Defining Runtime Parameters for AI Applications

Question

Pulumi · Accepted Answer

When it comes to defining runtime parameters for AI applications, cloud providers offer various services that allow for customization of the computational environment to suit different needs, such as specific machine types, environment variables, GPUs, etc.

In this context, if you're looking to create a configurable environment for an AI application, you might use managed services like AWS RoboMaker, Google Cloud AI Platform Notebooks, or Azure Machine Learning depending on your cloud provider. These services provide a way to define runtime configurations, which are sets of parameters that your AI application will use at run time.

For example, if you're working with Google Cloud's AI Platform, you might use the `Notebook` and `Runtime` resources to define the environment where your AI code will run. You could specify the machine type (e.g., standard, high-memory, high-CPU), whether you need GPUs, the installed libraries, and other configurations critical to running your AI application effectively.

Below is an example Pulumi program that creates a Google Cloud AI Platform notebook with a custom runtime configuration. This program is written in Python using Pulumi's infrastructure as code approach. The runtime configuration is defined within the `Runtime` resource, where you can set properties like the machine type, the presence of a GPU, and any custom software configurations.

```python
import pulumi
import pulumi_gcp as gcp

# Create a Google Cloud AI Platform Notebooks instance
notebook_instance = gcp.notebooks.Instance("my-notebook-instance",
    location="us-central1",
    machine_type="n1-standard-4",  # defines the instance type
    post_startup_script="""
        #! /bin/bash
        sudo apt-get update
        sudo apt-get install -y python3-pip
        pip3 install tensorflow keras
        """  # post-startup script used to install additional libraries
)

# Create a custom runtime for the Notebook instance
notebook_runtime = gcp.notebooks.Runtime("my-notebook-runtime",
    location="us-central1",
    machine_type="n1-standard-4",  # defines the runtime machine type
    software_config=gcp.notebooks.RuntimeSoftwareConfigArgs(
        idle_shutdown=True,
        idle_shutdown_timeout=600,  # shutdown the instance after 10 minutes of idleness
        install_gpu_driver=True,
        custom_gpu_driver_path="",  # path to a custom GPU driver
        post_startup_script=notebook_instance.post_startup_script,  # reuse the startup script from the instance
    ),
    access_config=gcp.notebooks.RuntimeAccessConfigArgs(
        runtime_owner="user@example.com",
    )
)

# Export the instance URL which will be used to access the Jupyter notebook
instance_url = pulumi.Output.concat("https://", notebook_instance.location, "-notebook.googleapis.com/v1/", notebook_instance.service_account)
pulumi.export('notebook_instance_url', instance_url)
```

In the code above:

- We created an AI Platform Notebook instance using the `gcp.notebooks.Instance` resource, where we specified the machine type and a startup script that installs TensorFlow and Keras upon instance creation.
- We then defined a custom runtime configuration using the `gcp.notebooks.Runtime` resource. Here we set up an idle shutdown feature to save on costs, enabled GPU support, and reused the startup script from the notebook instance.
- Lastly, we exported the URL of the Jupyter notebook, which is a concatenation of several attributes from the notebook instance, allowing users to access the Jupyter notebook through this URL once the setup is complete.

It's important to understand that the example above is for Google Cloud's AI Platform Notebooks, but similar concepts would apply if you were to configure AI applications on AWS or Azure with their respective services and Pulumi resources.

Please replace the dummy values and add any additional configurations needed for your specific AI application to run.
