Tutorial / Cram Notes
Prerequisites
Before you begin the deployment, several prerequisites must be met:
- Azure Stack Hub must be running and operational.
- You must have an Azure Stack Hub operator’s Azure AD or AD FS account with the necessary permissions.
- Azure Stack Hub must have internet connectivity to download the App Service binaries.
- Appropriate quotas and plans must be configured.
- Plan for a SQL Server and file server to support the App Service resource provider.
Deployment Process
The App Service resource provider is deployed as a part of the Azure Stack Hub integrated systems environment. To deploy, follow these general steps:
- Download the App Service Resource Provider Installer: You will need to download the installer and helper scripts from the Azure Stack Hub Marketplace.
- Prepare the Infrastructure Roles:
- SQL Server: A dedicated SQL Server instance is required to host the App Service databases.
- File Server: This will be used for content storage for applications and needs to be highly available.
- Prepare the Network: Allocate a range of IP addresses to be used for the App Service; these must be outside of the Azure Stack Hub infrastructure range.
- Deploy the Resource Provider: Run the installer script on a privileged endpoint (PEP) and provide the necessary parameters, such as SQL Server and file server details, to complete the installation.
- Post-Deployment Configuration:
- Configure additional settings, such as scaling options and App Service Plans.
- Verify the App Service is functional by deploying a test application.
- Update Management: Routinely check for updates and apply them to the App Service resource provider to ensure compliance with the latest security and functionality standards.
Management and Scaling Considerations
After successful deployment, you will need to manage the App Service by monitoring its health and usage, scaling the infrastructure based on demand, and performing routine updates and backups.
- Health Monitoring: Use the Admin Portal or Azure Stack Hub monitoring solutions to check the health and performance of the App Service.
- Scaling: The App Service on Azure Stack Hub supports manual scaling. You can scale the roles such as front-ends, workers, and management servers based on your workloads’ needs.
- Backup and Disaster Recovery: Make sure to implement backup strategies for the App Service and associated databases. For disaster recovery, replication can be set up between instances and regions if required.
- Handling Updates: Azure Stack Hub releases updates to the App Service resource provider, which must be applied promptly to ensure security and compliance.
- Quota Management: Monitor and manage user quotas to ensure fair resource allocation and prevent over-utilization of the App Service resources.
- Support and Troubleshooting: Establish a support protocol to handle user and system issues promptly. Use the Azure Stack Hub documentation for troubleshooting common problems.
In summary, planning the deployment of the App Service resource provider involves understanding the prerequisites, carrying out a step-by-step deployment process, and then moving into an operational phase of management and scaling based on usage. Proper planning ensures a secure, reliable, and efficient App Service environment within Azure Stack Hub, capable of hosting a wide range of applications.
