Tutorial / Cram Notes
Azure Stack Hub is an extension of Azure, bringing the agility and innovation of cloud computing to an on-premises environment. The Event Hubs resource provider allows for the collection, storage, and analysis of large amounts of data that can be generated by connected devices, applications, or infrastructure.
Prerequisites for Deployment
Before deploying the Event Hubs resource provider on Azure Stack Hub, ensure the following prerequisites are met:
- Azure Stack Hub integrated system or Azure Stack Development Kit (ASDK) is operational.
- The Azure Stack Hub operator has installed the latest updates for Azure Stack Hub.
- Azure Stack Hub is registered with Azure to enable marketplace syndication.
- The Event Hubs resource provider binary file is downloaded from the Azure Stack Hub marketplace.
- Required infrastructure roles including PKI certificates, sufficient storage, and networking are properly configured.
Step-by-Step Deployment
1. Download and Install the Event Hubs Resource Provider
The Event Hubs resource provider must be downloaded from the Azure Stack Hub marketplace. After downloading, it can be installed using the provided PowerShell scripts.
2. Prepare the environment
Configuring the environment involves setting up an Azure Active Directory service principal that the resource provider will use. Additionally, ensure network integration is in place for the resource provider to communicate with both the user’s applications and Azure Stack Hub infrastructure.
3. Set up the Resource Provider VM
Deploy a Resource Provider VM that hosts the Event Hubs service. The specifications of this VM depend on the expected workload and are critical for the performance of the system.
4. Register the Resource Provider with Azure Stack Hub
The last step is registering the resource provider with the Azure Stack Hub using Azure Stack Hub admin PowerShell. This allows the Event Hubs services to appear in the tenant portal and for tenants to start using the service.
Capacity Planning and Sizing
| Component | Factor | Description |
|---|---|---|
| Throughput Units (TUs) | Data Ingress/Egress | Estimate the number of TUs to handle peak workloads. |
| Storage Account | Retention and Throughput | Consider the retention policy and the data throughput needed. |
| Network Bandwidth | Data Traffic | Ensure sufficient network bandwidth for internal and external communication. |
| VM Size | Resource Demands | Choose an appropriate VM size for the Resource Provider based on expected workloads. |
Note that thorough testing is necessary to validate the planned capacity and adjust accordingly.
Security and Compliance
Apply Azure Stack Hub security practices including:
- Encrypted communications using SSL/TLS
- Network Security Groups (NSGs) to restrict unnecessary traffic
- Monitoring through Azure Stack Hub monitoring solutions
- Applying Compliance policies for data retention, if necessary
Backup and Disaster Recovery
Back up the Event Hubs resource provider infrastructure and its data regularly. Develop a disaster recovery plan to ensure Event Hubs can quickly be restored or re-deployed after a failure.
Updating and Maintenance
Regular maintenance and updates are necessary to ensure the resource provider is secure, stable, and performing at an optimal level. Follow Azure Stack Hub’s update policy, scheduling updates during maintenance windows and making sure to update the Event Hubs resource provider accordingly.
By carefully planning the deployment of an Event Hubs resource provider on Azure Stack Hub, enterprises can leverage real-time data ingestion and streaming capabilities on-premises, with the scale and flexibility similar to that of Azure. Sizing correctly, planning for security and disaster recovery, and maintaining the system regularly will lead to a successful deployment that meets the needs of a hybrid cloud environment.
Practice Test with Explanation

- (A) Azure Active Directory tenant
- (B) An existing Azure Event Hubs namespace
- (C) An active VPN connection
- (D) A registered App Service resource provider
Answer: A) Azure Active Directory tenant
Explanation: An Azure Active Directory tenant is a prerequisite for deploying an Event Hubs resource provider on Azure Stack Hub to ensure authentication and authorization are properly managed.
True or False: The Azure Stack Hub’s Event Hubs resource provider supports all the features available in Azure Event Hubs.
- (1) True
- (2) False
Answer: False
Explanation: The Event Hubs resource provider on Azure Stack Hub may not support all the features available in Azure Event Hubs due to differences in the local environment and disconnected scenarios.
When planning an Event Hubs resource provider deployment, network integration is not a consideration.
- (1) True
- (2) False
Answer: False
Explanation: Network integration is an important consideration when planning an Event Hubs resource provider deployment as it directly affects connectivity and accessibility.
True or False: Disaster recovery capabilities are automatically set up when you deploy the Event Hubs resource provider on Azure Stack Hub.
- (1) True
- (2) False
Answer: False
Explanation: Disaster recovery capabilities must be explicitly planned and set up as part of the Event Hubs resource provider deployment; they are not automatically configured.
In which scenario would you need to deploy a custom role for the Event Hubs resource provider on Azure Stack Hub?
- (A) To allow users to manage their own Event Hubs namespaces
- (B) To enable billing and metering for Event Hubs
- (C) For the default installation and operation
- (D) To grant permissions beyond the built-in roles
Answer: D) To grant permissions beyond the built-in roles
Explanation: Deploying a custom role for the Event Hubs resource provider on Azure Stack Hub would be necessary to grant permissions that go beyond the capabilities of the existing built-in roles.
True or False: The Event Hubs resource provider on Azure Stack Hub requires the same amount of compute and storage resources as Azure Event Hubs in the cloud.
- (1) True
