Optimizing License Usage for AI Compute Intensive Applications

Question

Pulumi · Accepted Answer

When you're dealing with AI compute-intensive applications, one of the critical aspects is cost optimization, especially regarding software license usage. Cloud providers offer various services and resources to help users leverage dedicated infrastructure, which can be optimized for licensing costs.

In Azure, for instance, there are specific resources like `azure-native.machinelearningservices.CapacityReservationGroup` and `azure-native.compute.DedicatedHost`. These resources allow you to reserve capacity for your machine learning workloads and use dedicated hosts where you can optimize license usage, respectively. By using dedicated hosts, you can take advantage of your existing server-bound software licenses eligible for Azure's Hybrid Benefit program.

Below is a Pulumi program written in Python that shows how you might create an Azure Dedicated Host to optimize your software license usage for a compute-intensive AI application. This dedicated host can be especially beneficial if you have existing Windows Server or SQL Server licenses with Software Assurance.

First, we will create a dedicated host group, then we will instantiate a dedicated host within that group. I'll walk you through setting these resources up with Pulumi:

```python
import pulumi
import pulumi_azure_native as azure_native

# First, we create a dedicated host group in your specified Azure region. 
# This group will contain the individual hosts you deploy.
dedicated_host_group = azure_native.compute.DedicatedHostGroup(
    "myDedicatedHostGroup",
    # The location for the dedicated host group. Replace "westus2" with the Azure region you desire.
    location="westus2",
    # Resources like these typically go into a specific resource group within your Azure subscription.
    resource_group_name="myResourceGroup",
    # The platform fault domain count represents the number of fault domains that Azure will allocate for the hosts.
    platform_fault_domain_count=3,
)

# Then, we create a dedicated host within the group we just created.
# This host will be where your AI compute workloads are run.
dedicated_host = azure_native.compute.DedicatedHost(
    "myDedicatedHost",
    # Here you specify the type of host you want to create, which determines the specs (CPU, RAM, etc.).
    # The SKU name corresponds to the specific type of host, replace "DSv3-Type1" with the desired host specification.
    sku=azure_native.compute.SkuArgs(
        name="DSv3-Type1",
    ),
    # The name of the dedicated host group where you'll place this host.
    host_group_name=dedicated_host_group.name,
    # The location should match the location of the host group.
    location=dedicated_host_group.location,
    # The resource group for the dedicated host.
    resource_group_name=dedicated_host_group.resource_group_name,
    # The license type to utilize Azure Hybrid Benefit. Could be "Windows_Server_Hybrid" or "None".
    license_type="Windows_Server_Hybrid",
    # Fault domain for the host to reside within.
    platform_fault_domain=1,
)

# Export the ID of the dedicated host group and host. 
# These outputs can be used to reference the resources in other parts of your infrastructure or for other reasons such as auditing.
pulumi.export("dedicated_host_group_id", dedicated_host_group.id)
pulumi.export("dedicated_host_id", dedicated_host.id)
```

In the script above, you'll need to replace `"myResourceGroup"` with the name of an Azure Resource Group you've created, and `"westus2"` with your desired Azure region. The SKU name `"DSv3-Type1"` is an example SKU for the Azure Dedicated Host; you'll want to replace that with the SKU that fits your AI workload requirements.

Remember, always check the proper documentation and consult Azure's pricing details for dedicated hosts, ensuring that the selected host type and configuration are the most cost-effective for your specific licensing situation and workload needs. This setup is a start towards optimizing your license usage in the cloud for compute-intensive AI applications.
