot" value="http://[CardioLog server name]:[CardioLog port, default is 29999]"/>
<add key="overwriteConnectedUser" value="true" />
<add key="UseSPAuth" value="true" />
<add key="CardioLogAgentRoot" value="[app service URL]" />

Note: The app service URL can be found in the App Service > Overview > URL

Remove the following from <httpRuntime> tag if exists: requestValidationMode="2.0"

Step 4 – Configure the hybrid connection endpoint

1. In Azure, go to the App Service main screen > Settings > Networking > Hybrid Connections > Configure your hybrid connection endpoints
2. Add hybrid connection > Create new hybrid connection:
   1. Name: name of your choice, for example: cardiologagent-hybrid-connection
   2. Endpoint Host: [CardioLog server name]
   3. Endpoint port: [CardioLog port, default is 29999]
   4. Service bus namespace > Create new:
      1. Location: select the same location as the App Service
      2. Name: name of your choice, for example: cardiologagent-service-bus
