1. Configuration Audit Trails for Machine Learning Workflows.

    Python

    To set up configuration audit trails for Machine Learning (ML) workflows, you'll typically need to capture various kinds of metadata such as training data versions, model versions, code changes, and system configurations. Each ML framework or cloud service might have differing capabilities and services that can be used for this purpose.

    We'll use Pulumi to create a setup that involves:

    1. Versioning data using a data registry, which enables you to manage and track different versions of datasets.
    2. Tracking code and model versions with a model registry, allowing for version control of models and associated code.
    3. Setting up an audit trail with a cloud service that captures and logs changes to your cloud resources, aiding compliance and troubleshooting.

    For this goal, let's consider a setup using AWS as the cloud provider. We will use the following AWS services:

    • AWS S3: To store the datasets with versioning enabled on the buckets.
    • AWS SageMaker: Which contains a Model Registry for tracking different versions of machine learning models.
    • AWS CodeCommit: As a managed source control service to track changes in the code used for training models.
    • AWS CloudTrail: To record user activity and API usage, enabling governance, compliance, operational auditing, and risk auditing of your AWS account.

    Here is a Pulumi program in Python that sets up these resources:

    import pulumi import pulumi_aws as aws # Enable S3 bucket versioning for dataset version control dataset_bucket = aws.s3.Bucket("dataset-bucket", versioning=aws.s3.BucketVersioningArgs( enabled=True, )) # CodeCommit Repository for source control ml_code_repo = aws.codecommit.Repository("ml-code-repo", description="Repository for ML workflow source code") # SageMaker model group to track different model versions model_group = aws.sagemaker.ModelPackageGroup("model-group", model_package_group_name="my-model-group", model_package_group_description="Group of related models for ML workflows") # CloudTrail to monitor and log account activity ml_workflow_trail = aws.cloudtrail.Trail("ml-workflow-trail", s3_bucket_name=dataset_bucket.id, enable_logging=True, event_selector=aws.cloudtrail.TrailEventSelectorArgs( read_write_type="All", include_management_events=True, data_resources=[aws.cloudtrail.TrailEventSelectorDataResourceArgs( type="AWS::S3::Object", values=[pulumi.Output.concat(dataset_bucket.arn, "/")], )] )) # Exporting the bucket ARN to show where the dataset will be stored pulumi.export("dataset_bucket_arn", dataset_bucket.arn) # Exporting the CodeCommit Repository clone URL for HTTPS pulumi.export("ml_code_repo_clone_url_http", ml_code_repo.clone_url_http) # Exporting the ARN of the model package group pulumi.export("model_group_arn", model_group.arn) # Exporting the name of the CloudTrail tracking the ML workflow pulumi.export("ml_workflow_trail", ml_workflow_trail.name)

    Detailed Explanation

    • We start by importing the necessary Pulumi and Pulumi AWS SDK packages.

    • We create an S3 bucket with versioning enabled; this bucket will store our datasets and model artifacts. By enabling versioning, we can keep track of changes across different versions of the data we upload.

    • An AWS CodeCommit repository is set up for storing the source code related to our machine learning workflows. This provides version control for our codebase and helps in tracking changes over time.

    • We define a SageMaker model group that allows us to group related model versions. This model package group is part of the SageMaker Model Registry that helps manage and deploy versions of machine learning models in SageMaker.

    • An AWS CloudTrail trail is created to log and monitor the S3 bucket and potentially other resources. This helps us maintain an audit trail for compliance and troubleshooting. In the event selector, we specify that we want to monitor both read and write activity and include management events related to our dataset bucket.

    • Finally, we export several important identifiers such as the bucket ARN, CodeCommit repository clone URL, model group ARN, and CloudTrail name. These outputs can be used to easily reference these resources in future operations or in other Pulumi stacks.

    This setup will help you maintain a clear and comprehensive audit trail for your ML workflows, track changes to your datasets, code, and models, and ensure robust versioning and governance for your machine learning operations.
