AI Data Provenance Tracking using AWS QLDB

Question

Pulumi · Accepted Answer

AWS Quantum Ledger Database (QLDB) provides a transparent, immutable, and cryptographically verifiable transaction log ‎owned by a central trusted authority. QLDB tracks each and every application data change and maintains a complete and verifiable history of changes over time. This makes it an excellent choice for implementing data provenance tracking solutions.

Below, I'll guide you through setting up a simple QLDB ledger in AWS using Pulumi, which could serve as the foundation for a data provenance tracking system.

In this program, we will:

- Create a QLDB ledger resource using `aws.qldb.Ledger`. This resource represents a QLDB ledger that records all transactions.
- Specify the permissions mode for the ledger to determine whether standard or administrative permissions are required. For provenance tracking, administrative permissions are recommended.
- Optionally, you can enable deletion protection to prevent the ledger from being accidentally deleted.

Here is a Pulumi program written in Python that creates a QLDB ledger:

```python
import pulumi
import pulumi_aws as aws

# Create a QLDB ledger
qldb_ledger = aws.qldb.Ledger("provenanceLedger",
    # The name of the ledger. This needs to be unique within your AWS account.
    name="ProvenanceLedger",
    
    # This should be set to ALLOW_ALL for full permissions so that QLDB can properly record transactions.
    permissions_mode="ALLOW_ALL",
    
    # You can enable deletion protection to prevent accidental deletion of the ledger.
    deletion_protection=True,
    
    # Tags are optional key-value pairs that can help you manage, identify, organize, search for, and filter resources.
    tags={
        "Purpose": "ProvenanceTracking"
    }
)

# Output the ARN of the QLDB ledger
pulumi.export("ledger_arn", qldb_ledger.arn)

# Output the name of the QLDB ledger
pulumi.export("ledger_name", qldb_ledger.name)
```

After setting up the QLDB ledger, you can integrate it with other AWS services, such as AWS Lambda or Amazon Kinesis, to process the ledger's journal stream for real-time analysis or external storage. This is not covered in the basic setup but can be added according to your use case.

To run this Pulumi program, you need to have the Pulumi CLI installed and AWS credentials configured. This program will automatically create the specified QLDB ledger when the `pulumi up` command is executed.

If you would like to further explore the particular Pulumi classes and methods used in this solution, please see the Pulumi documentation for AWS QLDB:

Remember that after deploying infrastructure with Pulumi, you can update it as needed by modifying the Pulumi code, and then rerunning `pulumi up`. Pulumi will compute the minimal diff and apply the changes for you. The Pulumi CLI provides a detailed preview of changes before they are applied, ensuring that you have full control and understanding of changes in your infrastructure.
