1. Cost Management for AI Workloads with AWS Athena Workgroup Configurations


    When dealing with AI workloads on AWS, one often has to process large datasets that can incur significant costs. AWS Athena is a serverless interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL. To optimize cost and manage usage effectively, you can use AWS Athena workgroups. Workgroups allow you to set data usage control limits to prevent queries from consuming excessive amounts of data and accruing unexpected charges. Additionally, you can configure workgroups to publish CloudWatch metrics, enabling you to monitor the amount of data scanned by queries and the overall cost.

    Below you will find a Pulumi program written in Python that configures an Athena workgroup tailored for cost management. The program uses aws.athena.Workgroup, a Pulumi resource which represents an AWS Athena workgroup. Here's how the program will manage costs:

    1. Data usage controls: Set a maximum amount of data that can be scanned by queries in the workgroup. If a query goes over this limit, it will be terminated.
    2. Enforce workgroup configuration: Force Athena to use the settings defined in the workgroup for queries executed within it.
    3. CloudWatch metrics: Enable the publication of CloudWatch metrics for the workgroup. You can use these metrics to create alarms and dashboards, which can help you monitor costs.

    Please note that you'll need your AWS environment configured with the necessary credentials before running a Pulumi program. Now let's go through the details of setting up an AWS Athena workgroup for cost management purposes:

    import pulumi import pulumi_aws as aws # Create an AWS Athena workgroup focused on cost management for AI workloads. # The `aws.athena.Workgroup` resource allows you to configure various query settings which aid in managing costs. cost_management_workgroup = aws.athena.Workgroup("cost_management_workgroup", name="CostManagementAIWorkgroup", description="Workgroup for managing AI workload costs", state="ENABLED", # Ensures the workgroup is in an ACTIVE state tags={ "Purpose": "AI Workload Cost Management", }, configuration={ # Configuring engine version. You should choose the engine version that matches your requirements. "engineVersion": { "selectedEngineVersion": "2", # The version of the query engine }, # Result configuration specifies where to output query results and ensure they are encrypted. "resultConfiguration": { "outputLocation": "s3://my-athena-query-results-bucket/", # Specify your S3 bucket for query results "encryptionConfiguration": { "encryptionOption": "SSE_S3", # Server-side encryption with Amazon S3-managed keys }, }, # Sets a limit on the amount of data that can be scanned by any single query "bytesScannedCutoffPerQuery": 100000000, # The cutoff in bytes, e.g., 100MB here # Ensure queries can't override the workgroup's data settings. "enforceWorkgroupConfiguration": True, # Option to publish query performance metrics to CloudWatch. "publishCloudwatchMetricsEnabled": True, # Expecting payers of the data transfer costs. "requesterPaysEnabled": False, # If set to True, the requester of the query pays the cost for data scanned. } ) # Output the Workgroup name, which can be used to reference the Workgroup in queries. pulumi.export("workgroup_name", cost_management_workgroup.name)

    In this Pulumi program, we're setting up a workgroup that puts a cap on the amount of data scanned (100MB for demonstration). Queries that attempt to scan data beyond this threshold will be stopped automatically. We've also enabled mandatory workgroup configuration and CloudWatch metrics for monitoring. All results will be outputted to the specified S3 bucket location encrypted with Amazon S3 server-side encryption.
