Shared Data Source for Distributed Machine Learning
PythonTo create a shared data source for distributed machine learning, we will focus on setting up an infrastructure that allows for secure data sharing and processing. For this setup, we'll consider using Azure Machine Learning services because they provide a robust environment for training, versioning, and managing machine learning models and datasets. We'll leverage the Azure Machine Learning Datasets resource to create a shared data source that can be used across different workspaces for distributed machine learning tasks.
Here's how you could define such an infrastructure using Pulumi with Azure:
-
Azure Machine Learning Workspace: This resource is the foundational container that provides an integrated, end-to-end data science and advanced analytics solution. Within this workspace, you'll store machine learning experiments, models, and compute targets.
-
Azure Machine Learning Dataset: This resource helps manage data in a structured way, making it easy to use for machine learning tasks. Datasets in Azure Machine Learning can be versioned, shared, and reused across various experiments and pipelines.
-
Azure Machine Learning Datastore: Azure Machine Learning Datastore is the mechanism that allows you to manage storage accounts and their data, which can then be made available to the datasets and used for training models.
-
Azure Container Registry (Optional): To manage Docker containers for deploying models, you might also consider setting up an Azure Container Registry if your distributed machine learning task involves deploying models as web services or involves complex environments that are best managed using containers.
Let's start by constructing a Pulumi program that creates these resources, ensuring that the dataset is configured for sharing across workspaces.
import pulumi import pulumi_azure_native.machinelearningservices as azure_ml # Configuring the resource group and location for the infrastructure resource_group_name = 'ml_shared_resources_group' resource_group = azure_ml.ResourceGroup(resource_group_name, location='East US') # Creating an Azure Machine Learning Workspace workspace_name = 'distributed_ml_workspace' workspace = azure_ml.Workspace( workspace_name, resource_group_name=resource_group.name, location=resource_group.location, sku=azure_ml.SkuArgs( name="Enterprise" ) ) # Creating a Datastore in the machine learning workspace datastore_name = 'shared_ml_datastore' datastore = azure_ml.Datastore( datastore_name, resource_group_name=resource_group.name, workspace_name=workspace.name, # Here we would connect the actual backing store, such as an Azure Blob Storage account datastore_properties=azure_ml.DatastorePropertiesResourceArgs( # Assume a previously created Azure Storage Account is linked here # Including its appropriate authentication mechanism ) ) # Creating an Azure Machine Learning Dataset for shared use dataset_name = 'shared_ml_dataset' dataset = azure_ml.Dataset( dataset_name, resource_group_name=resource_group.name, workspace_name=workspace.name, dataset_properties=azure_ml.DatasetPropertiesArgs( # Configuration related to the path and type of data # For example, you might specify paths within the Datastore for structured data ) ) # After all resources are provisioned, we can export their properties pulumi.export('workspace_url', workspace.studio_web_url) pulumi.export('datastore_id', datastore.id) pulumi.export('dataset_id', dataset.id)
In this program, we create a resource group and specify its location because resources in Azure are organized and handled within a resource group and particular region. Next, we create an Azure Machine Learning workspace, which is required before we can create or attach any datasets or datastores.
The Datastore is the place where your data resides, and it can be backed by various Azure storage services like Blob storage, Data Lake storage, etc. We reference that storage in the
datastore_properties
.The Dataset is a specific abstraction over data, which can be shared across workspaces and used for training machine learning models. Again, you would provide specific paths and configuration to locate and utilize your data effectively.
Finally, the
pulumi.export
statements at the end of the program will print out the URLs for your workspace and the identifiers for your Datastore and Dataset. These can be used in your machine learning pipelines and by your team members requiring access to the shared data infrastructure.By using such an infrastructure setup, you will be able to share, version, and track datasets across multiple projects, which is essential for collaborative distributed machine learning tasks.
