1. Resource Utilization Optimization for AI using Azure Metric Alerts


    To optimize resource utilization for AI workloads using Azure Metric Alerts, you can create alerts that monitor metrics for your resources and trigger actions when certain thresholds are met. These alerts can help you keep an eye on the performance and health of your AI services, such as Azure Machine Learning workspaces, ensuring that you scale resources up or down as needed.

    In Pulumi, you can establish metric alerts on Azure using the azure_native module, which provides native Azure resource management functionality directly mapped to Azure Resource Manager APIs. Below, I'll demonstrate how to create a metric alert for a hypothetical AI resource. For the sake of this example, let's assume we are monitoring the CPU utilization on an Azure Kubernetes Service (AKS), which is hosting our AI workloads.

    The steps to establish a metric alert with Pulumi are as follows:

    1. Set up the Azure provider and obtain the appropriate resource ID for the resource you want to monitor. In this case, let’s assume it’s an AKS cluster.
    2. Create a MetricAlertResource, providing the required criteria such as the metric name (e.g., CPU utilization), the threshold to alert on, the comparison operation (greater than, less than, etc.), and the action group to notify when the alert is triggered.

    Here is a Pulumi program that sets up such an alert:

    import pulumi from pulumi_azure_native import insights, resources, monitoring # First, we need a resource group. If you already have one, you can use get_resource_group. # Otherwise, you can create a new one as shown below: resource_group = resources.ResourceGroup('ai-optimization-rg') # Normally, you'd reference an existing AI resource. For our example, we'll monitor a hypothetical AKS cluster resource. # You would obtain the existing resource using get_aks or similar, but for simplicity, assume the following is the AKS resource ID. aks_resource_id = "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ContainerService/managedClusters/{aksClusterName}" # Define the criteria for the metric alert criteria: insights.MetricAlertCriterionArgs( metric_name="cpuUsage", metric_namespace="Microsoft.ContainerService/managedClusters", name="CpuUsageHigh", operator="GreaterThan", threshold=75, # Set the threshold to 75% CPU usage time_aggregation="Average", dimensions=[ insights.MetricDimensionArgs( name="ClusterName", operator="Include", values=[aks_resource_id.split('/')[-1]], ), ], ) # Define an action group (set up separately) with the relevant notification setup (e.g., emails, SMS, webhooks). action_group_id = "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Insights/actionGroups/{actionGroupName}" # Create the metric alert metric_alert = insights.MetricAlertResource( 'cpu-usage-alert', resource_group_name=resource_group.name, description="Alert when CPU usage is over 75%", severity=3, # Severity from 0 (critical) to 4 (verbose) enabled=True, scopes=[aks_resource_id], evaluation_frequency='PT1M', # Evaluate every minute window_size='PT5M', # Based on the last 5 minutes of metrics criteria=[criteria], action_groups=[ insights.MetricAlertActionArgs( action_group_id=action_group_id, ), ], ) # Expose the alert ID if you need to reference it elsewhere pulumi.export('metric_alert_id', metric_alert.id)

    In this program, MetricAlertResource is used to create a new alert rule. We specify the criteria for triggering the alert, which includes the metric name (cpuUsage), the threshold, and how the metric should be aggregated over time. We also reference an action group that defines what should happen when the alert is triggered – this could include sending emails, triggering a webhook, invoking an Azure Function, etc. You need to replace {subscriptionId}, {resourceGroupName}, {aksClusterName}, and {actionGroupName} with your actual Azure subscription ID, resource group name, AKS cluster name, and action group name.

    This alert will help in automatically monitoring the CPU usage and taking necessary actions if the specified thresholds are reached. Adjusting resource utilization based on metric alerts can help cost optimization and ensure that AI operations run efficiently.
