1. Managed Deployment Strategies for AI Workflows


    Managed deployment strategies for AI workflows typically involve automating the process of deploying and managing machine learning models in various environments. This can include tasks such as model validation, versioning, scaling, monitoring, and updating the models as necessary.

    Pulumi provides infrastructure as code to assist with deploying AI workflows on different cloud providers. The following Pulumi program in Python demonstrates how to deploy an Azure Machine Learning workspace and a related deployment of an online machine learning model. This is an example reflecting a common pattern for AI workflow deployment, utilizing Azure Machine Learning resources.

    In this example, we will:

    1. Create an Azure Machine Learning Workspace which provides a centralized place to work with all the artifacts used by the machine learning project.
    2. Deploy an online Endpoint, which is a web service providing a REST API to your deployed model. The online deployment refers to the process where the model is hosted, and inference (prediction) requests can be made in real-time.

    Here's a basic structure of the program:

    import pulumi import pulumi_azure_native as azure_native # Creating an Azure Machine Learning Workspace # The workspace is a foundational block for machine learning lifecycle management. ml_workspace = azure_native.machinelearning.Workspace("myMlWorkspace", resource_group_name="myResourceGroup", # Replace with your resource group name location="East US", # Select the appropriate Azure region workspace_name="myUniqueWorkspaceName", # Choose a unique name for your workspace sku=azure_native.machinelearning.SkuArgs( name="Basic", # The SKU name. "Basic" or "Enterprise" tier for example ) ) # Creating an Azure Machine Learning Online Endpoint # Online Deployments provide real-time REST endpoints for making predictions with your models. online_endpoint = azure_native.machinelearning.OnlineDeployment("myOnlineDeployment", endpoint_name="myEndpoint", # Choose a name for your endpoint deployment_name="myDeployment", # Select a name for your deployment resource_group_name=ml_workspace.resource_group_name, workspace_name=ml_workspace.name, online_deployment_properties=azure_native.machinelearning.OnlineEndpointDeploymentPropertiesArgs( sku=azure_native.machinelearning.EndpointDeploymentSKUArgs( name="Dedicated", # Specify the pricing tier ), # Additional properties such as compute type, scaling, etc. can be specified here. ) ) # Export the properties of the deployed resources for future use pulumi.export("workspace_url", ml_workspace.workspace_url) pulumi.export("online_endpoint_url", online_endpoint.scoring_uri)

    Before running this program, ensure that you've set up the Pulumi and Azure environments correctly:

    • Install the Pulumi CLI and Python language runtime on your local machine.
    • Log in to the Azure CLI and set the appropriate subscription.
    • Use pulumi login to log in to the Pulumi service.
    • Initialize a new Pulumi project using pulumi new azure-python.

    In the program above, we are deploying a machine learning infrastructure on Azure, which includes setting up a workspace for organizing and managing all machine learning work in a centralized environment. The workspace creation is followed by deploying an online endpoint for real-time predictions using the deployed model.

    Please update the placeholders such as resource_group_name, workspace_name, endpoint_name, etc. with the values appropriate to your environment. You might need additional configurations depending on your specific requirements.

    Once the resources are deployed, you can access their properties using the Pulumi outputs. Here we export the workspace URL and the endpoint scoring URI, which you can then use in your applications to interact with the machine learning model hosted in Azure.

    Keep in mind this is a simplified example. Depending on your workflow, you may need to add additional steps, such as deploying the actual models, setting up the compute resources, configuring security, etc. Azure Machine Learning provides various configurations and you can manage all of these through the Pulumi infrastructure as code.
