Experiment Tracking in Machine Learning with S3 Versioning

Question

Pulumi · Accepted Answer

To track machine learning experiments using AWS S3's versioning capabilities, you can create an S3 bucket with versioning enabled. This allows you to keep every version of an object in the bucket, providing a history of models, datasets, or other artifacts that change over time during your machine learning experiments.

Here's how to set up an S3 bucket for experiment tracking in a Pulumi program written in Python:

1. Import the necessary Pulumi libraries.
2. Create an S3 bucket with versioning enabled.
3. Optionally, you can also create an S3 bucket policy to manage access to the bucket and its objects.

Let's walk through the code that accomplishes this:

```python
import pulumi
import pulumi_aws as aws

# Create an S3 bucket with versioning enabled to track ML experiments.
ml_experiments_bucket = aws.s3.Bucket("ml-experiments-bucket",
    acl="private",  # Access control list set to private to restrict access
    versioning=aws.s3.BucketVersioningArgs(
        enabled=True  # Enable versioning to keep a history of each object version.
    )
)

# Export the name of the bucket to easily retrieve it later.
pulumi.export('bucket_name', ml_experiments_bucket.id)
```

In the provided program, we perform the following actions:

- We start by importing Pulumi and the AWS module, which allows us to interact with AWS services.
- We create an S3 bucket named `ml-experiments-bucket` with ACL set to private. This means that the bucket and its content are only accessible by authorized users.
- Versioning is enabled on the bucket using the `BucketVersioningArgs` class, which takes a single argument `enabled` set to `True`. This argument tells AWS to keep previous versions of an object in the bucket, therefore allowing you to go back and retrieve any version of your datasets or models.
- The bucket's unique identifier is exported using `pulumi.export`. This allows you to reference the bucket in other parts of your Pulumi program or in Pulumi stack outputs. The exported bucket ID can be useful when configuring other services that need to access this bucket.

Remember to configure Pulumi with your AWS credentials and specify the region where you want to deploy your resources. Make sure your AWS account has the necessary permissions to create S3 buckets.

This simple setup serves as the backbone for your experiment tracking system. You can upload your machine learning models, datasets, and any artifacts related to your experiments to this bucket. The versioning feature ensures that each upload creates a new version of the object, keeping a historical record of your files that you can access at any point in time.
