1. Scalable ML Model Inference with GCP Cloud Tasks


    To create a scalable Machine Learning (ML) model inference setup with Google Cloud Platform (GCP) using Pulumi, you generally need to follow these steps:

    1. Model Deployment: Deploy your ML model on a service like Google Cloud AI Platform, which can serve the model for inference.
    2. Task Queues: Set up Google Cloud Tasks to manage the queue of inference requests, which allows you to process requests asynchronously and scale according to demand.
    3. Service Invocation: Use a service, such as Google Cloud Functions or Google Cloud Run, to pull tasks from the queue and send them to the deployed ML model for inference.
    4. Results Handling: Optionally, store the results of the inference in a database or notification service for later retrieval or processing.

    Below is a Pulumi program written in Python which outlines how to set up a simple ML inference pipeline using the resources you need for each step, leveraging the relevant GCP and Pulumi services and best practices:

    import pulumi import pulumi_gcp as gcp # Step 1: Deploy the ML model using AI Platform (Google Cloud Machine Learning Engine) # We'll create an EngineModel resource which represents our ML model. # The 'name' is the unique identifier for the model within the project. model = gcp.ml.EngineModel("ml-model", # Specify the project and region as required. project="your-gcp-project", regions="us-central1", # Optionally add labels and description for management. labels={"env": "production"}, description="ML model for inference", # The defaultVersion represents the version to use for online prediction. defaultVersion={ "name": "v1", # Change to your model version "description": "Initial version", }, # Enabling logging for online predictions (optional). onlinePredictionLogging=True) # Provide a link to the EngineModel documentation. # https://www.pulumi.com/registry/packages/gcp/api-docs/ml/enginemodel/ # Step 2: Set up Google Cloud Tasks with a task queue to manage inference requests. # This queue will hold tasks that represent model inference requests. queue = gcp.cloudtasks.Queue("inference-queue", # Again, specify project and region. project="your-gcp-project", location="us-central1", # Define rate limits and retry configuration for task processing. rateLimits={ "maxDispatchesPerSecond": 500, # Customize as needed. }, retryConfig={ "maxAttempts": 5, # Customize as needed. }) # Provide a link to the Cloud Tasks Queue documentation. # https://www.pulumi.com/registry/packages/gcp/api-docs/cloudtasks/queue/ # Step 3: Create a service, such as a Google Cloud Function, to pull tasks and process them. # Note: This step involves creating the actual service which is beyond the scope of this example. # Assuming you have a service ready, you would set it up to pull tasks from your queue. # Step 4: Handle the results of the ML model inference. # This step would typically involve writing code to store results in a database or send notifications. # This can be done in the service logic you write for processing tasks. # For example, you could use Google Cloud Datastore or Firebase for storage, or use Pub/Sub for notifications. # Finally, export important information that you might need, like the model name and queue locations. pulumi.export("model_name", model.name) pulumi.export("queue_name", queue.name)

    This Pulumi program sets the groundwork for a scalable ML inference setup. Please note that actual inference code (processing tasks from the queue and calling the ML engine) is not part of this infrastructure setup and would typically be deployed as a separate application component, such as a Cloud Function, which would process tasks from the queue and perform inference using the deployed ML model.

    Remember to replace "your-gcp-project" with your actual GCP project ID and adjust the settings for the rateLimits and retryConfig according to your specific use case. The regions should be chosen based on where your model is deployed and where you'd like to process inference requests. The defaultVersion should match the version of the model you have deployed on the AI Platform.
