Object Storage for Azure-based AI Data Lakes

Question

Pulumi · Accepted Answer

Object storage is a key component of data lakes, especially for AI applications where large quantities of unstructured data need to be stored and analyzed. In Azure, you can create a Data Lake Store which is optimized for large-scale analytics. It acts as hyper-scale repository for big data analytics workloads, allowing you to capture data of any size, type, and ingestion speed.

For Azure-based AI data lakes using Pulumi, you would typically utilize resources such as:

- `Account` from `azure-native.datalakestore`: This is the top-level Data Lake Store filesystem account resource. It represents the data lake and provides a scalable, secure data storage location.
- `Datastore` from `azure-native.machinelearningservices`: This is an abstraction on top of the actual storage, used to manage and reference data artifacts used by Azure Machine Learning processes.

Below is a Python program written with Pulumi that demonstrates how to create an Azure Data Lake Store account and a Machine Learning Datastore, which could be utilized for AI Data Lakes. The Datastore could then be used for various machine learning training and inferencing tasks.

First, we'll set up the Pulumi program and import the necessary modules. Then, we'll define variables such as the resource group name, location, account name for the Data Lake Store, and the name of the Machine Learning Datastore.

```python
import pulumi
import pulumi_azure_native as azure_native

# Define the resource group and location where all resources will be provisioned.
resource_group = azure_native.resources.ResourceGroup("ai_data_lake_rg",
                                                     resource_group_name="ai_data_lake_resource_group")

# Create a Data Lake Store account where the AI Data Lake files will be stored.
ai_data_lake_store = azure_native.datalakestore.Account("aiDataLakeStoreAccount",
                                                        resource_group_name=resource_group.name,
                                                        location=resource_group.location,
                                                        account_name="aidatalakestore")

# Define the properties for the Machine Learning Datastore.
# For example, the associated Data Lake Store account and its corresponding file system name.
# If you have existing infrastructure for an AI Data Lake, set the `datastore_name` appropriately.
# In this case, we are assuming the Data Lake Store created above will be used.
datastore_properties = {
    "azure_data_lake_store": {
        "account_name": ai_data_lake_store.name,
        "file_system_name": "file_system_for_ml"
    }
}

# Create an Azure Machine Learning Datastore.
# This Datastore will reference the storage in Data Lake previously created and can be used in machine learning experiments.
ai_ml_datastore = azure_native.machinelearningservices.Datastore("aiMLDatastore",
                                                                 resource_group_name=resource_group.name,
                                                                 location=resource_group.location,
                                                                 name="aidatamlstore",
                                                                 datastore_properties=datastore_properties)

# Export the IDs of the created resources to easily retrieve them later for management or operational tasks.
pulumi.export("resource_group_id", resource_group.id)
pulumi.export("data_lake_store_id", ai_data_lake_store.id)
pulumi.export("ml_datastore_id", ai_ml_datastore.id)
```

To understand what the program is doing, let's go through it step-by-step:

1. We start by importing the necessary modules from Pulumi's Azure-native package, which allows us to provision and manage Azure resources.

2. We create a resource group, a container that houses the resources for an Azure solution. The `ResourceGroup` resource is a logical container into which Azure resources like Azure Data Lake Store and Machine Learning services are deployed and managed.

3. We then provision an Azure Data Lake Store account using the `Account` resource from the `azure-native.datalakestore` namespace. The Data Lake Store provides hyper-scale storage for big data analytics workloads.

4. The Machine Learning Datastore, another crucial component for AI deployments, gets defined and created. This datastore uses properties that connect it to our previously created Data Lake Store account, hence creating a unified data management ecosystem for AI operations.

5. Finally, we export the resource IDs which can then be used to access these resources programmatically or through the Azure portal.

Remember to replace placeholder values, such as the resource group name, account name, and file system name with actual values that suit your scenario. After running this Pulumi program, you will have your data lake store and machine learning datastore set up in Azure, ready for you to start ingesting data and running AI analytics.
