How do I set up streaming data lakes with AWS Lake Formation using Pulumi?

Best Practices for Setting Up Streaming Data Lakes with AWS Lake Formation

In this explanation, we will cover the essential aspects of setting up a streaming data lake using AWS Lake Formation. The setup will include creating an S3 bucket for raw data storage, setting up an IAM role, and configuring the Lake Formation with best practices.

Key points we will cover:

  1. Creating an S3 bucket for data storage.
  2. Setting up IAM roles and policies for access control.
  3. Configuring AWS Lake Formation permissions.
  4. Properly structuring AWS Lake Formation resources.
import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

export = async () => {
    // S3 Bucket for Raw Data Storage
    const rawDataBucket = new aws.s3.BucketV2("raw_data_bucket", {
        bucket: "my-streaming-data-lake-raw",
        acl: "private",
        tags: {
            Name: "StreamingDataLakeRawBucket",
            Environment: "Production",
        },
    });
    // IAM Role for Lake Formation
    const lakeFormationRole = new aws.iam.Role("lake_formation_role", {
        name: "LakeFormationServiceRole",
        assumeRolePolicy: JSON.stringify({
            Version: "2012-10-17",
            Statement: [{
                Action: "sts:AssumeRole",
                Effect: "Allow",
                Principal: {
                    Service: "lakeformation.amazonaws.com",
                },
            }],
        }),
        tags: {
            Name: "LakeFormationServiceRole",
            Environment: "Production",
        },
    });
    // IAM Policy for S3 Access
    const lakeFormationS3Policy = new aws.iam.Policy("lake_formation_s3_policy", {
        name: "LakeFormationS3AccessPolicy",
        description: "Policy for Lake Formation to access S3 bucket",
        policy: pulumi.jsonStringify({
            Version: "2012-10-17",
            Statement: [{
                Action: [
                    "s3:GetObject",
                    "s3:PutObject",
                    "s3:ListBucket",
                ],
                Effect: "Allow",
                Resource: [
                    rawDataBucket.arn,
                    pulumi.interpolate`${rawDataBucket.arn}/*`,
                ],
            }],
        }),
        tags: {
            Name: "LakeFormationS3AccessPolicy",
            Environment: "Production",
        },
    });
    // Attach Policy to IAM Role
    const lakeFormationRolePolicyAttachment = new aws.iam.RolePolicyAttachment("lake_formation_role_policy_attachment", {
        role: lakeFormationRole.name,
        policyArn: lakeFormationS3Policy.arn,
    });
    // AWS Lake Formation Resources
    const rawDataResource = new aws.lakeformation.Resource("raw_data_resource", {
        arn: rawDataBucket.arn,
        roleArn: lakeFormationRole.arn,
    });
    // Lake Formation Permission for the IAM Role
    const lakeFormationPermission = new aws.lakeformation.Permissions("lake_formation_permission", {
        principal: lakeFormationRole.arn,
        permissions: ["ALL"],
        dataLocation: {
            arn: rawDataBucket.arn,
        },
    });
    return {
        s3BucketName: rawDataBucket.bucket,
        lakeFormationRole: lakeFormationRole.name,
        lakeFormationPolicyArn: lakeFormationS3Policy.arn,
    };
}

Key Points

  • Created an S3 bucket specifically designated for raw data storage.
  • Set up an IAM role with a trust policy to allow AWS Lake Formation to assume it.
  • Defined an IAM policy granting necessary permissions for the Lake Formation service to access the S3 bucket.
  • Attached the IAM policy to the IAM role to ensure proper permissions.
  • Registered the S3 bucket as a resource in AWS Lake Formation.
  • Granted Lake Formation permissions to the IAM role to manage the data location.

Summary

We successfully set up a streaming data lake using AWS Lake Formation by creating essential AWS resources: an S3 bucket for data storage, IAM roles and policies for access control, and configuring Lake Formation permissions. This structured approach ensures secure and efficient management of your streaming data lake.
