Azure Event Hubs is a Big Data streaming platform and event ingestion service, capable of receiving and processing millions of events per second. Event Hubs can process and store events, data, or telemetry produced by distributed software and devices. Data sent to an event hub can be transformed and stored using any real-time analytics provider or batching/storage adapters. For detailed overview of Event Hubs, see Event Hubs overview and Event Hubs features.

In this quickstart, you create an event hub using Azure CLI.

If you don't have an Azure subscription, create an Azure free account before you begin.

Prerequisites

Use the Bash environment in Azure Cloud Shell. For more information, see Quickstart for Bash in Azure Cloud Shell.
If you prefer to run CLI reference commands locally, install the Azure CLI. If you're running on Windows or macOS, consider running Azure CLI in a Docker container. For more information, see How to run the Azure CLI in a Docker container.
- If you're using a local installation, sign in to the Azure CLI by using the az login command. To finish the authentication process, follow the steps displayed in your terminal. For other sign-in options, see Sign in with the Azure CLI.
- When you're prompted, install the Azure CLI extension on first use. For more information about extensions, see Use extensions with the Azure CLI.
- Run az version to find the version and dependent libraries that are installed. To upgrade to the latest version, run az upgrade.

This article requires version 2.0.4 or later of the Azure CLI. If using Azure Cloud Shell, the latest version is already installed.

Set the subscription context

The following steps are not required if you're running commands in Cloud Shell. If you're running the CLI locally, perform the following steps to sign in to Azure and set your current subscription:

Set the current subscription context. Replace MyAzureSub with the name of the Azure subscription you want to use:

az account set --subscription MyAzureSub

Create a resource group

A resource group is a logical collection of Azure resources. All resources are deployed and managed in a resource group. Run the following command to create a resource group:

# Create a resource group. Specify a name for the resource group.
az group create --name <resource group name> --location eastus

Create an Event Hubs namespace

An Event Hubs namespace provides a unique scoping container, referenced by its fully qualified domain name, in which you create one or more event hubs. To create a namespace in your resource group, run the following command:

# Create an Event Hubs namespace. Specify a name for the Event Hubs namespace.
az eventhubs namespace create --name <Event Hubs namespace> --resource-group <resource group name> -l <region, for example: East US>

Create an event hub

Run the following command to create an event hub:

# Create an event hub. Specify a name for the event hub. 
az eventhubs eventhub create --name <event hub name> --resource-group <resource group name> --namespace-name <Event Hubs namespace>

Congratulations! You have used Azure CLI to create an Event Hubs namespace, and an event hub within that namespace.

In this article, you created a resource group, an Event Hubs namespace, and an event hub. For step-by-step instructions to send events to (or) receive events from an event hub, see the Send and receive events tutorials:
