Quickstart: Create an Azure Event Hub

This guide will walk you through the steps to create an Azure Event Hub using the Azure CLI. Event Hubs is a big data streaming platform and event-ingestion service. It can be used to process streaming data in real-time.

Prerequisites

An Azure subscription: If you don't have one, create a free account before you begin.
Install the Azure CLI.

Sign in to Azure

Open your terminal or command prompt and sign in to your Azure account:

az login

Follow the prompts to authenticate. After signing in, the CLI will display a list of subscriptions associated with your account. If you need to select a different subscription, use the az account set command.

Create an Azure Resource Group

A resource group is a logical container into which Azure resources are deployed and managed. Create a resource group if you don't have one already. Replace MyResourceGroup and eastus with your desired name and location.


az group create --name MyResourceGroup --location eastus

Create an Event Hubs Namespace

An Event Hubs namespace is a unique scoping container for Event Hubs. You'll need to create a namespace before you can create Event Hubs within it. The namespace name must be globally unique.

                    
az eventhubs namespace create --resource-group MyResourceGroup --name MyUniqueNamespaceName --location eastus

Note: The namespace name MyUniqueNamespaceName must be globally unique across Azure.

Create an Event Hub

Now that you have a namespace, you can create an Event Hub within it. Replace MyEventHubName with your desired name for the event hub.

                    
az eventhubs eventhub create --resource-group MyResourceGroup --namespace-name MyUniqueNamespaceName --name MyEventHubName

Verify Event Hub Creation

You can list the Event Hubs within your namespace to confirm that it was created successfully:

                    
az eventhubs eventhub list --resource-group MyResourceGroup --namespace-name MyUniqueNamespaceName

This command will output a JSON array containing details of your event hubs, including the one you just created.

Next Steps

Congratulations! You have successfully created an Azure Event Hub. Here are some next steps:

Get connection strings to connect your applications.
Send events from a producer application.
Consume events with a consumer application.
Explore other Event Hubs features.

Remember to clean up resources when you're finished to avoid ongoing charges. You can delete the resource group containing your Event Hubs namespace.
