Connect to Azure Blob Storage

Clicking Azure Blob Storage opens the "Add a connection" dialog with the following fields.

Connection Name: A user-defined display name for this connection.

Description: A brief text description of what this connection is used for.

Authentication Type: A dropdown that specifies how Tellius authenticates with Azure.

1. Client Credentials - uses an Azure Active Directory (Entra ID) app registration to authenticate via OAuth 2.0 client credentials flow. This is the recommended approach for server-to-server authentication.

• Client ID - The Application (client) ID of the Azure AD app registration that Tellius will use to authenticate. You can find this in the Azure portal. This field is masked after entry.

• Client Secret - The client secret generated for the Azure AD app registration. This acts as the password for the app registration and is used together with the Client ID and Tenant ID to obtain an access token. Client secrets have expiration dates, so ensure the secret is current.

• Tenant ID - The Directory (tenant) ID of your Azure Active Directory tenant. This identifies which Azure AD instance Tellius should authenticate against. You can find this in the Azure portal under Azure Active Directory > Overview.

1. Storage Account Key - The access key for your Azure Storage account. You can find this in the Azure portal under your Storage Account > Access Keys. Azure provides two access keys (key1 and key2) for rotation purposes; either one will work. This key grants full read (and write) access to the storage account. This field is masked after entry.

Start Date: An optional date picker that specifies the earliest date from which Tellius should pull files. Only blobs created or modified on or after this date will be synced. If left empty, Tellius syncs all files in the container.

Azure Blob Storage Account Name: The name of the Azure Storage account that contains the container you want to connect to. This is the storage account name as it appears in the Azure portal (for example, "mystorageaccount").

Azure Blob Storage Container (Bucket) Name: The name of the specific container within the storage account that Tellius should connect to. For example, "yourcontainer". Tellius will ingest all supported files within this container.

Scheduled Sync: Configures how frequently Tellius automatically syncs files from this Azure container.

• Manual - Tellius will only sync when you explicitly trigger it using the Synchronize action from the three-dot menu on the connections table.

• Schedule - Set automatic recurring syncs so that new files added to Azure Blob are automatically pulled into Tellius without manual intervention. A second dropdown appears: Cron Schedule (UTC).

The Cron Schedule dropdown lets you define how frequently Tellius automatically syncs files from the connected source. All schedule times operate in UTC, so factor in your local timezone when choosing a schedule. The available options are:

• Hourly

• Every 6 hours

• Daily at midnight

• Daily at 2 AM

• Every 12 hours

Choose a schedule frequency that matches how often new content arrives in your source. Over-frequent syncing on a source that rarely changes adds unnecessary processing load, while under-frequent syncing on an active source means Kaiya may not have access to the latest files.

Click Continue to proceed with creating the connection, or Cancel to discard the configuration.
