This comprehensive guide shows you how to deploy a hybrid app that spans both Azure and Azure Stack Hub and uses a single on-premises data source. By using a hybrid cloud solution, you can combine the compliance benefits of a private cloud with the scalability of the public cloud. Your developers can also take advantage of the Microsoft developer ecosystem and apply their skills to the cloud and on-premises environments.

The tutorial covers the following key steps:

  1. Deploy a Hybrid-Connected SQL Server Database Server: Learn how to deploy a SQL Server VM in Azure Stack Hub that can be accessed by web apps in both Azure and Azure Stack Hub.

  2. Create Web Apps in Azure and Azure Stack Hub: Set up web apps in both the public and private cloud that can connect to the on-premises SQL Server database.

  3. Configure DNS for Cross-Cloud Scaling: Configure DNS settings to allow users to access the web apps running in both Azure and Azure Stack Hub, and enable Azure Traffic Manager to route traffic between the environments.

  4. Configure SSL Certificates for Cross-Cloud Scaling: Secure the web apps by configuring SSL certificates for all incoming traffic.

  5. Configure and Deploy the Web App: Integrate the web app with Application Insights for monitoring and alerting, and configure dynamic connection strings to connect to the appropriate SQL database.

  6. Enable Automatic Scaling in Azure: Set up autoscaling rules to automatically scale out the Azure web app when traffic increases, and scale it back in when traffic decreases.

  7. Create a Traffic Manager Profile and Configure Cross-Cloud Scaling: Use Azure Traffic Manager to route traffic between the Azure and Azure Stack Hub web apps based on health and load.

  8. Set Up Application Insights Monitoring and Alerting: Configure Application Insights to monitor the web app and trigger alerts when traffic spikes, automatically redirecting traffic to the Azure environment.

  9. Redirect Traffic Between Azure and Azure Stack Hub: Provide instructions for manually or automatically switching traffic between the Azure and Azure Stack Hub web apps in response to the Application Insights alerts.

This guide empowers Azure Stack Hub operators to deploy a hybrid app that leverages the benefits of both the public and private cloud, while providing a seamless experience for end-users.
