# Connect to Azure Blob Storage from SingleStore

## Overview

To securely access data stored in Azure Blob Storage from SingleStore Helios, you can configure a private endpoint that enables outbound connectivity from your Helios workspace to your Azure storage account. This setup ensures that all traffic stays within the Azure network and does not traverse the public internet.

For more information on loading data from Azure Blob Storage using pipelines, refer to [Load Data from Azure Blob Storage Using a Pipeline](https://docs.singlestore.com/cloud/load-data/data-sources/load-data-from-azure-blob-storage-using-a-pipeline.md).

## How It Works

Helios can connect directly to a customer-managed Azure Blob Storage account using a private endpoint over the Azure network. A private DNS zone is configured to route storage access to the private endpoint. Once configured, all access to Azure Blob Storage from SingleStore automatically uses this private connection.

## Requirements

Before configuring the setup, ensure the following:

* The Azure resource ID of your storage account.
* Authorization to whitelist a third-party subscription ID in your Azure environment.

## Enable Outbound Connectivity

To configure outbound access to your Azure Blob Storage account:

1. Submit a Support request. Open a [Support ticket](https://support.singlestore.com) with SingleStore and include your Azure Blob Storage account's resource ID, in the following format:
   ```
   /subscriptions/<subscription id>/resourceGroups/<resource group name>/Microsoft.Storage/storageAccounts/<storage account name>
   ```

2. Wait for SingleStore to configure the endpoint. After receiving the resource ID, SingleStore creates a private endpoint to your Azure Blob Storage account. A private DNS zone is also created to route storage access through the endpoint.

3. Whitelist the SingleStore subscription. SingleStore will provide its Azure subscription ID. You must whitelist this subscription to grant SingleStore access to your storage account

Once the endpoint and DNS configuration are complete, all connections from your Helios workspace to the specified Azure Blob Storage account will route through the private endpoint.
