Microsoft Azure Stack Hub is a hybrid cloud platform that allows you to manage services and applications in your datacenter similar to how you work on the Azure cloud. Planning the deployment of the App Service resource provider is crucial when preparing for the AZ-600: Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam. In this post, we will look at the primary considerations and steps to successfully plan your App Service resource provider deployment.
Understanding App Service Resource Provider
The App Service resource provider enables the delivery of Azure Web Apps, API Apps, Mobile Apps, and Function apps on Azure Stack Hub. It provides the following services:
- Web Apps: Enables developers to program web applications in different programming languages.
- APIs: Allow the creation of enterprise-grade APIs secured by Azure AD.
- Azure Functions: Serverless compute service for running event-triggered pieces of code.
Deployment Models
Azure Stack Hub supports two deployment models for the App Service.
- Connected Model – This model requires an internet connection to Azure because certain features such as the resource provider, a NuGet feed for themes and Site Extensions, and the App Service gallery package require Azure connectivity.
- Disconnected Model – In a no-internet-access scenario, the Azure Stack Hub deployment operates in a disconnected mode.
Hardware Requirements
- RAM: Azure Stack Hub requires a minimum of 16 GB of RAM for the controller and 8 GB each for the workers.
- CPU: A minimum of 2 CPU cores for the controller and 2 for each worker.
- Disk: 50 GB of free disk for every role.
Prerequisites
Before deploying the App Service on Azure Stack Hub, ensure you have the following:
- Azure Stack Hub deployed with appropriate region.
- A plan and offer that includes the App service.
- An active Azure AD Tenant.
Steps to Plan the App Service Deployment
- Step 1: Fulfill prerequisites
Ensure that all the system and organizational prerequisites are fulfilled. - Step 2: Determine deployment model
Decide whether to use a connected or disconnected deployment model based on the organization’s needs and resources. - Step 3: Define hardware resources
Detail out the hardware resources required for the deployment. - Step 4: Scale-out decisions
Based on the expected workload, decide on the number of scale units to deploy. - Step 5: Choose software deployment
Choose the right software like Database, Scaling, Function, and others necessary for deployment. - Step 6: Define Network integration
Provide Azure Stack Hub specific information like the VNET, Subnet, IP Pool, DNS Forwarder, NTP Server, and others. - Step 7: Define Service configurations
Specify the service configuration, for instance, custom domains, certificates, compute, and others as needed. - Step 8: Deploy Test
Finally, deploy the App Service and ensure all services are working as expected.
In conclusion, correctly planning the App Service resource provider deployment for Azure Stack Hub requires understanding the needs of the organization, fulfilling prerequisites, determining the deployment model, defining hardware resources and service configurations, and testing the deployment. This will ensure an efficient and seamless transition to the deployment of Azure Stack Hub in your environment.
