Configuring Auto-inflate on Azure Event Hubs to manage throughput

Question

Pulumi · Accepted Answer

Configuring auto-inflate on Azure Event Hubs is useful when you need to scale the number of throughput units automatically based on the traffic. This ensures that your Event Hub can handle increasing loads without the need for manual intervention.

In Pulumi, we can automate the setup of an Azure Event Hubs Namespace with auto-inflate enabled by using the `azure-native.eventhub.Namespace` resource. This resource allows us to define the namespace that will contain our Event Hub.

Here's how you can do it in TypeScript:

- First, you import the necessary libraries.
- You then create an Event Hubs Namespace with auto-inflate enabled.
- `isAutoInflateEnabled`: When set to `true`, enables the auto-inflate feature.
- `maximumThroughputUnits`: Specifies the maximum number of throughput units to which the namespace can automatically scale.

Below is the TypeScript program that demonstrates how to enable auto-inflate on an Azure Event Hub Namespace:

```typescript
import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";

// Create an Azure Resource Group
const resourceGroup = new azure_native.resources.ResourceGroup("resourceGroup");

// Create an Event Hubs Namespace with Auto-Inflate enabled
const namespace = new azure_native.eventhub.Namespace("namespace", {
    resourceGroupName: resourceGroup.name,
    location: resourceGroup.location,
    sku: {
        name: "Standard",  // The SKU "Standard" is required for Auto-Inflate
    },
    isAutoInflateEnabled: true,              // Enabling Auto-Inflate
    maximumThroughputUnits: 10,              // Setting the maximum throughput units
});

// Export the Event Hubs Namespace name
export const namespaceName = namespace.name;
```

This program sets up an Azure Event Hub Namespace with the auto-inflate feature enabled and a maximum throughput of 10 units. The auto-inflate feature will scale the throughput units based on the demand automatically.

After running this Pulumi program, you will have an Event Hub Namespace ready to be used with the auto-scale feature, helping to manage the throughput of your events seamlessly. Please keep in mind that the auto-inflate feature is available only in the Standard and Dedicated tiers of the Event Hubs offering.

To deploy this program, you would run `pulumi up` in your CLI after setting up your Pulumi stack and Azure credentials. This will provision the resources as defined in the program in your Azure subscription. Make sure to review the changes and confirm the deployment when prompted by Pulumi.
